"Standard" faucet filter use in an RV?

I'm a full timer. I've been using distilled bottled water. I would prefer to use a Pur faucet filter, like the kind used in houses and apartments, where I don't have to go through a lot of trouble. I can just screw it to the faucet, flip a lever when I want filtered water and have easy access to change the filters.

My concern is that it will raise the water pressure too high in my systems and cause a leak.

My rig is rated for 55psi on the plumbing. I use a manually adjustable flow regulator on the hydrant to keep my static pressure right at 55psi; which gives me a flow pressure right at 50psi. And I actually like the pressure where it currently is.

When I research online I see all kinds of comparatively expensive stuff that sits outside and filters all water. I only need it for cooking and drinking. And yes, I do have an exterior sediment filter. But I won't drink unfiltered city water.

When researching online I also see a lot of systems that mount under the kitchen sink and require me to change out the faucet. Frankly, I do not want to deal with all of that. I have mobility issues due to a neck injury and I don't want to have to crawl under a sink every few months to change a filter.

As far as I can tell a Pur/Britta on tap filter is the easiest and cheapest solution to achieve the filtration levels I desire.

The question is: Will it blow up my plumbing?

    Only a pump can increase pressure, the filter has no pump.

    I think the OP is talking about possible leaks caused by the filter creating a restriction and raising pressure.

    If the water system is in good condition it won't cause any leaks. When you run water now and shut it off the pump runs for a few seconds. That's more pressure than will be generated by a restriction (filter) in the water line.
    No, it won't blow up.
  • I use a 1 micron external filter attached to my hose line outside my 5er. This keeps the dirt out of the system. Inside I use the "Zero" water system for drinking.
