An air purifier with a true HEPA filter captures dust, pollen, pet dander and smoke particles from the air in a room. LEVOIT, Coway and Blueair are the three brands that come up in almost every recommendation, and all of them have frequent Amazon deals.
The right one depends mostly on the size of the room and how much you care about noise and filter costs.

How to size an air purifier
Look at the CADR (clean air delivery rate) and the recommended room size on the box. For allergies, choose a purifier rated for a bigger room than yours, so it can clean the air several times an hour on a quieter speed.
Factor in the filter. Replacement filters are the main running cost. Check the price and how often the brand recommends replacing them, usually every six to twelve months.
Our verdict
For a bedroom, the LEVOIT Core 300 is the best value. For a living room or allergy season, the Coway Mighty is the proven all-rounder. For a large open space, the Blueair 211i Max moves the most air quietly.
Frequently asked questions
Do air purifiers help with allergies?
A purifier with a HEPA filter removes airborne pollen, dust and pet dander, which can reduce allergy symptoms indoors. It works best with doors and windows closed.
Should I run an air purifier all the time?
Yes, on a low or auto setting. Air quality changes constantly, and running continuously keeps particle levels low.
Do air purifiers remove smoke?
HEPA filters capture smoke particles and carbon filters help with odors. For wildfire smoke, pick a purifier rated for a larger room than yours.
Specs and features come from the manufacturers and can change between versions. Prices change often on Amazon, so check the current price and the exact model before you buy.
