What's Alen® capturing?

Just regular old dust contains a plethora of irritants that can cause inflammation, increase allergy symptoms, and leave you feeling less than your best. Alen® captures 99.9% of those irritants (even the really tiny ones).

For general allergies and dust, we recommend our Pure Filter – it’s a medical-grade HEPA filter that captures 99.9% of particles in your air as small as 0.1 micron (that means it captures all those allergens and dust particles, even the ones you can’t see).

This HEPA filter is the base for all our filters, but if you have more specific concerns like pet dander or smoke, we have filter options that include extra layers of filtration to address these concerns more specifically.

Pure air for life: the Alen® difference

Alen’s award-winning air purifiers work quietly and efficiently in the background, automatically reacting and adjusting to the air quality in your room to capture 99.9% of particles as small as 0.1 microns.

We are also the only air purifier brand to offer a Forever Guarantee. You read that right—with product registration and regular filter replacement, we guarantee our purifiers for life. That’s a lifetime of pure air that’s perfect for you (or as we like to call it, Utopiair™).

How Alen® filtration works

Our medical-grade HEPA filters work in tandem with our powerful air purifier motors to capture tough, tiny particles for a deeper, more thorough clean. Here’s what that process looks like in more detail:

Step 1

Step 1

Air enters through the large side gills and is pulled evenly through the Alen® filter.

Step 2

Step 2

Alen® filters remove 99.9% of harmful airborne particulates, including viruses, germs, bacteria, dust, and allergens.

Step 3

Step 3

Clean air is released from the purification vents and sent vertically into the space to maximize disbursement of cleaned air.

FAQs

How does an air purifier help with allergies? 

Alen® air purifiers pull the air in your space through medical-grade HEPA filters to capture 99.9% of particles as small as 0.1 micron. That includes things like pollen, dust, and pet dander that can irritate allergy symptoms. 

Where is the best place to position an air purifier for allergies and dust? 

Make sure to select an air purifier that is the right size for your space. Alen® has air purifiers for rooms as small as 700 sq. ft. and as large as 1,300 sq. ft.
You should place your air purifier on your room's longest wall, at least 18 inches away from furniture.

Do air purifiers make the air dry?

No. Air purifiers pull the air in your space through medical-grade HEPA filters to capture 99.9% of particles as small as 0.1 micron. They do not absorb moisture or humidity in the air.

Can I run my air purifier all the time, or should it be used only at certain times? 

We recommend running your air purifier 24/7 for optimal air purification. When set to AUTO, Alen air purifiers adjust their speed to respond quickly to what's in your air.

How often should I replace the filters in my air purifier? 

We recommend replacing your filter every 9-12 months, or every 12-15 months for the BreatheSmart 75i. Depending on your air quality and the level of particulates in your home, you may find you need to replace them more regularly or that they last even longer than estimated.
