Does not fit properly
on August 25, 2023
Posted by: Eugene G.
The size in the title is different from the actual size of the filter. It rocks back and forth in the filter housing. When you ak them about it, they point to the different dimensions in the description. Why would any human assume a different description of size from the title. Returns cost you time and money. I will throw them away and eat the cost.

Not what I expected

The 36 inch wide filter is a 24 inch and 12 inch wide filter taped together. Doesnt match the picture or description. In addition, you cant handle the filter too much as the cardboard body of the filter will start to peel away from the filter material.

Size matters

Very disappointing to find these filters are not true to size. I never knew that furnace filters came in nominal sizes and actually substantially different.

My filter size was getting impossible to find anywhere. I found that I could order them here so I will be subscribing to a yearly renewal of my order. Havent needed to use yet so hopefully will fit well.

Was amazed that these filters were less expensive than on other sites. Haven't used 1 yet so will compare to previous purchases at a later date.
