I was using the RV CARBON WATER FILTER 40043by Camco for years. I would go through 2 a season, but I was always worried that there would be damage to the filter when I was not using it (unplugged). You definitely know when they expire by the restricted flow rate. Finagling with it during setup/breakdown was an inconvenience. I wanted great water anywhere I went without hauling gallons for bottled water!
After weeks of investigating, I went with a 2 stage Big Blue Whole House Water Filter System KDF55/GAC & SEDIMENT Filters 4.5" x 10" ( 221608555445). These systems are built for homes, so I knew it would last all season long and have not restrictions on flow rates at lower pressures. Found the whole system on Ebay including the 5 micron segment filter and KDF55/GAC filter for less then $100 (kit). Filter changes per season will run $20.
KDF is known to kill algae
, control bacteria
growth, and remove chlorine, pesticides
, organic matter, rust
, unpleasant taste and odor, hydrogen sulfide
, and other organic compounds. Activated carbon filters (GAC) remove/reduce many volatile organic chemicals (VOC), pesticides and herbicides, as well as chlorine, benzene, trihalomethane (THM) compounds, radon, solvents, and hundreds of other man-made chemicals.
I went with a hybrid Activated Carbon and KDF55 filter because the camper would sit for two weeks at a time. Pure carbon filters do not prevent bacterial growth and it would make it unsafe.
I reworked the incoming water line with PEX. I've included two pictures of the installed system under the bed, next to the inlet (including a bypass).
We have used it all season this year and loved the convenience and clarity of our water. One of the best mods to our camper!!!
