Better Sleep
Backed by Science

For your best night's rest, pick the only air purifiers proven to improve sleep

The relationship between sleep and wellness is well-known, but more studies now show that air quality can greatly improve sleep. Find out how Alen’s BreatheSmart purifiers support better rest—and the boosted energy, focus, & mood that comes with it. 

Why bedroom air quality matters.

Sleep is your body’s time to rejuvenate. But airborne particles like allergens and pathogens trigger an immune response—disrupting sleep patterns. 

Alen’s antimicrobial medical-grade True HEPA filtration removes 99.99% of those harmful particles and more (down to 0.1 microns).

Sleep is your body’s time to repair and recharge. Airborne particles of dust, mold, dander, and pollen inflame your airways and trigger an immune response—disrupting sleep patterns.
