Review on 🌬️ Alen BreatheSmart 45i/Flex Replacement Air Filter - True HEPA Basic Filter for Allergies, Pollen, Dust, Dander, and Fur by Nathan Hutchinson

BreatheSmart 45i or Flex, True HEPA sounds like a box fan Of medium up to high it removed a reasonable amount of dust, dander, fur and whatever else was floating around in my 20 x 18 living room connected to an open kitchen. What I didn't like is that I can't get a lifetime warranty on the unit because I also bought replacement filters, mostly because I had no idea how well this unit would work and because I have 3 dogs and 3 cats , I wanted to make sure I have enough filters when I need them. So when I had to call the office to register my product because the manual entry page wasn't working properly, the very nice and helpful assistant suggested that I wouldn't buy the autoshipping filters if I didn't buy them. You don't get a lifetime warranty, only one year. Each filter has an expected lifespan of 9 months depending on the atmosphere it has to deal with. , according to the assistant, I have about 3 years to reorder, so I don't get a lifetime guarantee. My unit has been running for about 2 weeks now, the filter has picked up a clear layer of dust from my air, and overall I'm happy for now. I chose an air purifier because of what I saw on my indoor cameras at night. There were tiny dots on my camera floating at the top of the ceiling, I didn't want to inhale that dust. Later camera view still shows dust, but not as much, so I'm sure more will be removed over time.
