Review on 🌬️ Alen FLEX Large Room Air Purifier, Powerful Air Flow, 700 SqFt Coverage, Dust, Pet Dander, and Pollen Air Cleaner, Efficiently Removes Cooking and Smoke Odors, Extended Filter Lifespan by Kelly Porter

First off, let me say that I have had several other air purifiers and am aware of white noise. I bought a bedroom flex after reading about Alena. It arrived today and the packaging was fine. I opened the box, put the filter in place and pocketed it. I turned it on and immediately smelled a chemical smell. Then I noticed that the motor spins up and down slightly at fan speed 2, which makes the device make a very annoying noise. Then I read that the smell is a constant problem. I also learned that Alen filters are not true HEPA. They don't even have a HEPA rating and an AHAM rating. I've already put this junk in a box and am sending it back to Amazon tomorrow. What a waste of $400. Lesson learned I think. You don't get what you pay for with this company. I should also add that I asked the company for help and had to leave a voicemail that hasn't come back yet. Find another reputable company that really is HEPA!
