That said, I purchased this air purifier for my motor home. My daughter and I have pretty severe seasonal allergies. We just got back from our 1st trip out and I feel that this purifier worked beautifully! I put in the bedroom because our allergies seem worse at night. I will say that when running on auto and it’s running at full speed it is a bit loud however it’s white noise while sleeping so it drowns it other noise that may be disrupted during sleep. It was super easy to set up( just plugin). Super simple to understand. I really feel better knowing I have this and will use it on every trip. I also feel that in the future if I should have an issue the company would be more than happy to fix any issues.”
