Best water filter system

Jack Mayer · RV-Dreams Family Member

I also recommend the RV Water Filter Store.

We have a built in whole house dual filter system. The standard size cannisters. We have used them in 4 RVs and I see no reason to go to the Jumbo units, where I can not buy filters at any Home Store. We have sedimentation filter first, then a carbon block filter. That feeds the entire house, and we have no issues at all with flow. If you are getting reduced flow, you need to change filters or get a proper (Watts) water pressure regulator.

After those filters we currently have a reverse osmosis system under the kitchen sink, with its own 3 gallon storage tank. This feeds the sink water dispenser, and the refrigerator water system - we have a residential refrigerator. This setup has proven to work quite well and we will do this in any future coach we build.

Previous to the reverse osmosis filtration system we always had a .5 micron drinking water filter at the sink. This took the place of using bottled water.

Looking to add a replaceable cartridge water filter to our fresh water intake system instead of the single use throw away one I started with. Looking through the forum and googling indicates that short of going the expensive, built in whole house system the optimum idea is something like the FloPur dual cartridge system. The RV Water Filter Store's page does talk about perhaps getting the Jumbo system for full timers due to better flow but we've not noticed any issue with flow using the single disposable cartridge system so I would think that the FloPur POE12DSA1KDF should do the trick nicely. They do admit a much smaller cartridge selection with the Jumbo Canister. RV Water Filter store recommends a #5 and #7 cartridge in the FloPur dual.

Any reason not to go with this or should I investigate the Jumbo or something else as well? At this point I don't anticipate needing anything along the lines of a reverse osmosis system; if we end up in areas with lousy water we'll just use bottled for drinking/cooking and the lousy water for non potable uses. We've got the undersink system that handles the drinking faucet and icemaker/water dispenser in the fridge.

Thanks.

Thanks all, I'll go with the dual cartridge system then. We've got the under sink model for the fridge and drinking water spout on the sink that New Horizons installs as well as a Watts regulator already so that should do the trick for us. Going with the sediment and carbon filters seems to be the most common combination so I won't try to reinvent the wheel there either.

I need to dig through my NH documentation and see what kind of filter I need to get for the undersink fridge filter as well as how long it should last before replacement. I'm guessing it should be good for at least 3 months given the volume it's filtering (ice, maybe a gallon of cold water a week and a coffee pot full daily).

I bought a GE Smart Water filter housing and the necessary hose fittings at Home Depot. The housing cost was about $20 or so. It uses standard size filter cartridges available in most hardware stores. There are many types of filters available - sediment, carbon, carbon block, etc. The 5 micron sediment filters I use cost about 2 for $10. In some places I used carbon ones which cost about $13 for two.
