The BLUEAIR Blue Pure 311i Max Genuine Replacement Filter was a perfect fit and easy removal / install of this new one. The room continues to be clean and fresh smelling as it was with the original. Will continue to purchase these filters in the future.

This air purifier works well. It takes cooking odor out of the room and the level of dust seems to be noticeably less. I am not enamored with the cloth outside but a minor thing. Over all works well.
