    Big Difference

    My house is roughly 40 years old and has smelled musty for years. I now have Blue Pure air filters in 3 parts of my house. The two 511I Max units are in two bedrooms. The air in those rooms smells and feels cleaner. I'm glad I purchased them.

    Blueair 211ii Max Air Purifier

    This air purifier as worked very well from the start. I've been using it for several weeks. It has already greatly reduced the amount of dust on the furniture! I run it on the Auto setting and it promptly responds to any kitchen-generated odors from cooking. The unit can be controlled from the app via WiFi which I find useful; with additional control of it compared to using just the buttons of the top of the purifier. However, you can use the air purifier just fine without using the app.

    It is very quiet and does not affect my ability to satisfactorily hear the TV. The overall design is clean, modern and unobtrusive. It is a quality device and I highly recommend it.
