Timely and helpful

I ordered four filters. I got what I ordered on time, and they fit my furnace nicely. I labeled them with dates so I know when to change them. Good to know I'm all set for the next year.

This filter fits the area

This filter fits the area perfect easily installed and removed. I write installed date and change it every three months. Catches a lot of dust. House air feels cleaner.
