Air purifiers remove dust particles from the air, making them good options for people with asthma and allergy symptoms. Although more expensive, the best options will have several filters and work quietly.

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

While people can improve their indoor air quality, removing all harmful particles from the air is impossible. Just walking around the home 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%. This leads to the following health benefits:

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

According to the 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.

Learn more about HEPA air purifiers.

Other features to consider when choosing an air purifier for dust include:

  • 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: Some devices feature fans that adjust their speeds according to the pollutant levels. Their speed also lowers at night, so the unit does not disturb sleep.

The Centers for Disease Control and Prevention (CDC) states that low outdoor air quality can be detrimental to health. While outdoor air quality has improved in the last 20 years, wildfire and particle pollution still pose a threat to American health.

However, indoor air quality may be worse than outdoor air quality.

Dust is one of the harmful pollutants people can find indoors. Dead skin cells, stray particulates, and dust mites form dust. According to the American Lung Association, these particles are major triggers for people with allergies and asthma.

Dust can also affect people who do not have allergies or asthma. House dust and its components may also contribute to respiratory infections, wheezing, and allergic respiratory diseases.

The Environmental Protection Agency (EPA) states that while air purifiers cannot remove all the air pollutants in a person’s home, they can improve air quality. All air purifiers can remove particles from the air, and the more expensive ones can remove particles and gas.

People should choose air purifiers with an activated carbon filter and a longer running time for the best results. It is also important to only purchase air purifiers the right size for the room where they will operate.

People may also find that removing sources of indoor air pollution alongside running an air purifier will improve air quality. Stopping smoking indoors and ventilating the area with fresh air are just two ways a person can improve the air quality in their home.

While air purifiers can improve the air quality in the home, there are some risks.

People should avoid air purifiers that produce ozone, which can irritate the lungs.

Bipolar ionization technology may produce ozone. However, air purifiers that meet UL 2998 standard certification do not produce ozone.

All air purifiers will need cleaning and filter changes on a regular basis to be as effective and safe as possible.

The following are common questions and answers about air purifiers for dust.

What do air purifiers do?

According to the EPA, air purifiers draw in air through one or more filters to capture particles that may come from dust, tobacco smoke, or pet dander.

Do air purifiers work for dust?

The EPA states that many air purifiers for dust can remove particles from the rooms where people place them. The devices need to be compatible with the size of the room for them to be effective.

Do air purifiers help with allergies?

A 2018 guide shows that HEPA air cleaners can be effective in reducing allergy or asthma symptoms.

However, these improvements may not benefit all respiratory symptoms.

Is an air purifier worth the price?

According to Consumer Reports, air purifiers are expensive, with recommended models generally costing $200-900.

A person should also consider filter replacements, which can cost around $90–175 per year. Additionally, the annual energy cost of running an air purifier may range from around $30 to almost $90.

In addition, some units can be noisy and cause sleep disruptions.

Do air purifiers protect against COVID-19?

According to the EPA, some air purifiers can protect against COVID-19. Look for units that:

  • clean air quickly enough for the size of the room where they will work
  • can clean smoke, pollen, or dust
  • remove airborne particles as small as 0.1-1um
  • use High Efficiency Particulate Air (HEPA) filters

How do I get rid of dust in the air in my house?

Frequent dusting, sweeping, mopping, and vacuuming can help reduce levels of dust in the air. People can also change and wash bedding regularly.

Air purifiers can also help remove dust from the air. The EPA writes that air purifiers with HEPA filters can remove 99.97% of airborne particles.

Air purifiers can be effective in removing dust indoors and improving asthma and allergy symptoms.

They come with different filters, but studies show that HEPA filters can remove most airborne particles, including pollen, mold, and bacteria.

A person should also choose a device compatible with their room size.
