Very happy with this replacement filter. I was hesitant to purchase it initially due to other reviews I had read stating that it didn’t fit the unit properly. I have the Winix 9500. It fit perfectly. The black tabs that stick out simply make it easier to remove the filter. My unit works like new again. – Buyer
