Bought two sets. One as shown above and another, 25x25x1.

Installed one filter of each. Both were as specified and fit the return openings. Filters have not been inservice long enough to rate efficiency (based on past orders, expect them to work fine).
I'm going to continue buying these, even though the price is a bit high

The big box boys are putting price pressure on Filterbuy with their in-house product . But since these filters are visibly catching a lot of debris while I replace them monthly, I'm not going to give the probably inferior big box product a try.
3rd time or so I have purchased filters from this company. The filters are not too restrictive do the job. I change monthly in cold months they may not be too dirty but heating systems need clean filters . Never neglect this , it's like not changing the oil on your car . a clogged filter will make your system work harder and may lead to more repairs down the road.
