Ive been buying Filter Buy filters for 3 years, since we moved here, because those were the filters in use when we got here. Ive reordered the MERV 8 but this time (2 weeks ago) decided to upgrade to MERV 11. So far so good. The filters get dirty after 3 or 4 months so they are working. And our HVAC system seems to be happy. Also the price is very good. This latest order is the first where I did comparison shopping and I chose to reorder from Filter Buy.
Excellent product. I just started ordering first my neighbor as well. Knowing you are getting a great product is wonderful. I know it will be the right size and will have excellent protection compared to purchasing the filter from a store gives me total confidence that I am taking care of my AC unit. Thank you! (o:
