The filters I have been using are 16x25x5. Will the 16x25x4 work in my system?

Probably not without some minor adjustment or filler in filter rack. Shouldn't be a big deal but I woudln't attempt it unless your are handy amount mechnaical equipment. Important thing is all the circulating air has to pass through the filter, not around it so filer has to be snug.

I expect they would fit since it is 1 inch smaller. But, I don't know if that is something you should do. I recommend calling a few different HVAC places to get their opinions.

Yes, those are the physical dimensions. Those dimensions are printed on the filters, but in smaller type than the nominal dimensions of 25" x 16 x 4"

The filters are made for what ever size you order. It is a good product. I am very happy with it.

Annie, have no idea about which is correct. Just know that these filters do fit. Wish I could be of more help, but am not a techie person !

I thought I answered this yesterday but will submit again. I purchased 1 pack of 4 filters, as you can see from my purchase history back in June. And they were listed as 20 x 25 x 4 but the 4" is not accurate, they will not fit my filter housing in my furnace.

I doubt it will fit in a 20X25X1 slot as it is a 4 inch thick filter. My large heat pump uses the 20X24X4 and they are changed every 6 months by the company doing my service contract. It has a huge amount more filter area than the 20X25X1 so it does not need to be changed as often, but would need to fit air tight in the space for your filter.

This filter is 5.7/8 inches long by 3.7/8 to be exact. Otherwise 4x6. Hope this helps.

It would be best to take your filters into a home store and get what you need there. We had to return these, and I am not sure of the size... But they were really small. When I typed in my filter model number these came up first, so I was sure they would work (and was STOKED about the price!!). Then, like I said, had to return them. Sorry I couldn't answer your question specifically, but hopefully it helps.

I buy the 20 x 25 x 1 and the size is actual. Fits perfectly. Be sure to put the arrow on the side of the filter pointing into the opening.

These filters are NOT 25x20x1. They are 19.5x24.5.x1 and they barely fit in my HVAC system. I am most likely going to return them because they leave a gap. I think this is terribly misleading. As we all know...1/2" makes a lot of difference.

This filter measures 3/4 x 1-3/4. I suggest that you measure the one in you machine and see if they match

The one I bought was suppose to be 20x20 and that's what it was. Seems like they measure what they claim to be. I know some people claim some filters are a quarter of inch off, but these measure what they claim.

I purchased the 16x25x4 and it is 4 inches almost exactly. Fits my filter housing just right. I can't speak for the other size which sounds like it is 4.5 inches depth. Hope that helps.

The filters I bought is model HCM-750 series and they are rectangular, around 11.5 X 16 cm

Standard size filters work. Home Depot carries them for sure. That is where I buy mine. Good luck.

I'm not sure so I would contact the manufacturers of the system and the filters. If it does not I am sure they would have an experts answer to your problem.
