if you mean will it fit a standard filter housing ... yes

No does not fit the canister that i use for a 10" carbon filter and a 10" 1 micron filter. The beer filter cartrige is too long such that the caniter will not tighten down. You may have better luck

It fit my housing and I use the standard size like you get at Home Depot. I recommend it.

In what respect I will guess that it is usable in filtering wine or beer and it fits any filter system with a 10 inch double open end housing that is similar to a water filter. It would be a good idea to run anything not optically clear through a depfh filter of 1 micron first depending on how much wine you have to filter. I like this porosity rather than a sterile filter as it does not destroy the colloidal structure of a wine like a sterile filter might. Also it does not seem to have blow by or through like a poly or fiberglass depth cartridge. If pressure builds to say 25 or 35 psi either reverse flow and clean or remove and blow it back through with water by mouth or water hose pressuring it from the inside to clean it. They will not sterile filter a wine as all bacteria and some yeast are smaller than 1 micron. I don't care about that and want good clarity without stripping flavor or the structure and mouthfeel of the wine.

Yes. It’s made for a ten inch filter system. I’ve used it several times and it works well.

I doubt it is universal. Better measure

Not sure guess is until it no longer filters.I love mine and very easy to clean

Five times so far. I guess I'll find out. I don't think it works as well as the disposable ones.

You need sodium percarbonate (Oxyclean) to actually wash these filters. I rinse mine first then soak it in a pitcher just larger enough using warm water and about 1-2 tbsp of sodium percarbonate. Do NOT try and take this apart the only things you can remove are the rubber end seals and those don't get you access to anything. After washing I'll leave it in a window to dry in the sun flip it a few times to make sure as much of the water evaporates as possible. Store in a plastic sleeve or Ziploc and always sterilize it again before every re-use. I've used my filter about 5 times now for mead and it's still looking pretty fresh with this method

For me I first try to get everything off of it. I normally taking the housing lid off and blast hot water down the middle (while in the lower part of the housing) to force things off the outer side. I'll do this several times until the water isn't murky. Then I give it a hot PBW bath for 24 hours in the housing. When done I repeat the blasting hot water down the middle while it sits in the bottom part of the housing. I should see pure water coming from it before I decide I'm done. I hope this helps!
