Product is great and service is great! However, you send too many emails for sales. After I place an order, I keep receiving more advertising emails. When I purchase from your company, I’m satisfying my need for the next year. I love your product and company, but please find a way to back off on the advertising, especially after an order has been placed and received. Thank you.

Discount Filters has great customer service. I accidentally ordered these filters when I really needed other filters that fit my air purifier. After contacting Discount Filters they responded very helpfully.

Love the product. We've been using this filter for a couple of years now. The quality is great. We buy a box every time we run out so we get some great deals! I like buying the 2" over the 1" thickness. I think it's a better product and works well with my unit.

As with everything else that is going on, I notice the quality in everything is going down. If the product doesn’t last as long so they can sell more. Nothing last anymore.

I change filters when the seasons change. I like having a surplus on hand of the right filters to make it easier for me to change them.

Best price and best filter for the money. Second time I have ordered from Discount Filters and will order again. Also, other vendors package their filters by the dozen. With DF, I was able to order smaller quantities, 6 to a package.
