Frequently Asked Questions

What size air purifier do I need?

Match the unit to your room: small bedrooms need coverage around 150–250 sq ft, living rooms 300–500 sq ft, and open-plan spaces 500 sq ft and up. Each deal page lists the manufacturer-rated coverage area.

Do I need a True HEPA filter?

Yes for allergens, smoke and wildfire particulate. True HEPA captures 99.97% of particles down to 0.3 microns; "HEPA-type" and "HEPA-like" filters do not meet that standard. Look for True HEPA in the product description.

Are these air purifier deals actually discounted?

Yes. Every price is compared against that model's own Amazon list price, and we flag units tracked at their lowest price in the last 90 days.

How much do replacement filters cost?

Most True HEPA filters run $20–$70 and need replacing every 6–12 months. Factor that into the total cost — the cheapest unit is often not the cheapest to run.

How often is this air purifier list updated?

Daily. Editors re-verify every price within a 24-hour window and remove expired or out-of-stock units on the next refresh.
