Home air filters reduce particles from cooking, pets, and outdoor pollution. Choose between portable HEPA units and whole-house in-duct systems, size by CADR/CFM and ACH, and follow maintenance guidance for best performance.
Independent consumer tests reveal how well air purifiers actually remove particles, how loud they are, and what their operating costs will be. Use CADR, filter type, noise, and safety checks from reputable sources to pick the right unit for your room.
Whole-home air purifiers integrate with HVAC or ductwork to clean air throughout a house. Modern systems combine multi-stage filtration, quieter fans, and smart controls to reduce particles, allergens, and some gases while requiring regular maintenance and proper selection.
Practical guidance on choosing a portable air purifier: pick a True HEPA unit sized for your room, consider activated carbon for odors, check CADR and filter costs, and weigh portable versus whole-house options.
