Our Methodology

We test each air purifier in a sealed 250 sq ft room with a particle counter, measuring PM2.5 reduction over 1 hour. We measure noise at low/medium/high with a calibrated SPL meter, calculate annual filter costs, and evaluate smart features and build quality. No manufacturer has editorial influence.

Frequently Asked Questions

What size room can an air purifier cover?

Room coverage varies by model. Small purifiers handle 150–200 sq ft, medium units cover 300–400 sq ft, and large purifiers can clean 800–1,500+ sq ft. Check the manufacturer's square footage rating and CADR to match a purifier to your room size.

How often should I replace air purifier filters?

Most HEPA filters last 6–12 months with regular use. Pre-filters may be washable and reusable. Check your unit's filter indicator or manual for specific replacement intervals. Running the purifier 24/7 or in dusty environments may require more frequent changes.

Do air purifiers help with allergies?

Yes. Air purifiers with True HEPA or HEPA-type filters capture pollen, dust mites, pet dander, and other allergens. For best results, run the purifier continuously, choose a unit sized for your room, and keep doors and windows closed during high-pollen seasons.
