Customer service was beyond great. One package of my original shipment went astray. Discountfilters immediately shipped out a replacement, at no additional cost to me. The filters themselves are of sturdy construction. These filters, along with a box fan, are being used to make ‘homemade Covid filter boxes that we are using at my Temple. We’ve made 4 and if they work out for us, I will definitely be coming back to Discountfilters for more.

This product is great! I purchase this size for my elderly neighbor with breathing issues. I purchase this same product in a different size for my residence. I have a shedding breed of dog and a long-haired cat and the MERV 13 is perfect for me!

Had a defective one in the box it was made wrong on one side of the filter other than that quality is there just had a bad one out the group of them I would suggest better packaging of the filters they are exposed to bending or breaking due to shipping travel with no cushioning inside the box just bare filters inside a box with no protection incorporated inside or bubbles or something they need to work on that besides that the quality is there

Well, these are excellent filters at a good price. The service from Discount Filters has always been excellent and expedient. In the south, we have to change them more frequently because of the pollen here. I am a long time, satisfied customer and will continue to be so. Their discounts are very helpful for long-time customers. I have both standard and special size filters that are always perfectly fitted. Easy to order, and easy to go to the website to search for what you need.

It is so nice to save so much money and still get high quality air filters. I have asthmatic kids so I have to buy high end filters. I also have 4, count them, 4 filters in my home, 3 different sizes. Its was running 70$ every 3 months for filters. This is a much better, economical way!

My only comment is that the 20X20X1 filters measure at 19.5X19.5X1 which is too short to fit my A/C vent openings. The 20x20x1 filters bought from major manufacturers are 19.75X19.75 and they are a better fit for me.
Julie Anne Dick 5 days ago
I wish I could give more stars, but the filter is about 1/4 inch too small in both length and width, leaving a small gap open on two sides no matter how carefully it is placed.

You can't beat this. The best filter rating for removal of dust, bacteria, etc. More importantly, the best price you can find. Who said American products cost more? But these and you won't be disappointed.

I like these filters and when shipped from Discount Filters they arrive undamaged. My biggest concern is if I ever have an experience like I had with the 18x18's it will not be pretty. So I think I am done with Discount Filters.

I ordered air filters several times from discount filters, and Always been very happy. This time the shipping company crushed one of the boxes with six air filters. I emailed pictures, and got a replacement in about five days with no hassle. About the best customer service I've experienced with any of my purchases.
