The Best Air Filter for Dust: HEPA Filters for Clean Air

Are you looking for the best air filter to keep your home free from dust? High-efficiency HEPA air filters are the ideal choice for a standalone air purifier, as they can trap up to 99.97% of air particles. After testing more than 50 air purifiers, we have found that the Coway Airmega AP-1512HH Mighty and the Levoit Vital 200S are the top two options. Both are powerful enough to use in a large room, quiet enough to sleep nearby, designed to last for years, and economical enough to set up in multiple rooms. In conditions where air quality is poor, such as when your area is affected by a nearby wildfire, we recommend running air purifiers at a high temperature for one hour and then running them in a quiet environment or medium to create and maintain clean air in the home.

After burning 15 wooden matches (to create an initial heavy load of fine smoke particles), we tested this method with the Coway Airmega AP-1512HH Mighty and the Airmega 400 for three hours (one hour at high temperature), followed by two at medium temperature. The Coway Airmega is an award-winning air purifier that is one of the most effective units for removing contaminants from medium-sized rooms up to 361 square meters. It has powerful fans under the hood, a sleek design, long-lasting HEPA and activated carbon filters, and a powerful but energy-efficient fan. The digital display is informative and intuitive, providing real-time air quality data in numerical, color, and friendly tagline formats.

It also has eight modes that focus on energy and sound levels, and even one that automatically turns the unit on an hour before bedtime. The flat pack furniture giant IKEA has developed an affordable purifier that will work wonders in small spaces - the FÖRNUFTIG EPA12 filter. Although not equipped with a HEPA filter, like our other recommendations, the EPA12 filter is optimized to capture PM2.5 particles, such as dust and pollen, with a CADR rating of 120 CFM. For those concerned about the efficiency of this purifier without a HEPA filter, don't worry, as the EPA12 filter will still remove 99.5% of particles between 0.1 and 2.5 micrometers, making it perfectly out of reach of dust particles. People with dust mite allergies and other sensitivities to airborne particles may be particularly interested in how an air purifier can help.

According to the EPA, HEPA filters can remove 99.97% of dust particles that measure 3 microns in diameter. This is due to advanced HEPA technology that uses a double air intake and an electrostatic charge to group the particles together. Air purifiers with a HEPA filter are usually the best for filtering dust from your space. Some homes may be more susceptible to dust buildup due to what's inside (such as pets or lots of plush furniture), gaps in old doors or windows, an old climate system, or the local environment as key factors. To keep your home free from dust buildup, it's important to maintain a regular regime for dusting and vacuuming. Purifiers work best in an adjoining space; if you want to clean the air in both rooms at once, you'll need two units or one larger unit with two fans.
