While this air purifier is designed for bedrooms, it can tackle areas up to 283 square feet in about 12 minutes, making it a good option for several rooms in your home.

This DREO small room air purifier does a great job of removing duist, smoke, and pollen on low and high speeds. It has a quiet auto mode and a filter indicator, and it's easy to use, clean, and carry. It doubles as a fan and has an app, so you can control it remotely.

DREO’s compact purifier finally brings proper sensing and auto-response to the sub-15K range. With a CADR of 173 m³/h, it works best in bedrooms or study rooms rather than large halls, but the PM2.5 sensor and auto mode make it feel far more intelligent than its price suggests.
