I recently retired from TX to CO and our new home has radiant floor heat with no A/C. Our house in TX had HEPA filters in the attic and we also used allergen pleated filters in the air return so I never experienced allergies from our 2 dogs and 2 cats. At the CO house despite regular dusting, vacuuming and steam mopping the ceramic floors I was constantly sneezing and had itchy eyes only inside the house. Taking daily antihistamines wasn't the best solution fro me. To test if an air purifier might help I ordered the Alen BreatheSmart 45i for the bedroom and after 1 day of use I could sleep and wake-up without having sneezing fits. I subsequently ordered 2 more 45i models and a 75i model for the rest of the house. The air purifiers have made a huge improvement with my pet allergies, I highly recommend the Alen air purifiers.
I finally feel like I'm breathing deeply and not worrying about what I'm breathing! This is in a bedroom with an attached bathroom, and we had a mold problem. But not anymore - this unit is doing an amazing job!!
Absolutely love it. These folks got this all figured out. 100 times better than my last air Purifer. I really like the auto mode. My last Purifer I had to clean every month, it was a lot of work. This one you vacuum pre filter when it needs it and change filter ounce a year. I also like the lifetime warranty if you add the filter plan ounce a year.
