Overview
Drawing air in from all sides, this black tower passes it through a three-layer HEPA and carbon filter. An automatic sensor adjusts the fan, and a sleep mode lowers noise.
Low noise and automatic control suit overnight use. The limitation is that airflow and clean air delivery rate are not in the specs.
Who it's for
Allergy and pet households and wildfire-area homes will use the auto mode. Buyers who compare airflow ratings should check the numbers first.
Pros and cons

Performance notes
Fine particles are caught by the HEPA layer and odors by the carbon layer. The sensor raises fan speed when air quality drops and lowers it when the room is clean.
