Filtration Technology
Look for true HEPA filters that capture at least 99.97% of particles down to 0.3 microns or smaller. Some models include HEPA H13 filters for finer particle removal. UV-C light adds germ-killing benefits but is optional.
Room Size and Coverage
Match the purifier’s coverage area to your room size for effective air cleaning. Larger rooms require higher CADR ratings and more powerful airflow. Small purifiers suit bedrooms or offices.
Noise Levels
Consider noise output, especially for bedrooms or workspaces. Models with ultra-quiet modes or brushless motors offer quieter operation. Some purifiers produce white noise that can aid sleep.
Additional Features
Features like activated carbon filters reduce odors, while child locks and timers add convenience. Night lights or projectors can be useful for kids’ rooms. Check for certifications like CARB and Energy Star.
