HEPA air purifiers are the gold standard in air filtration technology to improve indoor air quality. Research shows that true HEPA filters effectively capture 99.97% of airborne particles that are 0.3 microns or larger in size.

How HEPA filters work

HEPA filtration works through an impressive three-stage capture mechanism. The filter uses diffusion to catch particles smaller than 0.1 microns, while interception traps particles that stick to filter fibers. Larger particles embed directly into the fibers through impaction. A pleated design creates a dense mat of randomly arranged fibers that effectively traps particles of different sizes.
