Review on 🌬️ KVV Air Purifiers: Powerful True HEPA Filter for Large Rooms, up to 1700 Sq Ft, Remove Dust, Pollen, Pet Hair, Wildfire Smoke, and Smoker Smell with Quiet Flow by Heather Davis

*** UPDATE: Support contacted me about this situation. The worst customer service I've ever experienced. I have received multiple emails daily from them claiming to be Revain customer service and if I delete or change my review they will give me gift cards as compensation. The man went so far as to say he had a family to support so I would give him a better rating and I hurt their business! In my personal experience, this company buys false positive reviews instead of fixing problems. Please look at other products before making your final decision on what is right for you. Honesty is a big part of my buying process! Everyone has a family to support and you should not be deprived of money because of the company's lies and biased actions! I bought this item for a number of reasons, the main reason I used it in the basement was because I worked throughout the basement. My basement is unfinished and has had a massive cleaning from ceiling to floor leaving a lot of dust, dirt, particles and who knows what else in the air. Surveillance numbers were flawed and did not give exact numbers as they never exceeded 20s. I had a very hard time believing this because of the environment and the amount of particles I was lifting into the air. I then moved this to every room in the house a few times and the numbers never went over 20s. Then I blew smoke straight into the device, placed it in front of a dusty vent, and the numbers never went over 20! It's really impossible to tell if it works, but I have a feeling it didn't really do the job it was made for. I just can't figure out what environment I was in or failed the tests I ran to increase the numbers. This product actually works as expected. The last thing I want is to have a lot of dust, allergens and spores floating around in my basement, house or living environment.
