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.

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.

Best Brand

I chose Allen because of my sensitivity to environmental toxins, as well as the stylishly designed air purifier units. The replacement filters are easily ordered, simply replaced, and are delivered expeditiously. Thank you, Allen, for making my life healthier and simpler! Nani Lawrence

Amazing how clean our home smells

We live in central Florida, and our units keep us feeling pollen, dust and aroma free. The HEPA filters are great

TRUE HEPA

Great filter we have 2 breathesmat one upstairs one down. The system is great but filters cost is too high. Friends are switching to other systems for that reason. I will stay another year or so then start the research to switch though I like the units it's hard to justify the cost of replacement filters.

Does the job for me

Filters EZ to order, EZ to install, runs silent. Can select speed and hours. I replace every 12 mos. No animals, and only on during day.
