I have ordered from filtersfast for years and I paid more for 1 filter than I ever have before. I used to get 3 in a box for the same price I paid for one! What has changed?

This filter is used in my heating system and I change it twice a year. It does a great job.

This was a replacement for the original filter in a new heating system. It was the exact brand as the first and fits well.
