I had delivery damage twice. Customer Service came through and had replacements delivered promptly in both instances with no hassles. I like the Merv 8 filters. They cost less than Merv 5 at the big box stores. I highly recommend Discount Filters because of their quality products and great customer service. Buy extras to have on hand.

This filter size10x20x1 is a standard measurement. The quality of the filter and value for a package of 12 was very good. I would definitely purchase again. I have also referred this company and their online website to several friends and family members to consider.

Lowe’s was out of affordable filters. Only expensive ones left. I found this site and am so glad I did! These are so reasonably priced, perfect fit and great quality. Got here super fast. I advise to stock up since we are seeing the effects of the supply chain issues!

We have to change our filters monthly since we live in an older home. These are definitely reasonably priced so it doesn't break the bank!

Good filters for the money. Been using these for several years now and haven’t had any problems. After ordering these filters they were on my front porch in only a few days. Extremely happy.

Convenient. It is hard for me to find this size filter in my area. It is convenient for me to get them from Discount Filters. I am disabled and unable to do much shopping, physically, therefore being able to get them online is a God-send.

Took longer than expected due to back order. This was not a problem since we had recently replaced the old filter. Have not used the filter but based on comparison to previous brand from Lowe’s, these filters look to be much better quality. Also, arrived in a box inside a box. So I appreciate the care taken to make sure they arrived safely.
