A large room asks more of an air purifier than a bedroom does. Open living areas, basements and great rooms need a unit with a high airflow figure, and the coverage number on the box is the first thing to compare. Coverage and CADR (clean air delivery rate) figures on these listings are the makers’ own claims.
The six purifiers below span roughly 1,800 to 3,235 square feet of claimed coverage. Sizes, noise levels, controls and filters come from each product’s listing page. We have not used these purifiers ourselves, and every performance figure is the maker’s own.

| Noise level | Lowest-speed dB figures are the maker’s, and high speeds are louder |

Large Room Air Purifier FAQ
How is coverage measured?
Makers state an area for one air change per hour. Treat it as the maker’s figure and check the listing’s fine print.
Does higher CADR mean better?
It means faster air cleaning for the particle type the maker names. Noise, size and filter upkeep still matter.
