Quick Buying Guide — Air Purifiers

  • Room size: Match the purifier to your room size. Small rooms (up to 200 sq ft) need lower CADR. Large rooms (500+ sq ft) require higher airflow (300+ CFM).
  • Filter type: True HEPA (H13/H14) captures 99.97% of particles including allergens, dust, and pet dander. Add activated carbon for odors and VOCs.
  • CADR rating: Clean Air Delivery Rate measures effectiveness. Higher is better. Aim for 2/3 of room size minimum (e.g., 200 CFM for 300 sq ft room).
  • Noise level: Check decibel ratings if using in bedroom. Sleep mode should be under 30dB. Most purifiers are louder on high speed.
  • Running costs: Factor in replacement filter costs (every 6-12 months). HEPA filters typically cost $30-80 per set.
  • Smart features: WiFi models let you monitor air quality and control remotely. Voice control works with Alexa/Google Home.
