The official purifier of sleep.

The BreatheSmart 45i is now as quiet as our best-in-class BreatheSmart 75i, and it’s perfectly tuned to generate soothing pink noise for up to 25% better rest. Night mode dims or disables display lighting with one-touch. And according to a SleepScore Labs study, the 45i is proven to improve sleep so you can wake up feeling more refreshed.

Don't Wonder If It's Working. Know It Is.

Auto mode allows our intelligent sensor technology to adjust to your changing environment. LED indicator always lets you know the status of the air quality around you. And when it's bedtime, lights-off mode cleans the air without disturbing your sleep.

Customized for Concern

Our antimicrobial True HEPA filters cover all major concerns: Allergies, dust, mold, bacteria, and VOCs, plus odors from cooking, pets, diapers, and sweaty apparel. Alen’s proprietary antimicrobial treatment kills bacteria and inhibits mold and fungi, while our exclusive nontoxic odor-eliminating technology destroys unwanted smells at the molecular level.

Guaranteed. Forever.

ALEN FOR LIGHT SLEEPERS

BreatheSmart 45i in Luxury Marble

As soothing as a lullaby.

Alen air purifiers do more than clean the air while you drift through your REM cycle. They also sing you to sleep by producing the gentle hum of pink noise: a calming sound frequency scientifically proven to help you sleep up to 25% better. Put restlessness to rest with the tranquil tones and cleaning power of an Alen air purifier.

Start where you sleep.

It’s been estimated that people spend a third of their life in their bedroom, yet most of us don’t sleep well due to allergies, airborne pollutants or sound sensitivity. Bring serenity to your bedside with an Alen BreatheSmart 45i air purifier and the gentle hum of pink noise: a sound frequency that’s lower than white noise and enhances brain activity associated with the deep phases of sleep.

The freshest way to start your day.

In addition to the antimicrobial compound that kills harmful contaminants, the Alen BreatheSmart 45i HEPA-Silver Filter also contains a layer of carbon that absorbs and neutralizes light odors commonly resulting from cleaning products, VOC’s, smoke, cooking, smog, pets and various other household materials, serving you air as fresh as you’ll feel in the morning.
