For large rooms, we recommend the Koios Home Air Purifier. This is also a great option for anyone looking to purify air in a medium-sized space. The purifier can cover up to 1420 square feet and removes up to 95 percent of allergens, including pet dander and dust mites.
The device has three-speed settings, a timer, an ionizer, and an ultraviolet light that kills germs. There is only one thing it does not have: a built-in air quality monitor. Our recommendation is to get the smaller version of this purifier if you want to monitor your air quality.
It is quieter than most purifiers we tested, making it a good choice for bedrooms. Furthermore, its components are easy to access, making it easy to clean and maintain. It comes with a five-year warranty.
