Rooms up to 540 ft²

Breathe easy in large bedrooms and living rooms up to 540 ft² with industry-recommended 5 air changes per hour (ACH). Completely filters room air every 12 minutes to effectively lower particle levels and create a comfortable home environment. Independently verifide by AHAM for a Clean Air Delivery Rate (CADR) of Smoke/350, Pollen/350, Dust/350.

Customize freely

Easily adapts to your space with multiple color options. Includes two machine-washable fabric pre-filters in Dark Shadow and Diva Blue. Additional colors available.

Remove odors

Remove household odors and gaseous pollutants such as smoke, VOCs, exhaust, smog, odors and airborne chemicals with activated carbon filters.

Simple to place

Some air purifiers have rules for placement, freely place anywhere in the room without compromising performance with the large 360° air intake.

One-button design

Forget about adjusting settings and knobs - a single button controls it all and lets you know when it's time to replace the filter.

Sleep without disruption

Whisper quiet on the lowest speed (32 dB) and equivalent to the noise level of rainfall on the highest setting (56 dB).

Easy filter change

The built-in LED warning system glows red when it's time for a change. For optimal performance, we recommend replacing every 6 months.
