Customer Reviews
Easy to order, good filter
I needed a weird size for my furnace, and finding it was super easy here. The Merv 11 filter I got came pretty quick, took about 5 days to reach Denver. It fit perfectly, which is always a relief with custom stuff. No issues at all, happy with it.
Reliable for custom sizes
This is my third time ordering from Custom Filters Direct, and they've been consistent every time. I always get the custom size furnace filters because my unit needs a specific fit. This last order for the pleated air filters was just like the others; good quality and they arrived within the week. I keep coming back because their filters always fit right and they get here without a hitch, unlike some other places I tried before.

Hey, thinking of ordering some custom filters because my local stores just don't have my weird size. How long do these usually take to ship out? Don't want to be without a filter for too long.
