Great price on filters when I bought in bulk. I will use them over the course of 15-18 months. So far, I've been very happy with the purchase.

We get a very good price from Filter Buy and we very glad that the filters are individually wrapped since this is a year’s worth of filters for us. Thank you!

Two heat pump air filters every six months

Always on time and correct sized filters. One is custom and the other standard.
I attribute the long life of our smaller heat pump to frequent changes of MERV 13 air filters!!
