Ratings & Reviews for Alen B4-Fresh + Carbon HEPA Air Purifier Filter

Excellent Subscription Mgmt on Filters

Its super easy on auto renewal. YOU don't have to try and remember when to replace, it's all diarized & schedule for you. You can change the filter to be received if you need, and even cancel if you so wish. Super easy & flexible. Having seen what it takes out of the air I am glad we invested in Alen.

Great Products!

We were using Dyson for air purifying. What a joke! Alen Air is the real deal. We purchased the 75i for our main floor and 45i for our bedroom we noticed a great difference in air quality. We have two dogs and having units with pre filters is a game changer. Have recommended their products to family and friends.

Alen Filter

Love how the two units keep the air in our home clean and fresh and love better how easy it is to change the filters at the start of each new year!

Great service

I had a problem with the filter being damaged during shipping. As soon as I notified the company the filter was replaced immediately. The air purifier is great for dust and dog hair. So glad I bought the Alen brand.

Great Result / Great Product

O have had my Alen Breath Smart Flex for a little over a week and run it in my bedroom. It is definitely taking care the air quality!! Less dust for sure but what really surprises me is how much better I sleep because I CAN BREATH!!

Excellent Quality and Customer Service!

Excellent quality! Plus I enjoyed the delivery. Hassle free..

Love this filter

A great filter for our needs on the purifier. Easy to order, quick shipping, and a really good price this time around.

Please include on website that

Please include on website that the 45i filter and flex filter are the same filters. Had I had known - I would have been able to get the bundle but nowhere was it stated that they are the same filters so I had bought them individually instead of being able to get the bundle. Otherwise love the product.

Excellent product

It quietly runs 24/7 keeping the air fresh yet with a touch of a button I can up the level & quickly gives the room a full air cleansing when needed. I have asthma so several years ago when researching for a good purifier Alen was always highly recommended. I have never been disappointed with the product & the excellent customer service.
