In summary, true HEPA filters remove PM2.5 to a great extent, but their real-world efficiency is dependent on where they are and if enough air is moving through them. Look for manufacturers that offer data on the efficiency of their HEPA filter’s specific use to get a firm idea of how well they work. Hope that helps!

A True HEPA filter has been rated to be able to remove 99.97% of particles that are 0.3 micrometers and larger. Be careful with air purifiers that aren’t explicitly stated to have a True HEPA filter. You’ll often see labels like “HEPA-like,” “near-HEPA,” or “HEPA-style.”. Stay away from those.

Do HEPA air purifiers remove PM2.5, you ask. Yes, they do. According to ScienceDirect, HEPA air purifiers can reduce PM 2.5 by 29 percent in settings with very high concentrations. While 29% may not seem like much, it’s significant. And according to the EPA, True HEPA air purifiers actually remove particles smaller than 0.3 microns in diameter better than they do larger ones.
