The Best Company Ever!

Alen is seriously the best company around. I've had an air purifier for 18 years and it recently wasn't working that great and a model that they don't make anymore. Alen sent me a brand new Flex purifier and couldn't be happier. Have a 3 year old baby girl and her health is most important. To know she's got clean air and breathing well means everything. Lifetime guarantee is amazing. Professional, classy company. Thank you so much! Felt the difference the first night with air quality!

Though we have a top of the line furnace & A/C with "all the bells & whistles" we prefer to have another air cleaner in our bedroom. It keeps the air clean & fresh.

I, actually, haven’t installed it yet since the yellow light is still on. I enjoyed the ease of getting it.

Alen BreatheSmart FLEX HEPA Filter is First Rate!

My Alen BreatheSmart FLEX HEPA filter arrived quickly and in excellent condition. The air cleaning is beyond reproach. It makes the rooms feel clean with no dust or contaminates floating in the air. The filters are well made and changing them is very straightforward and simple to do. And an extra bonus is they are reasonably priced.

Not impressed.

Since I received my Alen Purifier one year ago I don't see any noticeable change in the air quality. Additionally, when I went to reorder a new filter, I was shocked at the price of a new filter. Way too much money.
