Great shipping .

Very happy with the service

Quick and easy

I have ordered filters from this company for more than two years. Pleased with service and products ordered.

The filters arrived very quickly and everybody was really nice as far as the service went I would recommend them to anybody

My product was in stock when I ordered, it shipped out quickly, Discount Filter Store kept me in the during the shipping process and the filters arrived undamaged!!! I'll be ordering again from Discount Filter Store when I'm ready for new filters for my air conditioning!!!

Product far exceeded expectations and we will be purchasing annually to maintain a rust free driveway and rust free landscaping.

Great customer service, quality and price! Definitely recommend

This is the only place I'll buy filters from, great prices, great customer service and quality products. You won't be disappointed.

Very great service
