Aaria + humidifier gets 5 solid stars. I’ve tried thus product for a couple of weeks and I really liked. The air in my house gets dry in the cold winter months and thus works wonders. I used the sanitizing function and it works perfectly. It’s very quiet and I think that’s key to mention. The directions are very clear and easy to follow. There wasn’t really anything to put together, which was great. I only needed them upon initial use. Definitely a must have in every home.
