The BISSELL Air400 is a console-style HEPA and carbon air purifier rated for rooms up to 485 sq ft, with a CADR of 353 cfm. It has five fan speeds, a particle sensor with an auto mode, a timer, and a display that shows PM2.5 readings. Reviewers find it effective at cutting dust and odors and like the washable pre-filter, but it is bulky and loud at its top speed. It suits people who want strong, sensor-driven filtration for a large living space and don't mind the size.

Owners say the Air400 noticeably reduces dust and odors in large rooms and appreciate the auto mode and air quality display. Common complaints are the size, the noise at high fan speeds, and the cost of replacement filters.
