After 1 week of using the new filter I could tell the air quality in our home was better. I have one cat (Leo) that sheds a lot despite routine brushing. I havent been sneezing nearly as much since using the filters. Maybe Leo will soon be getting a new friend.
Filters were fine other than being out of stock of merv 11s. But the constant emails and multiple attempts too snare an auto subscription is a huge hassle.
