How to "Double-Filter" RV Drinking Water

On our LongLongHoneymoon.com website, people sometimes ask, “Do you drink the water in your RV?”

Our reply? “Yes, and it’s delicious.”

We “double-filter” our drinking water, and it’s easy peasy. Here’s how we do it.

With regard to water sources, often we are reliant on unfamiliar public taps. So we use two products that work together to filter our drinking water. That’s why our water is double-filtered.

The first is the Camco TastePure water filter. This is simply a large water filter that easily attaches to the hose between the “city water” supply and the RV. It’s a big boy and promises to last the entire camping season. We typically use a new one at the beginning of summer. It filters all water before it ever enters our RV. (And by the way, you can save a lot of money on these filters if you buy a two-pack.)

The Camco RV water filter does a fine job to help produce great tasting drinking water. (Click the pic for more info.)

If you read the Camco fine print, the company promises a “100 micron fiber filter” that “greatly reduces bad taste, odors, chlorine and sediment in drinking water.” While I haven’t bothered to measure the microns, I know this filter works.

I’ll never forget the time we attached our filter to the well water supply at an old rural well in Texas. We didn’t realize that the well water was full of nasty sediment. When we turned on the well water, our Camco filter quickly clogged with dirt and mud. We ruined our filter on that day, but I was impressed that it caught so much sediment. It died for a good cause.

All city water is filtered before it enters our RV. (Click the pic for more info.)

Camco also promises that its product is a high-flow carbon filter “with KDF” to help prevent bacteria growth. Wait – what the heck is KDF? Is this kind of like Certs and Retsyn?

KDF stands for “Kinetic Degradation Fluxion.” Wait, you didn’t know that? Basically KDF is a metal alloy of both copper and zinc that is used in water filters to make them more effective. Water filtration media is used in a flaked or granulated particulate form and usually appears to be gold or brass in color. In other words, this filter has good stuff inside that works. Okay, now you can go back to forgetting what “KDF” means. Whew.

The second product we use with our drinking water is a Brita Bella water pitcher. The Bella is a small water pitcher that just barely fits inside our little Airstream RV refrigerator. (If you have a fullsize refrigerator, you could probably use a larger pitcher.) The pitcher has a standard Brita filter built into it. A side bonus is that this pitcher allows me to walk around our campsite shouting “Brita Bella!” in an exaggerated Italian accent (be sure to wave your hands & arms for best effect).

Yes kids, it's the "Brita Bella!" (said in exaggerated Italian accent). Water from our kitchen tap gets filtered a second time when poured into this pitcher. (Click the pic for more info.)

We put water from our kitchen faucet (water that was already filtered by the Camco before entering our RV holding tank) into the “Brita Bella!” pitcher. So the Brita pitcher filters our drinking water a second time.

Brita says its filters are specially engineered with “an Ion Exchange Resin” to grab hold of impurities found in tap water like lead, copper, mercury, cadmium, and zinc. Wait – what the heck is an Ion Exchange Resin? I could tell you in great detail, but I’m afraid it might put you to sleep. It’s kind of like KDF – good stuff inside that works.

With these two filtration systems working together, our drinking water tastes fantastic. It tastes fresh, clean, and free of impurities.

Of course, not everyone may want to take the step of double-filtering their RV drinking water. Some may want to simply choose one of these filters and leave it at that.

Since we are drinking daily straight from our RV tanks, we like to go the double filtration route. It costs a little more, but these water filters actually last an entire camping season. Of course it’s much cheaper and better for the environment than drinking bottled water. And the resulting drinking water tastes great.
