231–249 CFM output pairs with a laser PM2.5 sensor and roughly 23 W turbo draw, low for the airflow delivered. Choose the Smoke Remover cartridge; the standard carbon load underperforms on real smoke.

Its value is measurable: roughly 231–249 CFM, a laser PM2.5 sensor, useful sub-45 dBA airflow and low power. Choose the Smoke Remover cartridge—the standard carbon load is less compelling. The well-executed app is additive rather than mandatory. Cost-cutting appears in the all-plastic body, two-year warranty and all-in-one proprietary filter.
Rigid cylindrical shell keeps the footprint compact and supports 360-degree intake.
AHAM-verified 231 CFM smoke output in the current 400S-P.
The optional cartridge adds materially more adsorbent for smoke and cooking odors.
Low measured power and smooth speed control improve acoustics and longevity.
One of the tidiest cylindrical purifiers: matte finish, small visual footprint, excellent top touch panel and clean AQI display. The app is polished, but every core function remains available on the unit.
Two-year warranty with widely available OEM filters. Motor is efficient, but repair options are limited and the bonded cartridge must be replaced as a unit every six to eight months.
