Best Air Purifier for Dust Reviews and Buying Guide 2021

Let’s start with news that will surprise and even shock some readers. The cause of many “dust allergies” isn’t dust. It is dust mites. Dust mites feed on dust – particularly dust that is skin particles from people and pets (aka pet dander).

The highly respected Mayo Clinic gives us the cause of “dust allergies.” It states, “Dust also contains the feces and decaying bodies of dust mites, and it's the proteins present in this dust mite ‘debris’ that are the culprit in dust mite allergy.”

All of this is very unpleasant, of course, but the reviews and air purifier buying guide below will be part of a successful solution.

The key to beating a dust allergy (dust mite allergy) is to remove dust from your home with one or more air purifiers and consistent housekeeping.

The cleaning and other tips offered below will reduce the number of dust mites. Keeping dust to a minimum using the air purifiers will reduce the dust mite food source, so they’ll be less likely to repopulate in high numbers.

Note: “Dust” isn’t a technical term. It can be made up of many substances including skin particles, dander, pollen, fabric, soil and yes, dust mites and their feces.

If you believe that pollen, pet dander and other common allergens are part of your allergy issue, then our Best Air Purifiers for Allergies Reviews and Buying Guide with top air purifier models and tips might be useful.

Reviews of the Best Air Purifiers for Dust

More details about features, performance, warranty and ratings are provided in this section.

Note: The ratings are our professional opinion. They are often lower than ratings found on Amazon and other retail sites because we consider the warranty and the long-term durability in our ratings. Many reviewers online don’t factor those important details.

Best for Small Rooms

#1 3-in-1 True HEPA Air Purifier by Air Choice

This affordable air purifier packs a lot of features. It produces ions without also emitting dangerous ozone.

The negatively charged ions bond with dust to make the particles larger and heavier. They are easier to filter out of the air – or they fall to the floor where they can be vacuumed up.

Tip: If you buy this air purifier, also be sure to use a vacuum with a True HEPA filter and mop hard floors with a damp mop rather than just sweeping with a broom to prevent the dust from being stirred back into the air.

Reason it is on the List: Its 3 different ways to filter air will really make a difference in your indoor air quality.

Most helpful user reviews:

Best pro: “The fan is powerful but quiet. The filter was pretty dirty after 1 week. It’s really sucking up the dust!”

Best con: “Mine didn’t work out of the (slightly damaged) box. However, the company was good to replace it. The new unit works fine.”

Room Size: Up to 160 square feet.


  • Sensor monitors dust and pollution and adjusts fan speed to meet the need
  • 3-speed fan
  • Ozone-free ionization reduces airborne particles
  • Simple controls
  • Sleep Mode
  • Light can be turned off

Features Rating: 4 – The rating would be a 5 if it had a timer. There’s no remote either, but for small rooms, a remote isn’t as necessary.

Filter Rating: 5

  • True HEPA, which is the best filter type for dust.
  • Activated carbon pre-filter for odors.
  • Ionizer.

Quality Rating: 5 – Very few of these air purifiers have mechanical issues in the first few years.

Warranty Rating: 3 – The warranty is just 1 year. Most good air purifiers have a warranty of at least 2 years.

Overall Rating: 4.25 out of 5

  • 7 stages of filtration
  • Smart sensor

Guide Section

Dust will always be a factor in your home, partly because much of the dust we see floating around is skin cells we or our pets have shed.

Controlling dust is possible, even quite easy, with a quality air purifier with the right tools.

Do you Have a Dust Allergy?

According to the Mayo Clinic:

Dust mite allergy symptoms caused by inflammation of nasal passages include:

  • Sneezing
  • Runny nose
  • Itchy, red or watery eyes
  • Nasal congestion
  • Itchy nose, roof of mouth or throat
  • Postnasal drip
  • Cough
  • Facial pressure and pain
  • Swollen, blue-colored skin under your eyes
  • In a child, frequent upward rubbing of the nose

Those with asthma might also experience difficulty breathing, chest tightness or pain, wheezing, coughing and shortness of breath.

Your doctor or an allergist will be able to confirm whether you have a dust allergy or other cause of your symptoms.

What Makes a Good Air Purifier for Dust?

Here is a list of filter options and how they help get rid of dust. We rank them in the order of importance for removing dust from the air you’re breathing.

1. True HEPA: As you’ve likely seen during your research, a True HEPA filter must be certified to remove 99.97% of particles .3 microns and larger. For comparison, .3 microns is 118 millionths of an inch. Very tiny.

Most dust is 2-10 microns, easily trapped by a True HEPA filter.

Some brands use the terms “HEPA” and “HEPA-type,” but these are not certified True HEPA and don’t trap as many particles or particles as small.

2. Pre-filter: Mesh plastic and aluminum pre-filters won’t stop small dust particles. But, they will capture large particles like dust clumps and pet fur.

This is useful because a pre-filter stops these large debris from clogging the main True HEPA filter, extending its life.

Here’s the deal: If you want to trap dust, a True HEPA supported by a washable pre-filter are really the only thing you “must” have.

3. Ionizers or Similar

First, if the air purifier you are considering emits ions but doesn’t guarantee it doesn’t also emit ozone, look for another unit.

Ozone will make your symptoms worse!!! If you have asthma, ozone is dangerous.

Ozone is known to harm the cells that line breathing passages. This bulletin from the Environmental Protection Agency is “must” reading for anyone with asthma, severe allergies, COPD or other breathing disease.

OK. Ozone-free ionizers emit negatively charged ions, aka anions, that bond with dust particles in the air.

The new particle is larger, so can be trapped more easily. It is also heavier, so falls to the floor where it can be picked up with a vacuum or damp mop.

4. Activated Carbon (aka Charcoal) filter: The value of an activated carbon or charcoal filter is that it traps odor-causing particles like mold, mold spores, smoke and VOC/chemical vapors. It’s not essential for dust, but useful for general air purifying.


Q: What about UV Light?

A: UV germicidal light kills viruses and bacteria. It might kill dust mite eggs with prolonged exposure. The light has little effect on adult dust mites.

Q: What about antimicrobial filters and coatings?

A: They’re effective in stopping the growth of mold, mildew and germs inside the filter, but don’t impact dust or dust mites.

Q: What about PECO?

A: The unique Molekule air purifier uses photo electrochemical oxidation to destroy mold spores and other organic pollutants. The pre-filter of the Molekule is not True HEPA, so will not trap as much dust and other pollutants.

The PECO filter will destroy dust mite feces.

So, while the Molekule offers some benefits, we did not put it on our list of the top air purifiers for dust removal.

See our Molekule Review and Buying Guide for details.

Useful Air Purifier Features for Controlling Dust

The right filters – True HEPA, washable pre-filter and possibly a non-ozone ionizer are make-or-break for dust air purifiers.

However, these features enhance the performance of any unit.

1. Dust or Air Quality Sensor: These sensors monitor the level of dust, pollen and other allergens and pollutants in the air.

When the level rises or falls, the sensor adjusts the fan to a higher or lower speed.

Here’s what that might look like in a typical home.

  • The dogs come in from rampaging around the dog park and bring in a cloud of dust with them – Boom, the sensor detects the problem, and cranks up the fan.
  • The doors have been open all day to enjoy fresh spring air, and the dust and pollen levels are high. The fan runs at full speed. Then you shut up the house for the night, and within a few hours the excess dust and pollutants are filtered out. The sensor lowers the fan speed accordingly, and the unit runs quieter and more energy-efficiently.

 2. Turbo: Some fans have a Turbo mode that is approx. two times faster than the next level down. It is loud. It is powerful. And it cleans the air very quickly.

Due to the noise level, we recommend running Turbo while you’re out of the room or completely away from the house.

3. A Timer: Most timers can be set up to 8 hours, though a few air purifiers have 12- or 16-hour timers. Set the timer. The unit will do its job and shut off without wasting energy. A timer is especially nice when running Turbo fan mode.

Reducing Dust and Dust Mites in your Home

First, here is a brief list of ways to lower dust levels. Then we’ll tackle the subject of killing dust mites and keeping their population down in the future.

How to Reduce Dust in your Home:

  1. Use a high-quality air purifier: For suggestions, see the list at the top of this page for the Best Air Purifiers for Dust and the reviews that follow.
  2. Choose hard flooring, since carpet harbors dust that is stirred up when walked on or vacuumed with a non-HEPA vac.
  3. Dust from the top down, and then vacuum or damp-mop the flooring.
  4. Unclutter your home, since clutter gives dust so many places to settle.
  5. Vacuum with a machine with a True HEPA filter.
  6. Use a vacuum with bags rather than a bagless model.
  7. If you use a bagless vacuum, always empty the bin outside.
  8. Keep dogs bathed and groomed, (and choose a short-hair breed).
  9. Use air conditioner rather than fans, since fans will pull dust into your home.
  10. Have a no-shoes policy in the house.
  11. Use a high-MERV filter in your furnace. MERV is “minimum efficiency reporting value” is a measure of the filter’s effectiveness in trapping particles. The higher the MERV, the better. But be sure your furnace can take a high-MERV filter. Check with your HVAC technician.

How to Get Rid of Dust Mites:

  1. Get rid of dust – see the List above.
  2. Wash bedding on “Sanitize” mode – the water should be at least 130 degrees F.
  3. Put hypoallergenic dust protectors on the mattress and pillows to keep dust from getting into the fabric. Mites go where the dust is.
  4. Have your upholstery and curtains steam-cleaned to kill dust mites. Carpet too, if you have it.
  5. Lower the humidity in your home using a dehumidifier in summer and a furnace in winter. Keep it under 50%. The reason is that dust mites don’t drink water – they absorb humidity from the air. Lowering the humidity will kill them.
  6. Don’t make your bed. Instead, let it air out because it has absorbed moisture from you during the night, and mites need the moisture.
  7. Freeze stuffed animals (and pillows and bedding if you don’t have a sanitizing clothes washer) to kill mites.
  8. Don’t let pets in the bed. That’s a tough one, but pets shed dander, and mites eat dander.
