Dimensions

These replacement filters fit my furnace. The listed dimensions are not exactly correct but the filters are made to the dimensions of the filter slot. Standard 20x25x5 filters do not fit.The Generalaire filters work perfectly but I don't like the fact that they are the only ones.

Stifles the Air

Provides the feel of cleaner air flow, however it makes the A/C feel like it is pulling harder because of the thickness of the filter.

Great filters

I bought MERV 11. The higher MERV 12 filters are too tight limiting air flow and ultimately causing the AC to over work. This is similar to how the AC FILTER in your motor car works. You may be better off finding a filter similar to a K&N filter which is a super air flow filter but uses oil to filter rather than just paper
