In the time of COVID, I could not find any filters in my local store. This company responded quickly and I have been a happy customer ever since. They send a reminder, or you can get on a prearranged scheduled of shipping. American made and I am a very loyal customer.

I've found that these filters are just as effective as any other filters I've bought, but they are a bit more affordable. The shipping is quick and the packaging is substantial. I have never received a crushed box.

I mistakenly ordered the wrong size filter. Discount Filters sent me a replacement filter the next day. They also did not require the wrong filter be returned. They suggested I donate it a non-profit organization. Good job!

I was previously getting these filters from another source but those filters had to be unfolded and reassembled. These come fully assembled and are easier to install.

Price keeps going up, but filters r top quality....as good as our A/C contractor provides...maybe u could keep ur coupons active for a little longer...they always come in my inbox when I dont need to reorder yet...
