Great Filter-Reliable Replacement Program

Perfect fit for hard to find size (20x23). Seems to perform as claimed by seller, as filter is completely covered with dirt and dust when it is changed at the recommended time intervals.I set filter change reminders on my IPhone to help me remember when to replace dirty filters. I signed up for auto ship so I wont run out of filters and to receive a better lower price.

Could not have been easier. Ordered filters, and they showed up pretty quickly to my house. Good quality, well packaged. Will be using again in the future.

Just installed my first filter on October 1st. Filters purchased and inspected seem of very good quality. The specs are what I requested and will work for the meanwhile. However, I will need to tweak or modify filter specs for next purchase. My specs fall between 20x34x1 and 20x36x1. The 20x36x1 filters from previous company was always a tight and crunched fit to install. Your filters, 20x34x1 was a perfect fit without the sides being crunched into slots or the length being too much and crunched.
