The 400 HEPA 14 Air Purifier is a large-room air purifier that uses HEPA 14 filtration to capture 99.99% of airborne pollutants, including smoke, pollen, dust, VOCs, and allergens. It covers up to 2,145 sq ft and features smart air quality sensors that enable automatic purification. It suits people who need powerful filtration for open-plan homes or offices. Compared with rivals, its HEPA 14 grade is higher than common HEPA 13, but it lacks smart home connectivity and a washable pre-filter.
