Excellent Service

Amazing customer service. I had ordered air filters in bulk. New furnace was installed and needed a different size. CS replaced the entire batch with the new size filters and sent a return label for the remaining old ones. One vendor I would pay more for their service.

5 Star Experience!

I highly recommend Filter King! The filters are high quality, the prices are better than I have found anywhere else and the customer service is one of the best I've ever experienced. I rarely give reviews, but my experience with Filter King was so positive that I wanted to share this with others.

4 Pk of Filters Damaged

Ordered my correct sized filters for our church and they arrived very damaged and unusable from the carrier FedEx. Relayed the information immediately with proof pics of box and had a response with 20mins from customer service with their apologies and a new set with tracking was attached at no cost. With a 5% discount for my next purchase. New set came perfect and fast. Can not say enough about the customer service by them on a issue which was not their fault but the carriers. Thank you
