Why are they 3 sizes? width, height and what? Our filters are 4x6. What size do we order?

There are 3 sizes for filters for different size filter systems. I bought the large, it fits my Aqueon Quiet flow 50. I had a smaller tank and with that a smaller filter system and that system took the medium cartridges. You can search on your filter system for it's size or model number then search online for the right size filter. Good Luck

There are different size filters for different size tanks. So that's why there is different size cartridges. Sounds like u need the large.

You select the size you need from the pull down list at the top of the page under the word "Size:" and above "Unit Count". The size listed, for example 20x25x1, is the actual dimensions in inches of the filter you'll receive.

I got 6, but be careful on the "actual filter dimensions". The dimensions on the box are different than what is inside. I'm still using them even though the filters are about 2 inches narrower than what I was expecting.

These fit the 48 sq.ft filter. I believe they come in the size that fits the 36 sq.ft filter also.

The product dimensions are 6.5 x 6.8 inches, with each filter being less than 1" thick.

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

I actually bought the 16x25x4 filters. They measure a little more (.5 inch maybe) than the stated size. Hope that works.

The 2.8 x 2.8 x 2.8 measurement is the size of the box the two filters come in. Karen L. Forbes posted measurements are fairly accurate to actual filter size.

the filters seem to be the same size. 12.7 x 1.2 x 16.4 according to the description

The filter measures 6" x 13 ". Just removed the old one that you have and check if they have the same measurement.

This same thing happened to me. Regarding the previous commenters suggesting that it was just a tight fit or that I wasn't lining up the rails correctly was not the case. The filter I received was literally 3-4 inches too wide and was also only 4 inches tall. I think I just received the wrong size.

The filter is about 3 inches wide from the top and a little under 4 inches wide in the middle. I hope that helps.

Yes, we can make a 20x25x4 filter. Please do not stack as this will cause too much resistance. Do you have a brand and model # on your current filter? Thanks Clean Air Solutions LLC

Did ya'll even buy this filter?? The dimensions mentioned above are the size of the filter FOLDED UP IN THE BAGGIE FOR SHIPPING. When you actually BUY the filter and spread it out, you will discover the pre-filter is 16 inches x 48 inches.

I measured. Two inches high by four inches diameter. Can widen out to 6 inches or scrunch up to two since they are pleated. Hope this works for you. They are really good sturdy filters.

It fits my whole house filter. On dimensions, I don't have those right at the moment and the filter is installed at a location where I don't go too much. I purchased as a property management item and don't have them readily available, sorry. They did fit for what I have.

Not sure about all of them. I have the 5 filter system. I just installed them. Direct fit. I'll order them again. Hope that helped.
