A HEPA filter is a type of particle filter. Every air purifier has a particle filter, but not all are considered “true HEPA” filters. The specifications are determined by the US Department of Energy and require a minimum efficiency of 99.97 percent when filtering airborne particles of 0.3 microns. HEPA filters can remove dust, pollen, mold and bacteria.
