Review on 🌬️ Alen BreatheSmart: 45i vs Flex Air Purifier - Tackle Dust, Mold, Odors & Pet Dander at Home by Karen Rodriguez

BreatheSmart 45i or Flex, True HEPA makes a medium to high pitched box fan sound, it extracts enough dust, dander, fur and anything else floating around in my room 20x18 connected to a kitchen with open views. What I didn't like is that because I also bought replacement filters, I can't get a lifetime warranty on the unit, mostly since I had no idea how well this unit would work and since 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.
