    Nice and quiet, cleans the air quickly and is getting me through intense Fla allergy season in good shape! The design is attractive, and the machine is easy to keep clean. I bought reusable washable covers and put myself on the autoship filter supply list! Such a good design and easy to use! I am happy with the purchase- this is my second 311i one is in my bedroom at the other end of the home- thanks Blue Air🫶

    LOVE the Blue Pure 311i Max!

    The Blue Pure 311i Max is our third, and largest Blueair air purifier in our home. We have two small dogs (less than 20lbs), that shed. We bought this 311i Max to help with reducing allergens in the living area of the house, as it seems daily vacuums/dusting is not enough! In the short time we’ve had the 311i Max, the air quality is noticeably better. How do I know? I am not sneezing every morning when I sit and drink my coffee! And, I love the outer pre-filter sleeve…I can change the color to match the room decor and seasonal changes!
