Air purifiers are devices that help clean the air you breathe in your home. Mounting concerns about indoor air pollutants, from dust to smoke to viruses, have made air purifiers increasingly popular. People with dust mite allergies and other sensitivities to airborne particles might be particularly interested in how an air purifier can help.

Some air purifiers are better at dust control than others, depending on the technology and filter system. We took a look at some of the best air purifiers for dust to see which products live up to their claims.

Any fine particles of matter can be called “dust.” It’s a broad definition that can include particles of soil, sand, pollutants, and skin. When it comes to dust particles in your home, the majority of dust is made up of dead skin cells, hair particles, clothing fibers, and bits of dirt.

Just because household dust is made of mostly organic materials doesn’t mean that it’s a good idea for you to breathe it constantly. Researchers have found everything from bacteria to carcinogenic compounds in household dust.

Enter the air purifier: a fan-like mechanism that draws air in and through at least one filter. The filter attracts and traps dust and other pollutants, thus “cleaning” your air. The filtered air is then released back into your space through another fan-like mechanism.

High efficiency particulate air filters, known as HEPA filters, are able to remove 99.97 percent of dust particles that are 3 microns in diameter, according to the Environmental Protection Agency.

As of now, air purifiers that have a HEPA filter tend to be the best at filtering out dust from your space. Using air purifiers in smaller, enclosed spaces can increase how effective they are.

Other filter technologies don’t work as well for dust filtration. For example, UV filters that zap mold spores and bacteria are also popular, but those types aren’t as successful at trapping airborne dust. Some air purifiers take a “why not both?” approach and combine HEPA filters with UV filters or other types of filters.

We chose these air purifiers based on the following criteria:

  • Certifications. We looked to highlight products that have a high Clean Air Delivery Rate (CADR) rating for dust in particular. We also looked for products that are verified and certified by the Association of Home Appliance Manufacturers (AHAM) and California Air Resources Board (CARB).
  • Clinical research. We read dozens of studies on dust filtration using air purifiers to figure out what works best in consumer and health provider settings.
  • Type of filtration. None of these air purifiers are ionizers, which create a small amount of ozone. Instead, we focused on HEPA filters. In some cases, we highlighted products that combine HEPA with other filtration technologies.
  • Customer reviews and feedback. We looked through hundreds of reviews to determine what customers liked about these products, and to alert you of any red flags that you may want to consider before buying the product.

Air purifier prices can vary widely. Prices are estimated based on the following pricing key:

  • $ = under $200
  • $$ = $200–$400
  • $$$ = over $400

Best air purifier for dust overall

Coway Mighty Air Purifier with True HEPA and Eco Mode

  • Price: $$
  • Energy Star certified and CARB certified
  • Product details: The Coway is equipped with a four-stage filtration system. It starts with a washable prefilter meant to trap bigger dust and proceeds to a HEPA filter to catch the rest. There’s also a deodorizing filter to make your air smell cleaner and a final filter that reduces particles in your air. An automatically eco-friendly mode switches on when there are no dust particles detected in your air.
  • Customer callouts: It’s a bit pricey, but people love the Coway Mighty. Over 12,000 Amazon customers have reviewed this product, with an average star rating of 4.7 out of 5. That’s pretty impressive. What’s more, review aggregator ReviewMeta found that 4.7 rating to be pretty authentic and most of the reviews to be from verified customers. Note also that the “Vital Ion” filter is not an ionizer, so you don’t have to worry about breathing ionized air.

Best air purifier to control dust in larger rooms

Blueair Blue Pure 211+

  • Price: $$
  • Energy Star certified and CARB certified
  • Product details: The Blueair Blue Pure 211+ can control dust in rooms up to 540 square feet (sq. ft.). There are three filters to capture particles: a washable prefilter for bigger particles, an inner particle filter that uses HEPA technology, and a carbon filter that traps gases and smoke. It runs quietly compared to competitors and turns on easily with one-button control.
  • Customer callouts: Some customers say that they can smell the carbon filter, and they don’t always like the smell. If you register the product with Blueair, you get a 2-year warranty free of charge. Reviews on TrustPilot warn that customers aren’t always thrilled with Blueair’s customer service.

Best budget pick for dust control

Levoit Core 300 Air Purifier

  • Price: $
  • Energy Star certified and CARB certified
  • Product details: The Levoit Core 300 works with a prefilter, a HEPA filter, and a carbon filter to trap dust and other irritants. Translation: This model provides similar tech to much more expensive options at half the cost. It even comes with a 2-year warranty.
  • Customer callouts: This air purifier is best in a smaller space, around 200 sq. ft. Many reviewers were especially impressed with how quiet the unit is. Other reviewers noted that the unit seemed ill-equipped to really filter smoke, gases, and scents, so the carbon technology might not be up to par with pricier models.

Best air purifier for dust and odor control

Winix AM-90 Wi-Fi Air Purifier

  • Price: $
  • Energy Star certified and CARB certified
  • Product details: The Winix AM-90 can service a room that’s 360 sq. ft. It uses a prefilter, a HEPA filter, and an activated carbon filter. After being filtered, air is blasted with a special technology meant to break apart smells and gases and neutralize bacteria before it is released back into your space. Filters last for 12 months, and the device comes with a 2-year warranty.
  • Customer callouts: Reviewers noted that while the app works well, the integration with other smart home devices (such as Amazon Echo) is not always so seamless. This disappointed customers who hoped to be able to use Wi-Fi to turn the device on and off.

Best air purifier for dust and allergies

Coway Airmega Smart Purifier

  • Price: $$$
  • Energy Star certified and CARB certified
  • Product details: The Airmega is a splurge, but it does provide powerful dust filtration for spaces up to 1,560 sq. ft. This unit combines HEPA filtration with carbon filtration, as well as a prefilter to capture larger dust particles. There are a ton of different fan speed options and mode settings, as well as automatic sensors that choose mode and fan speed for you based on your current air quality.
  • Customer callouts: Despite the price, the product is only fully guaranteed for 1 year against internal malfunctions. The purifier also has a bigger floor footprint than many other models, since it takes in air from both sides and expels clean air out of the top fan, which means that you can’t put any furniture that would block the air intake next to it on either side. This purifier is designed to be used in larger spaces, though, so keep that in mind.

When you’re shopping for an air filter, there are a few things to keep in mind to make it easier:

  • Energy use. Some air filters are more energy efficient than others. Buying an air purifier that’s Energy Star certified isn’t just better for the environment, it’s better for your electric bill, too.
  • Filtration system. Different filters are meant to accomplish different goals. Purifiers that have a UV filter are great for killing viruses and bacteria, but don’t filter dust as well as HEPA filters. Look into the filter technology before you buy.
  • Filter replacement cost. While you’re looking at the type of filter, check on what it’s going to cost to replace the filters and how often they are going to need a replacement. Some companies will void their warranty if you use anything besides their brand-name filters, so keep that in mind, too.
  • Space. Even the most powerful air purifiers won’t be effective if they’re placed in a space that’s larger than their recommended capacity. Air purifiers typically market the maximum size room that they can handle efficiently, so don’t try to stretch it.
  • Noise concerns. As you research different products, take note of reviews that mention how loud the devices are. Some people like their air purifier on as a sort of white noise machine in the background as they sleep, while others need an air purifier is as silent as possible.

Air purifiers make a lot of hefty claims in terms of what they can do for allergies and asthma. Finding an air purifier that uses a HEPA filter as well as a prefilter is probably your best starting point for finding something that works well.

Consider other concerns, such as noise level, energy use, and how often the filters need to be replaced when you’re looking for a dust control solution for your space.
