I had to order a custom size filter to go with my furnace on my geothermal system. These are almost, not quite, twice the size of a normal furnace filter. On the website, I was able to enter the exact measurements and check the price against other dealers. The price and shipping I ended up with were good, and the delivery was in good time.

The filter for our furnace is effectively taking care of the impurities in our fur-filled home. We thank you for the quality of your product!

I have had great service from my Purolator Airfilters. Usually my orders are filled within a 3 week period and arrive at my doorstep. I have recommended these filters to a good friend and told them about my good experience ordering on line. They are also ordering these filters as I am.

We have a furnace that requires an odd sized filter hard to find locally, so we have been ordering them in the mail for years and have never had any poroblems

After much searching online, I finally found a site where I can order custom-sized heat pump filters. The filters are the exact size I needed, and made of the exact materials I wanted. Online ordering was easy and the filters were delivered quickly. I am 100% pleased with the product and the company.
