Pure Air For Life.

What makes Alen different? You. The opposite of one-size-fits-all, our purifiers and filters are thoughtfully designed to fit your lifestyle. But more importantly, we make it simple to address your individual health concerns—from allergies and asthma to pets and pollution. That’s pure air for life. Your life.

Your Concerns. Our Strengths.

Our air quality concerns are as unique as we are. That’s why Alen offers the most customizable line of purifiers and filters available. We make it simple to find the perfect combination based on these common concerns.

Thousands of 5-star reasons
to give Alen a try

“The difference [the Breathesmart 75i and 45i] have made in the air quality is unbelievable. We have pets who shed and it has made a tremendous difference in the amount of hair floating around and on the floors. The air smells so clean.”


- Diane H.

Why Alen?

Best Performance

Class-leading room coverage and efficiency backed by the world’s best customer reviews.

Most Customizable

Purifier models to fit your space paired with specialized filters to address your unique air quality concerns. Plus 14 interchangeable designer panels to suit any style.

Leading Technology

Ultra-advanced features to make your life easier, like the BreatheSmart line’s particle sensor that automatically adjusts for air quality in real-time.

Unmatched Quietness

Clean air shouldn’t cost you peace and quiet. Tuned to produce soothing white and pink noise, Alen purifiers run 2.5x quieter than competitors.

 

Advanced Engineering. Timeless Design.

Step 1

Dirty air enters from behind one of Alen’s exclusive designer panels. Hair and larger particles are immediately trapped by our durable pre-filter

Step 2

Alen’s proprietary filters remove up to 99.97% of harmful airborne pollutants and allergy-causing particles. Antimicrobial coating kills bacteria and fungi while activated carbon leaves air smelling fresh.

Step 4

Clean air exits directly upward with force for even distribution throughout your space

Step 3

An oversized motor quietly pulls air through our filter with exclusive rounded-baffle fan blades, developed by Alen with a former NASA engineer to emit calming white noise as well as pink noise, a frequency shown to improve sleep by 25%.
