I have been using these filters for a while & another filter company were sending promos for their filters. So I did some more research into Filterbuy as a company. There are 2 reasons I went with Filterbuy, MADE IN USA & they produce filters in Pittsburgh PA. I live in Pittsburgh so you have to support local!!!

We go from heat to nothing to air conditioning in a matter of days here, so I won't go without knowing the air is being filtered. FilterBuy is my favorite!

I am a repeat customer. The filters are great. i have pets, and the merv 13 seems to do a good job of picking up all the allergens.
