I know this sounds crazy but I am wanting to experiment with a filter and h ousing to use attached to my spigot outside my pole barn garage. The purpos e would be to wash my cars so there are no water spots and no need to dry t hem. I have three vehicles and it takes alot of time to wash them. Also, dr ying over time can leave spider web scratches if you are not extremely care ful.
Is there a filter or housing you recommend? Is it possible to mount a filte r housing outside even in freezing weather?
