Pleased with my filter purchase.

Couldn't be happier with my purchase. Originally, I ordered 2 of the 16x25x4. Turned out I needed 16x25x5. Contacted Filter King and they had the replacement files sent out immediately. Victoria the Customer Service representative was amazing at helping me with the correct size. Thank you.

Great supplier

I was pleasantly surprised with your product. I thought I was taking a chance ordering from you, but it turned out great considering all the web sights that offer what I needed and the price to boot. Will definitely be back when I need to order more. The service, delivery time was just what I hoped for.

Great prices and excellent customer support

My shipment came in two boxes, and one of the boxes was damaged badly enough that one of the filters was completely unusable. I notified Filter King support and they quickly sent out a replacement. I was already happy with Filter King because they had the best price I could find, but even happier with their customer support. I highly recommend them.
