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 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.

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.

EXACTLY! Spot on.

Cool, thank you very much. That's what I was hoping to hear. But I wanted to check in with some more experienced folks before I went and blew something up.

A faucet with a filter is not going to cause more pressure than a faucet that isn't flowing any water at all, i.e., shut off.

OK, when you put it that way it's pretty obvious.

But I didn't think about it that way.

Maybe I should have had a V8?

It depends on what you're trying to filter out? If it's total dissolved solids (TDS), then you might be surprised to find out that many water filters apparently do little in this regard? We did some simple testing of the most popular filter used in our office, Brita pitcher water filters, and discovered they typically only achieved a 5% reduction in TDS using our tap water. Comparing Deer Park bottled spring water which represented an 85% TDS reduction from our tap. Though the only readily available filter that reduced TDS to 0-1% was Zero Water pitcher filters. It was by far the most effective water filter, outside of using a reverse osmosis system.

Besides using a TDS meter, we tested with a Precipitator, and Zero Water filters produced clear liquid. Others resulted in various degrees of brown, akin to coffee color in nature. Needless to say, we all switched to Zero filters.

We use a faucet mounted Pur filter as our final filter for reducing any remaining chlorine taste, lead, and mercury in our drinking water. Our primary filter is a whole house unit that filters all of the water coming into the RV for sediment and assorted nasties such as lead and mercury, as well as reducing the chlorine taste.
