Trying the brand of filter for the first time. Give me three months and I will tell you it I like this filter. The only thing I notice is the total filter area is less than the filter I replaced. I assume that is why it cost less.
they seem to do a good job my spouse and i seem to be sick less since we have started using the merv13 possible problem is that 2 AC guys have said you shouldn't use anything over merv 8, because it makes the AC unit work too hard.i don't care, because i feel like the air quality is worth it...........
So very happy with Filter Buys monthly program and quality filters. I purchase the medical quality filters that trap an amazing amount of particles that we would otherwise be breathing. Great service!
