under sink single filter unit

[marsc]

I am looking for a filter for an under-sink single filter unit that was manufactured by Beam. The part number of was W175102.

It is 12 inches long by 2 ½ in diameter. The inside diameter at the gaskets is 1 inch.

That is a very unique size. Most filters are about 10 inches by 2.5 inches. Here are the more standard systems, if you would like to get a new housing that is more standard.
