Best Air Purifiers for Dust Reviewed 2017 – Buying Guide

dust-purifierDesert dwellers are not the only ones who have to deal with dust, although they get more of it for sure. Dust is everywhere and depending on where you live, you may not even know it’s there until you run your fingers through your furniture or until you suffer allergy attacks.

Dust is a common and ever-present air pollutant. Being indoors does not keep you from it. Fact: Did you know that indoor air is more highly polluted than the air we breathe outside? You might be breathing in other things like pet dander, mold, paint, and other chemical traces found in your house. To relieve your allergies and to keep your indoor air clean, invest in an air purifier. If dust is your particular problem, then purchase an air purifier that has dust filtering.

Generally, most purifiers would filter out different kinds of air pollutants. But before you go out to buy, remember that the type of purifier you get has to meet the HEPA gold standard. The HEPA standard simply means that the purifier you’re using can filter out 99.97% of particles that are 0.3 microns in size. Just how big are 0.3 microns?

Measuring Microns

One micron is a millionth of a meter. That’s pretty tiny. It’s a few hundred times smaller than the diameter of one strand of hair. A smoke particle would be 0.3 microns, so if you find an air purifier that uses HEPA filters, it could also filter out smoke residue. Dust particles would be around 0.2 to 0.25 microns in size.

So, the HEPA standard matters and you should care about it when choosing your air purifier. Otherwise, some random brand won’t alleviate your dust problem. We’ve done some digging and found good quality air purifiers that you might like.

Make sure you get a purifier with a True Hepa filter and not a Hepa type filter.  Hepa type filters only filter 99%, while True Hepa filters do 99.7%.


The Top 2 Purifiers For Getting Rid of Dust

Honeywell 50250-S True HEPA Air Purifier

Honeywell is a leading manufacturer of electronics and appliances. It’s a brand that’s been around for a while and you know you can rely on. They have a broad range of air purifiers, and the 50250-S model is one that you should consider.

The Honeywell 50250-S uses HEPA filters that last between 3-5 years depending on use, and if you vacuum it regularly. It has a CADR rating of 250 each for dust, pollen, and smoke. A CADR rating helps you calculate how much area the purifier can clean out. Here’s a simple formula: CADR rating x 1.5 (that’s in in sq. ft.) = room space cleaning capacity. So if we take 250 x 1.5 sq. ft., that’s 375 sq. ft. that the 50250-S can effectively clean. Of course, you can still place this in rooms larger than this but expect that it would take longer for the purifier to clean the air.

There’s no need to worry about forgetting to replace your filters or over-replacing them. This model has an electronic indicator that will tell you when you have to change or just clean your filters. It’s compact and can be moved around the house. Purchase the 502050-S for its efficiency and price, but not if you’re looking for something with a sleek design or the quietest modes. Admittedly, even at the lowest setting, you can still hear the airflow. But is it annoying? This would be relative to your tolerance and where you decide to place the purifier. Would we still recommend this purifier? Absolutely. It will filter dust, pollen, lint, and pet dander. Clean out the filters when it’s time to keep them lasting longer.

For the price and efficiency, this one’s a winner.



Coway AP-1512HH Mighty Air Purifier

Those with a preference for modern design might like Coway’s AP-1512HH model. It resembles a small speaker (or an Apple product) so if you want a more stylish-looking purifier than the 50250-S, this Coway model is for you. It features a 4-stage filtration system including a pre-filter, a carbon filter, True HEPA filter, and an ionizer. It is also compact with easy-to-use controls and indicators. You can set the purifier to work automatically or put it in Eco mode. If you choose Eco, the fan stops working after 30 minutes of not sensing any pollutants.

The pre-filter is washable, and it is perfect for catching dust and pet hair. The True HEPA filter is where the magic happens—it traps dust, pet dander, smoke particles, and allergens such as pollen. A distinct feature of the Mighty Air Purifier is its ionizing option. Ionizers use negative ionization to bind air particulates. For purifiers that have it, ionizers attract particles in the air for extra cleaning power, often to remove airborne germs. It is important to note that ions are not the same as ozone.

Ozone and Ions

Some manufacturers still make ozone generators as air purifiers. Ozone is a highly dangerous gas and respiratory irritant. While it may kill bacteria in the air, that same amount would be lethal to humans and pets. Ionizers operate like ozone generators in that it reduces static in electronic devices, and its goal is to eliminate airborne bacteria and viruses. However, ionizers are not primarily ozone generators. Ozone generators use UV light while ionizers use charged plates to attract particulates.

Now the question is, do you need ionizers in your purifier? Because ionizers still produce trace amounts of ozone, you may do well without it. True HEPA filters should be sufficient to clean your air.


Between the two purifiers we listed above, the Honeywell 50250-S model should do a swell job at making your air quality better, for cheaper. Honeywell is a company you can trust with all its certifications and recommendations from both consumers and medical professionals. Coway’s Mighty Air Purifier is still a great product, and you can get it for its aesthetics, washable filter, and automatic features. It also operates more quietly than the 50250-S. The ionizer is an optional feature that you may not need, especially if you or your loved ones are especially sensitive to ozone. If you’re looking for cost-efficiency and reliability, choose Honeywell. If you want to upgrade, the Mighty Air Purifier is also worth looking into.
