tested the blue camco filter with a TDS meter

I use a filter and housing from one of the box stores in the area I'm staying at. This system uses the same filter used in a home system, change it out as directed and the water quality is good. I use a pitcher system for drinking water.
I use one of the Camco filters to fill my water tank when traveling.

I use the Camco filter, not to make campground spigot water drinkable but to remove small debri particles from what goes into my camper. I'm more concerned about a rust flake from plumbing from a old campground plumbing system that may have been built 50+ years ago getting into a check valve or my water pump and causing a problem.

I haul my own drinking water for week long trips and use a pitcher filter for longer ones.

Sorry not trying to over complicate. My first trailer being over protective about silly stuff like water in the tanks.

Use the Blue in-line filters all the time......have done so for many years
Use fresh water tank for everything...cooking, coffee/tea, washing, showering, teeth brushing and DRINKING.
Fresh water tank is just a big ole water bottle
Water that goes in it is from city water supply..just like at home

S&B water is not filtered to remove TDS etc
RV is just like S&B.....

Folks sure do like to make RVng complicated :H

So get an RO. Plenty of people have them.

My Village R/O is for salt water and it yields a nominal 2ppm.

But

It consumes a lot of power and passes a lot of water

The filters are expensive

And chlorine is pure death to genuine R/O filters.

Wow interesting. Somewhat familiar how charcoal removes impurities. Guess those are not solids. Excited to learn more.

The Camco filter is designed to make the water taste better, not lower TDS. It's a far cry from an RO filter and the two can't be compared.

You can find good cartridges that do more than just make the water taste better - they're rated at 0.5 microns and fit a standard cartridge canister. They're much too restrictive to filter all the water going into your RV - your pressure at the faucet will be awful.

Here's an example of a 0.5 micron filter cartridge:

If all you want is to make the water taste better and remove any smell, you can do that with any charcoal filter cartridge which will allow full flow to your faucets.

If you want completely safe water, you'll need to buy it by the gallon. Make sure it's purified by a RO process.

I put one of the 0.5 filters in the line to the special drinking water spigot on our sink but we also buy water by the gallon.

Yeah i do want a filter. Looked around home depot. Not going the drink the water, i just like the idea of somewhat clean water being in the tanks.

Anyone have a "not gonna drink it" quality of filter they would recommend for my peace of mind?

So it does nothing. Got it. If you need a filter there are better systems out there. They just cost more.
