## At a glance

- The listing says it is designed for spaces up to 3,120 sq. ft. with one air change in 60 minutes.
- Pre-filter, activated carbon and HEPA filtration are listed. The manufacturer claims the system reduces 99.97% of 0.3-micron particles.
- Smart Mode adjusts fan speed based on detected room air quality. Eco Mode can switch the fan off after 30 minutes of sustained clean air and restart when pollution is detected.
- Sleep Mode reduces noise and power consumption after the unit detects darkness and clean air for three minutes.

## Pros

- Three filter stages address particles, odors and listed VOCs.
- Automatic Smart, Eco and Sleep modes can adjust operation without requiring constant manual fan changes.
- The listed coverage and 60-minute cleaning claim may suit a large open area, subject to room conditions.

## Cons

- At 24.7 pounds and 22.8 inches high, it is a substantial unit to move or place in a small room.
- The stated coverage is tied to a 60-minute cleaning claim, so it should not be read as a guarantee of identical performance in every room.

## Before you buy

- Coverage is a manufacturer claim for cleaning spaces up to 3,120 sq. ft. in 60 minutes, and filtration results may vary with the room and use conditions. Sleep Mode requires the stated darkness and clean-air detection, while Eco Mode requires 30 minutes of clean air before fan shutoff. The 22 db figure is listed without an operating mode. The listing names a washable pre-filter in the title, while the details list a pre-filter without specifying washability. Confirm the applicable filter care instructions and warranty terms for the selected listing.

## Customer feedback
