Water Filter

Anyone have any thoughts on how long water can sit in an under-sink filter between camping trips without becoming a health problem?
  • -Been There Done That Dept-

    Remove filter
    Add three drops of water purifier IODINE
    Assemble

    Run an few quarts of fresh tank water through the filter before re-using. Iodine kills moss, bacteria, amoeba, protozoa, and keeps working for years. Follow directions on label for dosage. If you won't hurt you if you purify water in a drinking glass it won't hurt you in a filter, especially one that gets a flushing.

    Quicksilver, is stored with 1.15 pints of purified iodine in the filled water tank, throughout the system including pump lines and faucets. But when I go to use it, it sure gets one heck of a flushing. Iodine is far and away easier on pumps and seals than chlorine bleach, plus it is far more potent and long lasting. I scribbled a reminder YODO/IODINE on post-it-notes for the sink and shower, especially to remind the kids.
  • Read an article in an RV magazine about this and they recommended taking it out between trips putting it in a sealed bag and keeping it in the refrigerator. No drying it out just leave the water in it and put it in the frig.

    Unless you keep your AC running 24/7 between trips, it can get pretty warm inside. Many filters list a max. temp. which can easily be exceeded in the summer - check the specs. It's a pain, but the best thing would be to remove it and store it in the fridge. Just don't put it in the freezer. As mentioned, heat + moisture = bacterial growth. Some filters have KDF or silver in them, but this only kills bacteria on the surface of the filter cartridge, not inside it.

    Good point - I'm beginning to think a water filter should be dried out if the camper isn't going to be used for say a month.

    From what I read drying out isn't recommended because charcoal will loosen and come out for for awhile when it is reused. I'll just let it run a couple minutes until it clears. Better that than getting swamp fever!

  • If I am storing my rig for any length of time the filter is removed. Since mine is a cartridge I can dry and reuse or if dirty I replace it.

    And on the label of filters it states not to let filter get completely dried out. So x2 on putting a new one in at the start of the season.

    We always replaced our water filter on our 5th wheel at the beginning of the camping season each year...
