Many brands manufacture air purifiers that remove dust particles from the air. They can be suitable for people with asthma and allergy symptoms. These devices come in various sizes, while some have an adjustable fan speed and sleep mode feature to minimize sleep disruptions.

This article explores the benefits of air purifiers for dust, features to look for when choosing a device, and some products available on the market. It also looks at some frequently asked questions.

The Centers for Disease Control and Prevention (CDC) state that low outdoor air quality can be detrimental to health. The organization also says that many people experience exposure to smog and particle pollution.

However, a 2016 article also notes that indoor pollutant levels can be up to 100 times more than outdoor pollutant levels.

One of the harmful pollutants that individuals can find indoors is dust. It comes from dead skin cells, stray particulates, and dust mites, which are major triggers for people with allergies and asthma, according to the American Lung Association.

In addition, one article found that house dust and its components also have associations with respiratory infections, wheezing, and respiratory allergic diseases.

People can improve their indoor air quality by reducing sources of contamination, such as smoking.

However, it is impossible to remove all harmful particles from the air. A 2020 article states that walking around and sitting on furniture can lead to 25% of indoor particulate matter concentrations.

Using air purifiers to remove dust can reduce concentrations of small particles by 30–80%, which offers some of the following health benefits:

When it comes to using air purifiers for dust removal, people should consider the filters they use.

According to the Environmental Protection Agency (EPA), devices with a high-efficiency particulate air (HEPA) filter can remove 99.97% of airborne particles with a size of 0.3 microns. These include dust, pollen, mold, and bacteria.

There are some features to consider when choosing an air purifier for dust:

  • Clean Air Delivery Rate (CADR): Refers to the volume of particles the unit can filter in a set time, and it should match the size of the room where a person will use it.
  • Target use: Some air purifiers work on removing particles, while others focus on gases. People looking for air purifiers for dust control should look for filters that target dust removal specifically.
  • Filters: Some devices feature more than one filter, so a person should check when they should replace them.
  • Fan speed: There are devices featuring fans that adjust their speeds according to the pollutant levels. Their speed also lowers during the night, so the unit does not disturb sleeping people.
