I know this sounds crazy but I am wanting to experiment with a filter and housing to use attached to my spigot outside my pole barn garage. The purpose would be to wash my cars so there are no water spots and no need to dry them. I have three vehicles and it takes alot of time to wash them. Also, drying over time can leave spider web scratches if you are not extremely careful.

Is there a filter or housing you recommend? Is it possible to mount a filter housing outside even in freezing weather?

The Pro Detailing guys that wash cars on new car lots use a double
deionizer system, the two tall bottles on their truck or trailer. One
resin bed attracts positive ions, the other negative, and between the
two it gets pretty much everything out of the water.

You want to run a fine particulate filter before the deionizers, to
keep from loading them up.

Usually get those deionizer bottles as rentals on an exchange basis
from the local Water Softener people. You can buy your own and renew
the resin beds yourself but it's a huge process. Let them deal with
it in bulk.

Since they are fiberglass-wrapped pressure vessels with water inside,
they have to be kept above freezing inside the garage, or you'll need
to rig up heat wraps for the tanks if they are stored outside in
freezing conditions. And pray the power for the heat wraps doesn't go
off and they get wrecked anyway.

No rule saying you can't rig them up semi-permanent inside the Pole
Barn in a nice little heated closet, then put a frost-proof spigot on
the outside. You already have water in the barn, so you know what has
to be done in your area to keep things from freezing.
