So happy with my Alen

So happy with my Alen air purifier. Thank you so much

Allergy Relief

I used to start sneezing as soon as I walked into my house. Since my initial Alen purchase, I seldom sneeze anymore. This filter is remarkable. I bought an Alen for the bedroom.

Works great

Love these filters! I cannot believe how much dog hair is trapped when I change them. We have one in every room in the house.

We use these in our

We use these in our three offices as well as home. High quality and very quiet.

Pure Air for Life knows it’s stuff!

The Alen BreatheSmart 45i with HEPA Filter works well, running smoothly and quietly. We expect to get good service out of it for many months. It is worth the cost! The smell in our home is fresh, and the air conditioning spot-on.

Keeps air clean with cats in room

I have this in my bedroom, which I share with my three cats, and it has made a major difference in the air quality, and how I sleep at night. I am prone to asthma, but have had no problems with it since I have been using the purifier. The bedroom is about 12 X 14, and one unit covers it well. Highly recommend.

Great but Expensive

It seems to work pretty well but it's super expensive and I wish there was a way to wash it to prolong it's life so I don't have to buy a replacement every year.

Clean Fresh Breathing!!

These filters work great. The dust in my house is almost non existent and I live on a dirt road. I no longer have a cough! My air cleaner and filters come highly recommended.

Cleans the air as needed.

The auto feature is so sensitive that when I microwave popcorn or am cooking on the stove it detects and ups its game. The air quality indicator goes red and it kicks into high gear to clean the air. The filters last quite a while running 24 / 365. When it requires changing I'm amazed at the amount of material collected on the filter lasting at least nine months.
