- How large a room will it actually clean?
- The rated coverage is up to 1,500 sq ft, which assumes open space and a high fan setting. In closed rooms with furniture and doorways, expect effective cleaning over a smaller area, and expect several air changes per hour only at higher speeds.
- Does it remove allergens and smoke?
- It uses a HEPA filter, which captures fine particles such as pollen, dust and pet dander. Smoke particles are also filtered, but gases and odors need an activated carbon layer, which is not listed here.
- Does it have an app or auto mode?
- No. The listed functions are air purification only, with no smart app, air-quality sensor or automatic fan control. You set the fan speed yourself.
- How often do I replace the filter?
- That depends on run hours and how dusty the room is; most HEPA purifiers need a new filter roughly every six to twelve months. Check the filter indicator or inspect it monthly and replace when it looks gray or airflow drops.
- What comes in the box?
- A HEPA filter is included, so the unit is ready to run. Check the listing for the power cord and manual; no remote or extra filters are mentioned.
