I have been sneezing like crazy every morning, but since installing your filter I am not sneezing nearly as much! My roommate even commented on it. The fit is really nice, and mine isn't one to easy to find! The best part of all, when ready to change this filter, I always have one on hand with your subscription service. Saves me the hassle of going out and buying a filter which I much appreciate, especially with the Covid19
they do the job and are much easier to install timewise. however, a bit more expensive and seem to need to replace sooner than fan type previously used. subjective?????possibly
