best air purifier no filter review

Air purifiers are a great way to make sure the air you breathe is fresh and clean, but many people are confused about which type of filter is best. There are three types of air filters available for home use, electrostatic, HEPA, and charcoal. HEPA filters are made of an advanced type of cotton fiber that captures particles as small as 0.3 microns in size. Electrostatic filters also work by attracting dust and particles to their surface and holding them there.
