Perfect fit- Furnace Filter

Ordering online was easy and convenient. Filter fit perfectly since I was able to give specific measurements that would work for my AprilAir Furnace Filter. Was tired of throwing away money when buying disposible filters every month. These accordian style filters were quited costly. Wish I would have bought this fiter sooner. Was worried it would fit well. I measured several times and filter fit perfectly. Will reorder to have another one on hand. Glad shipping was free and made in the USA.

Works Great!

The filter is flexible enough and is a perfect fit. Glad you had custom sizes. I would recommend you guys to everyone. East to clean and reuse.


Unpacked it and slid it in, it was just that easy. The one the hvac people put in was an inch and a half short at the top and sometimes you just have to do it yourself. Carter Goods did me, right! Let them do you right too!

So far so good ask me again on April 1st when I clean it for the 1st time then I can let you know better?

Looks like it's working!

I bought two large custom filters for the house we just moved into. Having experience with ES filters but not thick ones, the customer service was helpful determining how often to clean. I've left one in for ~2 months now and the buildup is visible but not unmanageable. I cleaned the first filter and switched the second one in. My biggest complaint is that the tabs provided for ease of pulling the filters out don't really work on a filter that large. Overall, it fits, it works, and it seems to be washable, which is ultimately what I was looking for.
