After you have installed the whole RV system in Step 1 to get out the bulk of the floating sediment, contaminants and cysts like giardia, and removed the calcium and magnesium in step 2 – water softening, you may still want to purify the water further with a drinking water system. Our Ultrapure Premium Under Sink system uses an awesome filter called the D-UC on our store. It is from Aquacera, and it has a ceramic outer shell with a carbon block core. This would be great for a whole RV system if not for one thing-The flow slows down when you get to this level of filtration. You can see this from the counter top systems where it takes several minutes to filter a pitcher of water.
This filter removes all bacteria, literally 99.9999% of them. It also removes lead, heavy metals, arsenic, chloramines, fluoride, and a bunch of other things for the purest water this side of reverse osmosis. It still has totally dissolved minerals in the water, so it isn’t acidic like RO, but has a neutral pH and still has the beneficial minerals in the water.
This system comes with a separate faucet and uses a simple to install standard canister. The separate faucet is needed because the flow is about 1 gallon/minute, and may be too slow for your cold water supply to the sink. The good news is that you can use it real time vs storing in a tank or a pitcher of water, and the water coming out of the sink will be excellent.
