Air Purifiers for Dust and Other Pollutants

Is the air in your home clean? You might think so, but chances are it isn’t as good as you think it is. That’s why air purifiers for dust and other pollutants can make a big difference. Undetectable air pollution is common in many homes for a variety of reasons and it could be affecting you.

First, there’s odors, which are not pollution as such, but they can be unpleasant and embarrassing when someone visits your home. Then there are things such as pollen, mold spores and dust mites which are most likely lurking and you don’t even know it.


Benefits of Air Purifiers for Dust and Pollutants


You probably spend quite a lot of time making sure your house is fresh and clean, don’t you? Of course you do, but it’s the things you can’t see that can be a problem. That bunch of flowers making your room smell nice can give off pollen which can cause eye irritation or bring on an asthma attack to vulnerable people.

Damp humid places like bathrooms and even kitchens can harbor mold, with the spores in the air possibly causing breathing difficulties or lung infection. Dust mites thrive in dust and they can cause skin allergies.

Domestic pets leave their dander around the home, not to mention their smell. Those who suffer with allergies and asthma are particularly at risk from these.

Other odors such as from cooking or smoking can make you home seem dirty no matter how much cleaning you do. Are you now beginning to see the benefits a decent air purifier can bring? All of these problems are dealt with and you can be reassured you’re living in a cleaner environment.

We’ve looked at five popular air cleaners for dust and pollutants below to help you come to a decision as to which one is best for you.

Honeywell HPA300 True HEPA Whole Room Air Purifier


The Honeywell HPA300 True HEPA Whole Room Air Purifier is one of the company’s more popular products, and it has gotten a lot of positive reviews as well. But how does the HPA300 work as far as dust removing is concerned? Let’s take a close look.

Air Purifiers for Dust and Other Pollutants 3



  • This air purifier for dust removal is designed to eliminate airborne contaminants, and it is AHAM CADR Rated 300, allowing it to circulate air five times an hour.
  • The HPA300 has an activated carbon pre-filter which eliminates odors, dust and bacteria in the air.
  • There is an electronic filter and replacement indicator built in as well as a timer which you can set for 2, 4, and 8 hours, perfect for custom use.
  • The HPA300 has three cleaning settings and one for Turbo Cleaning.
  • The HEPA filters on the HPA300 removes up to 99.97% of all microscopic allergens and airborne particles.
  • The HPA300 meets the standards set by the Clean Air Delivery Rate (CADR) Performance as set by the Association of Home Appliance Manufacturers (AHAM).
  • A fan is built into the unit, and it quietly pulls air while filtering and circulating air.
  • Its pre-filter process captures airborne particles, dust and pet dander, at the same time eliminating unpleasant smells.
  • Like other Honeywell air cleaning units, the HPA300 runs quietly.



The HPA300 performs well in removing dust and allergy triggers and it captures microscopic particles as small as 0.3 microns. The HPA300 is best known for removing dust, but it’s also effective for pet odor, smoke, mold spores, cooking smoke and cigarette smoke.

All this is possible because the HPA300 relies on a mechanical filtration system, where a fan draws air in the purifier and subjects it to the HEPA filter. This is done five times on the hour, resulting in cleaner air. Another nice thing about the HPA300 is it doesn’t produce any ozone, a welcome feature if you’ve got breathing issues.

The fact that the HPA300 is so quiet might give you the impression that it isn’t working.  But it does work and even better than others because of its double filtration mechanism. Its design also allows you to place it almost anywhere. If you listen closely it does emit a bit of sound, but it’s best described as just a sort of unobtrusive white noise.

The HPA300 is one of the best air purifiers, but it is not without drawbacks, the biggest is the need to replace the filters. It can be a bit of a hassle, but each one lasts a long time so it’s tolerable.

  • Powerful but quiet
  • Circulates air up to five times an hour
  • 3 cleaning levels and turbo clean
  • For use in larger homes
  • Filters need to be replaced
  • Front cover can sometimes become loose

With a coverage area of up to 465 square feet / 21′ x 22′, it is ideal for large homes and any household that wants to get rid of dust, allergens and keep the air fresh.

Honeywell 50250-S True HEPA Air Purifier


The Honeywell 50250-S True HEPA Air Purifier is often recommended by health experts and physicians. It’s true that Honeywell makes a lot of air cleaning systems, but the 50250-S has features that allow it to stand on its own.

Air Purifiers for Dust and Other Pollutants 5



  • Air purifiers for dust often use HEPA filters that need frequent replacement, but the one on the 50250-S lasts for 3 to 5 years. This makes the purifier less of a hassle to use, and cheaper too. You can also vacuum the filter to further prolong its life.
  • Its HEPA filter is glass fiber and eliminates 99.97% of airborne particles down to 0.3 microns.
  • Like other Honeywell air purifiers, the 50250-S has carbon activated pre-filter to eliminate lint, fur, dust and other house and pet odors.
  • The Intelli-Check Electronic Filter Indicator notifies you when the filter needs to be replaced.
  • This air purifier comes with AHAM certification and a 250 CADR rating for smoke, pollen and dust.

  • Its SurroundSeal technology reduces the possibility of air leaks. Even the slightest leaks affect performance so this is an essential feature.
  • The built-in fan pulls air in, filters them and releases fresh air in 360 degrees. Some air purifiers don’t offer this flexibility so the re-circulated air is distributed unevenly.



The 50250-S works exactly as advertised, removing allergens, microscopic particles, smoke and odors. It’s especially effective for removing cigarette smoke and the smells that come from having dogs and cats running around the house. Compared to other purifiers, the 50250-S works faster and covers more space.

Even if you don’t know the technical details, the 50250-S does what it should as far as   removing dust is concerned. If you do want to know, in simple terms the purifier’s pre-filter is designed to safeguard the filter and soaks in the odors and particles. All of this takes place automatically so when the 50250-S is set, airborne particles are quickly removed.

A word about the filters: use of the odor removing pre-filter is optional. If you decide to use it, replace the pre-filter every 3 months. This is only a general guideline, and you may have to change filters more frequently if someone smokes in your house, if you have pets, or someone has asthma, etc.

The 50250-S is one of the best room air purifiers for allergies, but it is not without shortcomings. It is noisier than other Honeywell air purifiers and it looks a bit drab, but as far as functionality goes it works just fine.

  • Powerful with a good performance
  • Good circulation with 360° air intake and discharge system
  • SurroundSeal Technology prevents leaks
  • Simple maintenance
  • Makes some noise
  • Power consumption is higher than some other models

Air Purifier Buyer’s Guide


Modern homes are far more energy efficient than in the past. One of the problems with this is that, by being better sealed, they trap air pollution inside. Cooking, cleaning, smoking and pet odor, dust, mold and pet dander can all cause problems. This is where an air purifier for dust and other pollution can come in handy.

There are various types available, depending on what you want to do, but those with a HEPA filter are the most popular, so it’s those we recommend. High Efficiency Particulate Arrestance (HEPA) filters have a standard set by the US Department of Energy. They should remove at least 99.97% of airborne particles, 0.3 micrometers in diameter.

Many HEPA filter air purifiers also have pre-filters. These are useful because they remove larger particles like pet hair, before the main filter. They also help to absorb odors and smoke. Pre-filters will typically need replacing regularly, so do bear in mind that ongoing cost, but they do also help to prolong the life of the main filter.

You should take into account the size of your room or home because air purifiers are normally made to deal with a particular size. This can affect the price, but it would be a false economy to buy one which isn’t made to cover the area you need it for.

The air change per hour is something to check, particularly if you’re looking to help manage symptoms like asthma. An air change of four times an hour is better in this situation.

What features do you need? This is down to you, but multiple fan speed and filter change indicators are useful. Do you need portability with wheels or a handle? These can be helpful if you intend to move the unit to different rooms.

It’s important to change the filter according to the manufacturer’s recommendation in order to keep the unit at peak performance. Failure to do so will make the filtration substandard and defeat the reason for having one. It’s a good idea to check the cost of replacement filters as this can make a big difference over time.

Length of warranty is also something to consider. It will, of course, be a limited liability warranty, but the longer the better. A longer warranty is usually an indication of the quality of the unit. Five years is best, but three to five years should mean it’s of decent quality.


Final Checklist

Here’s a list of what you might want to check:

  • Coverage
  • Air change per hour
  • Filter life
  • Clean air delivery rate
  • Noise
  • Energy usage
  • Features
  • Warranty

Air purifiers for dust, pollution and odors can make a big difference to the air quality in your home. This should not only help you to have a clean space, but also a healthier home which wouldn’t be the case without one.
