How to Choose an Air Purifier

Pick the right purifier by matching coverage, technology, and daily use to your home and family needs.

  1. Match the Room Size: Measure the room and choose a unit rated to clean that square footage, or one that lists cycles per hour for similar rooms.
  2. Know the Technology: UV-C systems deactivate microbes without filters, while HEPA systems capture particles; consider allergies, odors, and maintenance preferences.
  3. Consider Noise Levels: Look for multiple fan speeds so you can run stronger filtration during the day and quieter modes at night.
  4. Safety Around Kids: Choose enclosed UV systems with no ozone production and follow manufacturer placement and operating instructions.
  5. Placement and Care: Place the unit where air can circulate freely, keep vents clear, and follow recommended cleaning for long term performance.
