I originally bought a ~$50 other product for my recently renovated room, but it does not work well. I'm a long time Amazon customer and this is the first negative review I've ever written, I was convinced that our new Blue Air would help my extreme seasonal allergies but I have...Quiet, effective, simple design. I have had it for a few months in constant use and it works wonderfully. I have no more breathing problems so it must clean the air pretty well. I felt the difference immediately. The air feels clear and smells fresh when it's running.The only complaint that I have is the blue light that does not have an off...My teenage daughter has allergies to our cats and we have put this in her room, and within 2-3 days she sleeps perfectly well with zero allergy symptoms. I have severe respiratory allergies.
