A good air purifier removes these harmful substances, creating a healthier living space for you and your loved ones.Understanding Air Filter Types<ul> <li>HEPAFilters: High-Efficiency Particulate Air (HEPA) filters are the gold standard. They capture 99.97% of particles as small as 0.3 microns and excel at removing dust, pollen, and most allergens.</li> <li>Activated CarbonFilters: These are effective for removing odors, smoke, and chemical fumes. Carbon filters absorb gases and VOCs that HEPA filters cannot catch.</li> <li>UV-C Light: Some purifiers come with UV-C technology that kills bacteria, viruses, and mold spores, adding an extra layer of protection.</li> <li>Ionizers: These release charged particles that stick to airborne contaminants, making them heavier so they fall or attach to surfaces.</li> </ul>Key Ratings to Consider<ul> <li>CADR (Clean Air Delivery Rate): This measures how quickly a purifier cleans the air. Higher numbers mean faster purification.</li> <li>ACH (Air Changes per Hour): This indicates how many times the unit filters the entire room’s volume in an hour. Aim for 4-5 ACH for the best results.</li> <li>Room Coverage: Always choose a purifier rated for a space slightly larger than your room size to ensure maximum efficiency.</li> </ul>Top Air Purifier BrandsAirDoctor is our top recommendation.
