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.

The filters arrived with one of them slightly crushed on one end. I was able to slide it into my filter space. It's there now. I'll know more at the end of the month when I inspect it. No reason to think it won't do the job!
