These are the best air purifiers for dust, based on reviews, certifications, and filtration type. Top picks include Coway, Molekule, and Levoit.

Growing concerns about indoor air pollutants, including dust, smoke, and viruses, have made air purifiers increasingly popular. Not to mention, researchers have found bacteria and carcinogenic compounds in household dust, making air purifiers an attractive option for many people looking to get rid of contaminants in the home.

People with dust mite allergies and other sensitivities to airborne particles might be particularly interested in how an air purifier can help.

Air purifier glossary

  • HEPA: High efficiency particulate air filters, known as HEPA filters, can remove 99.97% of dust particles that are 3 microns in diameter, according to the Environmental Protection Agency (EPA). Air purifiers that have a HEPA filter tend to be the best at filtering out dust from your space. (All purifiers on our list use HEPA filters, except the Molecule Air Mini+.)
  • Energy Star: This is a program run by the EPA. Products that meet the agency’s energy efficiency certifications can display the Energy Star logo.
  • CARB certified: California Air Cleaner Regulation (CARB) is a standard set by the California Air Resources Board. In order to meet this regulation, devices must meet certain limits for how much ozone they produce.
  • CADR: A device’s clean air delivery rate (CADR) is a measure of the volume of filtered air that the device delivers per minute. There are usually different scores for smoke, pollen, and dust. CADR is generally measured in cubic feet per minute (cfm) or cubic meters per minute (cmh).

We chose these air purifiers based on the following criteria:

  • Certifications: We looked to highlight products that have a high CADR rating for dust in particular. We also looked for products that are CARB certified and Energy Star rated.
  • Clinical research: We read dozens of studies on dust filtration using air purifiers to figure out what works best in consumer and health services 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. We also included an option with photoelectrochemical oxidation (PECO) technology.
  • 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 to consider before buying the product.

Air purifiers use a fan-like mechanism to draw 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 via another fan-like mechanism.

Some air purifiers are better at dust control than others, depending on the technology and filter system.

Using air purifiers in smaller, enclosed spaces can also increase their efficiency.

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’re 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 will not 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 to function as a white noise machine while they sleep, while others need an air purifier that’s as silent as possible.

According to the EPA, an air purifier can help reduce airborne contaminants, including viruses. However, it cautions that an air purifier is not enough to protect against COVID-19.

Some manufacturers, like BlueAir and Molekule, have tested their products against COVID-19 with positive results.

A 2022 study found that PECO air purifiers like Molekule may help reduce SARS-CoV-2 molecules. Still, air purifiers should be part of a larger plan to prevent exposure to the coronavirus.

Yes. Air purifiers with a HEPA filter tend to be the best for filtering dust from your space. According to the EPA, HEPA filters can remove 99.97% of dust particles that measure 3 microns in diameter.

There’s no official recommendation to use air purifiers if you have allergies. But air purifiers can help remove airborne particles like dust, dander, pollen, and mold.

Some studies have linked allergy symptom relief with the use of air purifiers. In fact, a 2018 study found that a HEPA air purifier in a bedroom helped with allergic rhinitis symptoms.

Another 2018 study found that air purifiers with PECO filters reduced the participants’ allergy symptoms.

An air purifier should be in a spot where it has space for airflow around the top, front, and sides. Tucking an air purifier behind furniture or beneath a shelf reduces its efficacy. Placing an air purifier on an elevated surface can be a good way to boost efficiency.

Keep in mind that air purifiers have a recommended capacity, so make sure you’re using a version that’s right for the space.

The time it takes an air purifier to clean a room largely depends on the size of the room, the air quality, and the speed or capability of your air purifier. Typically, a small room can be cleaned in about 30 minutes. Larger rooms may take several hours.

For the most effective air purifying, make sure you’re choosing a model that can handle the size of your room. For example, you don’t want an air purifier that’s best for a 250 sq ft office if you’re trying to clean a 1,500 sq ft living space.

If you’re experiencing chronic allergy symptoms, like coughing or sneezing, you likely have some allergens and contaminants hanging around. Regular snoring and frequent illnesses may also suggest that you have irritants in your air.

An air purifier might help if you notice lingering smells, heavy humidity, or visible pet fur tumbleweeds in your home.

If you use chemical-based cleaning products or paint regularly, an air purifier can reduce the smell.

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 and 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 dust control in your space.
