Buying Guide: How to Choose Air Purifiers

Consider your needs, budget, and preferred features when choosing.

How to Choose

Start with room size—this determines the CADR rating you need. Check noise levels if using in bedrooms (under 35dB is whisper-quiet). Consider filter costs over 5 years—sometimes cheaper units cost more long-term. Smart features like auto mode and air quality displays add convenience but aren't essential for performance.

Common Mistakes to Avoid

  • Buying too small—undersized purifiers can't keep up with air volume
  • Ignoring CADR ratings—marketing claims don't equal performance
  • Forgetting filter costs—calculate 5-year total cost of ownership
  • Placing incorrectly—purifiers need clearance and central placement
  • Expecting instant results—full room air cycling takes 15-30 minutes

Maintenance Tips

  • Clean or replace pre-filters monthly to extend HEPA life
  • Replace HEPA filters per manufacturer schedule (usually 6-12 months)
  • Wipe exterior and sensors with a dry cloth weekly
  • Vacuum intake grilles to prevent dust buildup
  • Reset filter indicators after replacement
