Incredible Air Purifier
We have 5 pets and without this air purifier I would not be able to breathe, I have to clean off the pre-filter every 2 weeks. The Allen air purifier is an incredible machine in which I run 24/7 and it does a fantastic job keeping our air clean, and I live in the south where it is very dusty and pollen heavy.

    The Alen is outstanding!
    We have had our Alen in two different homes now. In our first home, we had it located in our living room. Allergy seasons in S.W. Florida can be difficult for sufferers. Our home cleared much of that worry away. We are now in rural Colorado, and have located the Arlen in our large bedroom. We called and were able to replace our filter in 3 days with the help of knowledgeable, kind employee who answered the phone. The air is noticeably different than in the rest of the house. We sleep better with no help from antihistamines. Our daughter recommended we get the Alen. She lives in WA State, and loves her Alen too.
      This filter helps me sleep
      This filter helps me sleep due to not getting congested.
        The replacement filter arrived on
        The replacement filter arrived on time and was easy to install. I did, however have to do an online search for how to reset the unit to reflect the new filter. It has been working efficiently for over a year now. I am very satisfied with the quality of this air filter.
          Love these filters
          I love these filters and our purifier. The filter does a great job cleaning the air in the house. Our seasonal allergies are non-existent when using these filters.
            I purchased my Alen air
            I purchased my Alen air purifiers prior to reopening my daycare/preschool in July 2020. I can honestly say we have managed to remain open for the duration! Now I know we have taken other steps to keep our center clean and healthy, but I sincerely believe the Alen system and filters have played a huge part in this. Even during the pandemic our absenteeism for both students and employees has been extremely low. I recommend the Alen products!
              Our air filter has helped
              Our air filter has helped us with better air. My wife use to cough a lot at night .Now she seldom cough at night. The air purifier has helped during pollen season also.
