The 45i is amazing. It reacts to me lighting a candle in less than a minute from the room next to where it is. It's a distance of 20'. The 45i has made a positive difference in the air quality in my home, and I am grateful!
It's very quiet, works wonderfully. I am very pleased I purchased it. I had black mold in my apartment and because of that I became quite I'll. The Alen 45i gives me so much peace of mind knowing that the air is being purified 24/7.
When I ordered the air purifiers I was concerned about the noise they might produce, our household is sensitive to annoying sounds, I was thrilled at how quiet they were. Love the way they work,love the way they look, love the way they sound!
Our two 45i’s arrived the day we left for a 2 week trip, so just “activated” them today. So far so good, and looking forward to cleaner air inside our home.
My son is allergic to cats. Whenever he comes home to visit, he had to take Benadryl. Even after a deep cleaning. We deep cleaned AND we got the 45i True HEPA Air Purifier and another larger one for the daylight basement where our 2 cats live. He didn't have any allergy problems at all. Great product and quiet!
Game changer for our little family exposed to mould! Sleep quality significantly improved from air quality after purchasing our Allen air purifier - we leave it on all the time for the best benefit and vary the speed depending on presence and time of day! Suoer efficient and user friendly.
