Great reliable company for great filters!

The filters I ordered were great. The size was exactly as advertised, filter size and actual filter size. Other companies I have tried have not met this requirement. I have tried getting the 10x10x2 filters at other places and I am so happy I found a company that I can rely on getting what need and the correct item. The other companies fall short on their product being the actual size they advertise. The Merv 13 filters are great. I highly recommend Filter King for all your filter needs.

Love them

I have a hard time finding my furnace filters in a store. I found them online and I love it. Fast delivery, great product, and I absolutely love that they send a text when it's time to change the filter in the furnace. ( we forget )

Great custom filter service

I had been struggling to find reasonably priced filters for my discontinued model air purifier. But here I was able to get 6 for the price of one or two of the OEM ones. Custom built to my size, produced and shipped quickly.
