Overview
Pet owners and parents dealing with litter box, diaper and cooking smells get an odor HEPA filter paired with a large fan. A laser particle sensor adjusts fan speed on its own, and color coded rings and the Alen Air app show the air quality.
Big open spaces are what the fan and filter are sized for, with automatic speed changes driven by the sensor. The coverage figure differs between the bullets and the description, and the warranty depends on a filter subscription or proof of regular purchases.
Who it's for
Living rooms, open concept spaces and homes with pets benefit from a high airflow unit that reacts to particles on its own. Renters with one small room will be paying for capacity they do not use.
Pros and cons
- Odor filter targets household smells
- Auto speed from a laser sensor
- App shows trends and remote control
- CARB and Energy Star certified
- Warranty tied to ongoing filter purchases
- Coverage figure differs within the listing
- Heavy, large floor unit
Performance notes
Cleaning speed comes from how much air the fan moves through the HEPA filter, and the sensor raises the fan when particle counts rise. Odor control depends on the odor layer of the filter, which wears out with use, so filter freshness governs results over time.
