Water filter.

Does my 2021 Int 25FBT have a water filter to replace? If it does, I can't find it?

Do you mean:
1) -- a filter between the fresh water tank and the pump;
2) -- a filter for pure drinking water at/under the galley sink?

What does your owner's manual say, and if 2) is there a separate mfg. brochure for the filter in your Airstream briefcase?

Have you looked at your pump for a pre-filter on the line coming from the water tank? You need to know the pump's location for winterizing anyway BTW.

How about under the galley sink . . . any filter housing there?

It would be unusual for there to be a built in filter ( as opposed to a strainer ) on the water input to the trailer. Most folks who go that way rig something in series with the hose that feeds in the water.

Some (but not all) AS trailers have a filter under the kitchen sink. If so it's pretty obvious sitting there when you look for it. If you have one, there also should be a "straight through" pile that replaces it rumbling around somewhere.

Since this is a 2021 (and this time of year actually could be a 2022 if it's new) there isn't a lot to go on other than what's been on older trailers.
