Furnace Air Filter

Furnace Air Filter

Furnace Air Filter

If you read my web page about  air conditioning filters you will probably notice some similarities between these two WebPages. The fact is within your house there is the possibility to use your air ducts for hot and cold air. If you live near the poles of the earth you might not have an A/C system and if you live near the equator you probably don’t having a heating system. I used to live sort of in between and used mine for both, which is optimal.

Now that we have that confusion out of the way lets talk about where you have seen this type of HVAC air filter. In most houses, it will  be in either two places (directly above the furnace or at a higher  level where you can open up a great on the first floor. My house used to have it on the first floor. By the time, most people check it the air filter is super black and dust is flying out of the vent letting  it right back in your house. You do not want to wait this long. You should replace it every 6 months, but if you get a high-quality model you could wait as long as a year!

Furnace Air Filter Types

For the most part, most generic brands are what you call HEPA-like and are only imitators when it comes to collecting air pollutants. You  can only hope they will catch the big dust balls so you don’t have to sweep them up and brush them off your clothes and furniture. I suggest that you make a significant upgrade, which you are probably here to  learn about. I will share two types below with you. I will tell you I prefer the “True HEPA” version, but other people do have the use for the  electronic version.  Furnace Air Filter HEPA

The best type of my belief is furnace air filter help.

This type has HEPA standards that it must keep too. As you probably already know it is 99.97% effective at capturing particles down to 0.3 microns in size, which is very small. This can capture bacteria and viruses pretty well too. That’s one thing you won’t find with the cheap blue ones that only catch large particles that you can see. They also are static charged to attract particles like a tv screen, but will not make a spark like you  will if you rub your feet up against the carpet.

Electronic Furnace Air Filters

The second type is what we call electronic furnace air filters that are a bit different from using static electricity to attract  particles in your air. This process charged the air entering the  system and then makes it pass this an air filter that is charged with  the opposite charge (opposites attract). It seems all natural and good, but not everything is caught in the air filter all the time. Poor designs could leak these charged particles into your house and do what ozone generators do. You can check out my web page ” do ionic air purifiers work” about that situation. In the end, the technology does work, but you will have to choose quality and have a  real need to install something like this. It is actually more of a  whole house air purifier than anything else. However, it is not one that I can approve of using.  Furnace Air Filter Reviews     Within my reviews you will find great information about furnace and  HVAC air filters. Your specific house will need a certain size. You will always want to look at the old one to get the measurements, which are on the outside edge of the air filters. Please don’t get the cheap blue ones! It would be sad for me to know after reading my information you chose to ignore it for the sake of price instead of thinking of  your families health.

  • Smart Controls that do the Thinking for You. Easy to use tap controls with 4 Air Cleaning Levels (SLEEP, GENERAL Cleaning, ALLERGEN Capture Mode and MAX Cleaning Power)

Honeywell AirGenius4 HFD310 is efficient and is very, very quiet. It has a very faint odor when operating and might be what is supposed to mask or reduce other odors. It is so slight that very few notice it but me. I would buy it again since it is one of the better ones I have used.

I have given this thing a workout, and it still keeps going. I use it in my living room where my best friend and I both smoke, and it keeps the air pretty clean. I also keep a window cracked, but this purifier makes a huge difference. I wouldn’t say that my house is free of smoke smell but it pulls all of the second-hand smoke out of the air very well.

I’ve been running this unit daily in my 200 sg/ft home office for the past 4 months. I also have a 70lb Golden Retriever who sleeps in the office every night. The primary purpose of this purchase was to reduce the inevitable, and unpleasant, pet smell.

This unit not only reduced the odor, it eliminated it. I’ve only had to run it on speed 1 (out of 3), which is tolerably quiet and easily cleans the air in this relatively small space. It has a permanent filter that is super easy to access and clean.

Honeywell HFD310 AirGenius4 Air Cleaner2

I am completely happy with this air purifier. It is quiet and does a great job of removing cooking odors in our trailer. I have had terrible allergies this spring and it seems to be helping with that as well. It creates a nice breeze too. I have kept it running 24/7 for a month now.

I have used this unit on max for five months now and I have noticed a significant decrease in the dust on furniture. This air filter is being used in a room around 400 square feet so it does not clean the whole room, but the side of the room that I placed the filter at is much cleaner and I have to dust a lot less.

The oscillating feature has worked well and I have had it oscillating about 6 hours a day each day and there have been no problems with it. The extra charcoal filters work very well in helping remove pet odors and other household smells. Also, it is nice that this unit has a washable filter and that is very easy to clean.

This purifier is very quiet and even on the highest setting, it’s very tolerable. No rattling thus far. I have this in my office and it’s not distracting. I could easily run this on low and sleep with it. This purifier is very powerful and it truly does draw in airborne particles from all angles.

The size is great and I like that it’s a tower. The oscillator feature greatly improves the machine’s effectiveness.

The permanent filter is easy to clean and dry. I apply a spray cleaner and use the sink sprayer to wash it out with hot water. I shake out the excess, blot with paper towels and then use my hair dryer to dry it thoroughly. It takes about 15 mins to wash and dry.

Ideally, it would be nice to have an extra replacement filter. The charcoal pre-filter trapped a lot of dust and pollen and I have replaced that as well. As far as overall performance, it seems to be working just as well and operating just as quietly as always. I’m still impressed and quite pleased with this machine.

This device is well worth the money. Honeywell had designed this product with many options settings to clean your air space. You have the choices of what level of purifying the air 1, 2, 3, and 4. You have the choices of how long you would like the machine to stay on 2, 4,or 8 hour if you want it to move side to side in filtering your air space it would do that too with just a press of a button.

I love that it purifies the room very well. You also even have an indicator light that will let you know that your filters need cleaning. How good is that? It is very easy to clean and it saves you money with not have to buy filters time and time again.

You just take them out and run water over them and let them air dry and then place them back into your machine. Isn’t that easy? But, if you let them go a little too long before cleaning, you might have to let the filter soak in water only, for a while longer. Remember larger space may need several machines.

Holmes HAP9412B-UA Small Room HEPA Type Air Purifier

Holmes HAP9412B-UA Review

Holmes HAP9412B-UA Small Room HEPA Type Air Purifier Holmes HAP9412B works well. You will have a noticeable improvement for allergies, such as dust, dander. This has several settings, also a wide variety of filters available, the filters are a little expensive, but last 4 months. I ‘m happy with this purchase and would recommend it to others.

This has an optional ionizer that can be used; this helps with the negative air ions to attach to the positive ones and helps in the process of air purification. I would purchase this again, reasonable, efficient, light weight.

This filter does a great job of eliminating any odors and really does a great job of minimizing the bird ‘dust’. I am running it in a larger space then the unit calls for and usually only when I need to close the house up, but it works just fine. I am not using it for allergens so I cannot comment on that aspect.

Also, I do run the highest level. I do not find it to be too loud as some have mentioned. It’s not uber quiet but it certainly does not interfere with my TV and I don’t find it louder than a decent quality room fan. I feel it was a good value for the price and so far it’s running just fine.

I have an infant son at home, during the recent LA wildfires, our air quality dropped from Green to Red. Government advisory was to stay indoors and do not go outside to do unnecessary tasks. The entire house smelled like smoke and thank god these are cheap and fast.

Holmes HAP9412B-UA Small Room HEPA Type Air Purifier2

Why do I recommend these filters?

It is a good quality, cheap, durable, lightweight, takes up very little desk space, tall and thin. Its bottom is heavy so it is little difficult to knock over not heavy enough to injury a toddler if it fell. It can easily go on a nightstand.

Easy to use, Speeds 1 and 2 are very quiet, like low humming, quieter than our fan. Speed 3 very quickly clears the room, Cleaned the smell of smoke within 20 minutes. Speed 3, is quite loud. Similar to a hair dryer on low, But it’s fast, so hard to get both quiet and fast. The filters are very easy to access and clean. A green light tells you operational, blue light tells you Ionizer operational, great as an additional deodorizer in the bathroom.

We live in a very dry area with two dogs and this purifier is awesome. Plus, it’s quiet, which is important if you want to keep it in your bedroom or the guest room when people are visiting. Of course, it lets out a bit of air so my dog always wants to lie in front of it, which probably defeats the purpose of purifying the air, but we love it anyway.

This fan is awesome. I have had it for about a month now and still no problems. I use this fan to make white noise for me to sleep at night. In addition to the noise, it cleans my room from dust, which helps with my allergies. I don’t really use the Ionization feature, but it is a nice touch. The only issue that I have is that the base is a little narrow and while on thick carpet it tends to fall over if bumped. For hard floors, this will not be an issue. Other than that small issue, this fan is perfect.

After living in my dorm for a few weeks, I developed some throat irritation. I figured it had to do with the fact that there is no ventilation (except for hallway vents/windows). Since purchasing this air filter, my problem has gone away, the room smells better, and there’s been less dust (I’ve been using the original “all purpose filter”- the freshening effect only works for about a week, but the filter is still fine).

This has also helped with my allergies (and my roommates). Case in point- I had the windows open one day, and after closing them, I didn’t turn on the air filter. The following morning, we both awoke with horrible sneezing. The next day, I had the windows closed and the fan on. The following morning was symptom-free.

The fan has three-speed settings. 1 and 2 are very quiet and don’t circulate air very well. They’re mostly just for “quiet” marketing. Setting 3 produces more noise (though you could sleep with it on), and the air stream can be felt a good 7 feet away.

There is also an optional ionizer, which is nice if you either don’t need it or worry about ozone. I’ve also read some reviews that said it caused a lot of dust to cling to the nearby area. The fan itself is about 16in tall, 6in wide, and 8in deep. Good price, size, and so far good quality.

GermGuardian AC4825 Review

GermGuardian AC4825 Review


GermGuardian AC4825 Air Cleaning System shipped quickly and required no other assembly than just plugging it in. The unit is incredibly quiet and even when turned on high, just sounds like a fan is running (or similar to a laptop when the fan turns on to cool it down).

The air seems so much cleaner and purified. It sounds weird, but the air in my son’s room actually smells “cleaner”. I am thinking of ordering a second unit to keep in the main living areas of our home.

However, this unit is so lightweight and easily transported, that I have moved it from room to room. I have noticed a definite difference in my son’s congestion and coughing since purchasing and installing this HEPA filter.

The air actually smells and feels fresh and we both slept incredibly well. It’s very quiet, sleek looking, and Energy Star rated so I don’t have to worry too much about using it 24-7. The air is noticeably cleaner around it and my problem with allergies has decreased because of it.

To test this, I cooked fish last night (our den has an open doorway to the kitchen), and I couldn’t even smell it cooking

I decided to test it again, so I sat on the couch painting my nails. Even using nail polish remover I couldn’t smell it!! It also moves a lot of air b/c even when the ac isn’t blowing air, it feels like it is b/c of this tower! The fan has three speeds. We find the noise level on high to be no more than we experience with our tower computer. When it is set to low, to my ears it is barely audible, and we put it on that speed during the night.

The unit is sleek looking and small, so it looks good in the room and can be carried easily to other rooms as we please.

Germguardian AC4825 also looks great. Just like the picture. Bottom is dark, top is shiny and sleek. It has a UV light that is that blue line in between the top and bottom. While glowing it looks even cooler. The best part is that there is a button that you can press to turn off the light.

I use this at night because I am one that needs a dark room to sleep and can’t stand lights or glowing stuff. So I use the light during the day and shut it off at night.

UPDATE after One Year of Use:

We just about hit the year mark! Still working great and going strong! Make sure you wipe down (inside and out) once a month (as the book says). Still going strong, and working well! =) Buy this one, and you won’t regret it!

Penguin Crane Five Stage Air Purifier Review

Penguin Crane Five Stage Air Purifier Review

Penguin Crane Five Stage Air Purifier

Penguin Crane Five Stage Air Purifier is the best air purifier I can find and at this price you just CANNOT beat it. Works fantastic. Run it overnight and I see a significant decrease in allergy symptoms. This product is so fantastic and the price is great for what is inside.

Comparable models cost $200+. I’ll gladly take a penguin one for that price difference. Filter cost is cheap and available on multiple sites. This unit runs very softly until the filters need changed and even then it really isn’t noisy enough to bother me while sleeping.

Penguin Crane Five Stage Air Purifier is the second one that I’ve bought for my daughter’s room and it does wonders for her room. We live in a slightly older home that acquires a musty smell if nothing is being done to the air, but this purifier really takes care of that. I walk into her room and breathe significantly better each time. There is hardly any dust in her room these days and she has not had the sniffles or allergies at all since we bought it.

This “Penguin” air purifier is so adorable! It works great and the kids think it is so cute. It is very safe to use and will stop working if it falls over due to one of the kids hitting it or running into it. You just have to keep it about three feet from the walls or any other things. It will not work right if you don’t and it will leave a black stain on whatever it is close too. I do not know why this happens, though. All air purifiers seem to be like that.Click here to Check Best Discounted Price for Penguin Crane Five Stage Air Purifier.

We have this and we love it. The filter/UW light keep the air in my kid’s room feeling and smelling fresh and light and judging from the muck that washes out of the filter each time we clean it and the lack of dust in the room I’d say that it does a great job of cleaning the dander/dust/pollen out of the air.

(We keep a very clean home, lots of houseplants, and are non-smokers of course, but we do have 2 cats and tons of trees around the house, so there’s always danger and a LOT of pollen in the air in the spring.)

We always turn it on at night. It also serves as their nightlight. One of the reasons I originally bought it because it had a fan and we needed to drown out some crazy upstairs neighbors so our kids could get some sleep. The gentle white noise coming from the fan still helps hide other household noises and they sleep better overall with it on. We’ve had ours for about 3 years and it still works great.

I wanted a purifier for my office cubicle since my allergies are much worse at work, but I didn’t want something that looked medicinal.

This was the perfect solution! I haven’t been sneezing or using nearly as many issues at work, so I truly think it is helping me. I use it on the low setting when my coworkers are around, but it is pretty quiet. The cute design works well!

Penguin Crane Five Stage Air Purifier is completely adorable and a great size. It fits nicely in a corner in the bedroom, next to the bookcase, and looks even better in person than on screen, which is rare. The dog has grass seed allergies, and the big, powerful window fan blows in a lot of grass seed at the same time that it keeps the room nice and cool. He sleeps in the bedroom and wakes up in the morning itching horribly. Running this penguin on medium all night long results in a dog with no itches in the morning. Definitely, works!

Whirlpool Whispure Air Purifier AP51030K

Whirlpool Whispure Air Purifier, HEPA Air Cleaner, AP51030K

Whirlpool Whispure Air Purifier AP51030K

Whirlpool air cleaners have one of those companies that you know they make a lot of home electronics, but when it comes to looking for air purifiers you don’t even think of them. If this is the case then you are missing out on an extremely good home air purifier for the price. Matter fact, this is my best bang for the buck air purifier. A certain Honeywell air purifier is shortly behind it, but this one just has too much for it. Whirlpool air purifiers pretty much is widely known for this air cleaner and the Whirlpool Whispure 450 air purifier.

The  Whirlpool Whispure Air Purifier 51030k is basically an upscale version of the 450, but in a way that surpasses all others for the price. I am not saying that it uses every technology available to complete clean your house of everything, but for the price you cannot beat it! It is hard to explain many things in text, but I will show you many things about this air purifier below. Then you will see what I am talking about when I state it is the best for the buck.


I will show you all the technologies and ratings in this section. This information is very important for you discovering how to correctly choose quality air purifiers for the right price. You should know exactly what you are getting when you purchase something and I will show you what you need to know within this review.


One of the things I forgot to mention at the beginning is the fact that Consumer Reports has this in their top 20 list for air purifiers. This means a lot since they don’t use technologies like the UV air filter, which kills 99% of bacteria, viruses and mold spores. Of course, this air purifier is one of the best for dust, pollen, smoke and pet dander, which many people need a lot of help with within their homes.

On the outside you see a plastic exterior that could look like every other air purifier out there, but you will know differences in a couple things including the air filter that is within the air cleaner. You’ll notice some cool things like the way the air goes in the front and out the top. This way you can lean it against a wall to save space or to hide your use of an air purifier. You also get a retractable power cord.


Now one of the easiest ways to rate an air purifier is by looking at the Clean Air Delivery Rate (CADR). I have stated this before because a certified team of specialist has come up with this rating and it is written so small on the boxes. Many of the companies don’t want you to look at it. Funny enough Whirlpool isn’t huge either, but it is easier to find on the box. It is rated as 315 overall for (dust, smoke and pollen). Most air purifiers in this price range are unable to reach 300 without the use of 1-2 more technologies in use within the air cleaner.

Dust – 325

Pollen – 400

Smoke – 315

another good things to know about the air cleaners is the fact that you can leave it running while you are not away guilt free. The guilt would be when you get your electricity bill for the month, but since the Whirlpool Whispure Air Purifier is energy star rated you will be energy efficient. I am not saying it doesn’t use energy, but I am saying it uses very little for the amount of power it pushes out.

Control Panel

The controls on this air purifier are quite well made. They have easy to push buttons that are flat to the surface of the air purifier. You will notice some cool features like the carbon air filter and hepa air filter meters. They show you how much life is left in the air filter. It is a pretty good guess, but I like to take a look at it myself. You also have things like sleep mode that put it on lowest fan setting for a period of time. You can even lock the buttons if you have a dog or small children around.

You get 4 fan speeds with the  Whirlpool Whispure Air Purifier. Each one moves a particular amount of air and will make a certain amount of noise to do it. For the most part, the speed will go as high as you need it. As you can see with the CADR it will move plenty fast. It is a pretty quiet air purifier, but it is not quietest. That is why it is always good to only use the highest setting when you are away or need instant air purification.

Fan Speed 1 – 40 decibels

Fan Speed 2 – 43 decibels

Fan Speed 3 – 46 decibels

Fan Speed 4 – 50 decibels

Whirlpool Whispure Air Purifier AP51030K 2

Charcoal Air Filters

As you have probably heard the activated carbon filter is one with the prefilter. The prefilter is just thick media to capture large particles that find their way into the air purifier. They prevent the thicker air filters within (HEPA air filter) from being clogged up too quickly. The best part about these is the fact that you can wash them off with water or even vacuum them.

The activated carbon is used in various environments to remove odors and smells. You may find it in your fish tank or your water filter if you want to look. The important part for us is the fact it does the same thing in the air. If you have stinky trash, smoke or those darn baby diapers smelling up your house this will help considerably with that problem. Of course, there is something you should know. The amount of carbon in the air filter is small and it will run out sometime within 3 months. You cannot wash this clean. Once it is used up you need a new one.

Air Purifier HEPA Filter

My favorite part is the “True” HEPA air filter. When I say true it means it is an actual certified HEPA air filter that meets the qualifications. Many others will be HEPA-type or HEPA-like and they are not as good. True HEPA air filters stop 99.97% of particles down to 0.3 microns in size. If you think that a human hair is 10 microns you can guess how small this is. When you start catching things this small you really start to purify the air effectively. Even better is when you provide enough of this you can get this down to 0.1 microns or more like the IQ Air purifier. Conclusion   The design of this Whirlpool air purifier is pretty simple, but yet it is well made. The combination of the prefilter, carbon filter and true HEPA air filter have made an air cleaner that is hard to beat. Many of other companies sell this combination for money and still don’t meet the CADR ratings. Some people use more or less media and that makes a big difference in the performance of the air filtration. If you are considering a nice home air purifier this will be the one you want if you don’t want to go broke and think you just bought a glorified fan.

Honeywell 17000-S QuietCare True HEPA Air Purifier

Honeywell 17000-S QuietCare True HEPA Air Purifier

Honeywell 17000

For being such a simple machine the Honeywell air purifier 17000 has shown itself to be very popular in the consumer scene. Many people have flocked to this air purifier once they learned about True HEPA air filters and how well they work. The other reason is simply the price compared to other air purifiers that have the same type of air filter. If you look around in some places you will notice them saying this HEPA filter is permanent and cleanable, but it is not exactly true. You may be able to vacuum this and release some of the dirt, but unless you have HEPA vacuum I doubt you will get it very clean since it is meant to trap the dirt and not be cleaned.

The Honeywell 17000 is one of your safe bets if you are short on money, but need some decent air filtration for your home. The price with the great air filter is a win for many people and when they see the deal they jump on it. Besides most people only have small allergic symptoms to pollen and dust anyway and don’t need the super powerful machines. If they have them it would be like night and day. They wouldn’t even want to leave their home!

In this section, I will go over the features of the Honeywell air cleaner. You will be able to see why this air purifier is a good choice for common allergy sufferers. These are people that have allergies, but they are relatively weak; however, they are still bothersome and need to be dealt with. It will also give you some tips on what you might want to purchase if you want to spend just a little bit more money. Construction

The construction of this air purifier is a bit different from the rest of the usual air purifier’s models you see. The general way of making an air purifier is by using a flat surface up front and sucking air through it. Others have used circular air flters that pull in from all sides for efficiency. Even others pull from the floor. Oddly enough this one pulls from the front and blows out the back, but it is still circular. I am not sure how this affects efficiency, but I believe it is one reason it is not up there with the likes of the Whirlpool Whispure 510 air purifier.

You get three fan speeds on this Honeywell air purifier. They are push button and are easy to use. The highest has a good range for a bedroom and the lowest is low enough to sleep through. I know some people like white noise when they sleep and it would be an ok thing for them. They may even want it louder. It seems that noise is a big thing people worry about when it comes to air purifiers because of the power of the fan. I don’t think its a big deal unless it sounds like an airplane going over your house then it probably won’t be a big deal.

You also get air filter regulators that tell you when you need to change your air filter, which is a handy thing. You can try to clean it and see if it helps, but it won’t last for long and will degrade the efficiency of the air filter if this is continued to long. I prefer just to buy a new air filter when it is time to buy a new one. Prefilter   The prefilter is the very popular 38002 series that is made to wrap around the circular air filters like the Honeywell 20500, Honeywell HEPA filter 21500 and the Honeywell HEPA filter 24000. If you have used these prefilters before you will know that they are also pre-cut so you can take it down to a smaller size to fit other models. That is their way of needing so many different products for all their air purifier models. I think it is a very smart thing. You can also try to clean this off a few times before you replace it and it will make a difference somewhat. Air Purifier HEPA Filter

Honeywell 17000 2

The True HEPA air filter used in the Honeywell 17000 is very good for the price of the air purifier. You can look around and see that only a few air cleaners have this type of air filter for this money. After you get past all this you have to think about other things like the prefilter and construction, other technologies and usage. All of these come into play as well in the situation and will determine how well the air filter will work for you.

These “True” HEPA air filters stop 99.97% of particles down to 0.3 microns. This is microscopic and the naked eye is unable to see these super fine particles in you air, but they are there. Most dust and pollen particles are between 0.5 and 4 microns so that gives you a reference point. If you want clean air when you get home it is good to leave this running while you are at work and let it clean the air thoroughly, but you will need more and better versions for bigger spaces. This Honeywell is only capable of about 150 square feet, which is around the size of a decent bedroom.


Honeywell 50250 Air Purifier

Honeywell 50250 Air Purifier

Honeywell 50250 Air Purifier

As far as HEPA air cleaners go this room air purifier is definitely the top choice you can make. Even if you look further it is one of the best air purifiers you can get. Now I am not comparing its apples to apples. It is more like apples to oranges. Many other air cleaners have several technologies in use. This one doesn’t have, but a couple, but they are top of the line, which makes a big difference. The most important part is the fact that is is one of the best air purifiers for a budget. If you don’t have much cash this is this best for you.

I believe the Honeywell 50250 air purifier is an air purifier that everybody needs in one room or another just for controlling air pollutants in areas you frequent a lot within your home. The price is unparalleled for the amount of air filtration you get. You can easily see this by the Clean Air Delivery Rate (CADR). CADR is one of the easiest ways to rate an air purifier and if you don’t see one on the box then you have no business purchasing it.


In this section, you will find information about the technologies and parts and ratings for this air cleaner. This will show you what you are getting for your money and just how good this air purifier is. If you haven’t already learned this from the comments people have posted all over the web then this will reconfirm your previous thoughts of why you should purchase this air purifier.

Construction and Controls

As you can guess this is a plastic air purifier and will not be the best thing to roll down the stairs and expect it to still work once it has bounced into the wall. That doesn’t mean it is not built well and is made to last. I want to focus a bit on the small problems people have complained about with the air purifier. The first is the LED that surrounds the fan speed selector. It is bright at night but is no brighter than a LED clock. Of course, if you do not like too much light in your room there is a way to turn it off. You can find a short picture guide of how to do this below.

The second problem is the sound of the Honeywell 50250 air purifier. It is louder than most air purifier and many people don’t like it that much. Anything above the lowest setting is too much when you are in the room. The low setting is great for white noise while sleeping because it is so much quieter than the second level. The second level is almost as loud as the final and third level. As you can tell this leads to why it has such a high CADR with air movement like that.

Two things that you will probably like if you don’t check the  inside of air purifiers much is the air filter life meters You have one for the carbon air filter and the HEPA air filter. Once the filters become clogged you will see the meter go up until it hits the top and makes the light change colors, which means it is time to change or clean the filter. Fortunately, these are usually lifetime except for the carbon filter, which will run out of useable carbon every 3 months usually.


You can learn a lot by looking at the ratings of things such as Honeywell air purifiers. You can see how much it cleans per square foot, how loud it is and how much energy it uses. All of these things will come into play when you want to choose the best for your home or business. I have labeled these stats below for you to view and I will tell you that I look for CADR levels above 200 in all air purifiers to label them as good enough for my house. I also don’t like the decibels to be above 50 if I am in the room, but that is a personal thing.

Clean Air Delivery Rate (CADR)

Dust – 250

Smoke – 250

Pollen – 250

Noise by Decibels

  • Low – 35 decibels
  • Medium – 45 decibels
  •  High – 57 decibels

Energy Usage

  • Low – 50 watts
  • Medium – 120 watts
  • High – 170 watts

Charcoal Air Filters

The prefilter is actually an activated carbon air filter as well. I really wish that these two things could be separated, but the price is minimal and space is limited as well so many companies opt to put them into one single air filter. As you can see below the air filter is actually a sleeve that wraps around the HEPA air filter with Velcro straps. It is a fairly thick air filter comparing too many I have seen that are actually see through. I believe it is close to the perfect thickness for the charcoal air purifiers and the price that you get to pay for the end product. Its particular name is Honeywell 38002 if you are looking for a replacement air filter.      The large particles in your air will be caught on the prefilter and believe it or not you can vacuum them off. I would prefer you use a HEPA vacuum cleaner to do this so you drop spread dust and pollen all over the place.  You could also just vacuum it outside to stop that problem. You will notice that the carbon will need to be replaced every 3 months or less depending on your air quality. I want you to know that you wash your carbon air filters and expect them to absorb odors and smells again. It is impossible to do this. You have to replace them once they are full. It works the same way when they are used in water filters. Replacement HEPA Filters

The Honeywell 50250 air purifier is unique because it has a circular structure that sucks in air from all sides and blows it out the top where it won’t hit anybody like a sudden breath. That way the air will come back down on you as clean. The most important feature about the Honeywell HEPA filter 24000 is not this fact, though. It is the fact that it is a True HEPA air filter that filters 99.97% of particles down to 0.3 microns in size. This is about 70x smaller than a human hair. Obviously, you cannot see this, but you can rest assured once your breathing gets better and you can sleep through the night without allergy symptoms you will know the difference.

To those that don’t know not all HEPA air filters are built the same. Some are just cheap imitations are usually labeled HEPA-type or HEPA-like. I am not saying they don’t work at all, but they only clean about 90% of particles down to 0.3 microns. That may sound good, but would you buy 90% antibacterial soap? The thing about Honeywell 50250 air purifier True HEPA air filter is the fact that is will last a lifetime because it is reusable. You can actually clean it and use it again. Not many True HEPA air filters are capable doing this. I will state that the performance of this air filter continues to fall each time you clean it and reuse it.  Of course, this cost saving can see in your wallet. If you are more serious about air quality then you would go for a much more powerful machine with thicker air filter media.  Conclusion

As a last thought, I believe that this is a room air purifier that would be best to get rid of your dust, pollen, and pet dander problems. I believe it is good for mild smoke issues if you smoke in the house. I would just make sure you smoke within the 500 square feet of the air cleaner. Everything else will get absorbed quite rapidly with the True HEPA air filter. The price has already lured you in and I can tell you that it is a good buy for the money. You may not
