We’ve had the regular blue pure 411 for a year and loved it so when I saw this auto come out, I had to try it. We just keep it running all day in the bedroom and it never bothered us.
I love the super simple design and affordable price. Although it’s small it works much better than our expensive Sharp air purifier imo. The air in the room is totally different if you have this air purifier running.
I think we will buy another one next year!
