Allergy Relief Starts with Alen

A Solution as Easy as Breathing

Throughout the year, 50 million Americans slog through some type of allergy agony, according to the CDC. Whether it’s a nagging sniffle or severe symptoms that feel like full-blown sickness, you deserve relief. Especially in your home. After all, we spend 90% of our time indoors. Pick the purifiers that pummel the most allergens.

Filter Out Your Most Aggravating Allergens

Every Alen HEPA filter tackles at least 99% of allergens from dust, dander, and pollen (including weeds and grasses)—particles as small as 0.3 microns. For mold and pet allergy sufferers, our upgraded Silver filters offer even tougher allergy-fighting umph.

*0.3 microns is about 56x smaller than a strand of human hair.
