Perform as well as more expensive versions. I buy a 6-pack each time since we change them out every quarter.

The product is ok, however, my discount coupon was not accepted.

Always good and dependable,

Well built, consistent sizing and webbing. I am very pleased quality for the price and convenience of the bulk shipment.

Very good product the Air filter that you buy at the home improvement stores my system tears them up in a couple of days because the filter frame work isn't strong enough but i don't have that problem with FilterFast filters they r made strong and i thank you for that. Keep the good Job UP!!! Thank You

good stuff cheao

I am very pleased with the filters I get from your company for my heating& air conditioner! Very fast service & I have hard to find filter size but you always have what I need !

Great filter. I had a hard to find size and through this service not only I found the perfect size but also a great value for the money.

Excellent filters saves money.

Last and filter as they should worth the money

Was able to get my hard to find size!

Good product.

I ordered the 2 pack through Amazon, to try them out, and am very impressed, compaired to the ones that are supplied by the apt. complex (fiberglass)these are great and fit perfectly, good product. Will order more of these in the future.

Excellent to replace the one month replacement type on houses with pets.

They ship in a timely manner .

Good price, delivery on time.

Reasonable and efficient.

Took a chance and was not disappointed. No name brand filter seems just as good as 3m filtrete.

Great products. Only issue is shipping box was a little light and corners crushed. Therefor a filter or two were crushed but salvageable.

I haven' t used these yet, however I' ve purchased before and they are fine. Do what they are supposed to do, and well priced.

These filters are perfect for my usage. Seem to work well and I have no negative comments. I will buy them again

When I discovered that our new heat pump unit required an unusual size filter I wanted to ensure it was high quality, and available quickly. I was not disappointed in either case! Thank you.

Their ability to fabricate custom sizes of their filters is what I needed and got. Great job. Thank you.

My filters arrived quickly and in good condition. No problems at all. A speedy delivery. Thank you

I ordered, it came , I installed, lifer is good.

Great Filters at great prices.

They fit perfectly and work great. It is so much easier to order a case online and have them delivered. The price is really good too.

These work great for low $

Merv 8 filters are what was recommended to use by the installer of our system. Hard to find them locally in the size I use (20x25x1). Conveniently shipped direct to my door.

Easy to buy odd-sized filters.

A great value purchase very happy.

These folks have continued to provide the filters I need

Good price! It work fine.

Great product and very cost effective.

Good product at a fair price arrived at my home fast. This was not my first order and won' t be the last.

Reordered these and these are excellent filters at a very good price. Thanks

I have trouble finding the right side of filters for my furnace locally, but these are perfect and ship fast.

Your Johnny on the spot to send them and the service is great but would appreciate a call before a new order is sent. Our A/C is new and very efficient.

Wish I could afford a higher Merv rating, but having multiple units makes it a very expensive item. I like the convenience of buying multiple filters in the same size, just wish the higher Merv rated filters weren' t so expensive.

I change on the 1st of every month, no problems, works great.
