Overview of 3 Step Process- Point of Entry, Softening and Drinking water Purification

Overview of filtering water while RVing.   The first step is to filter the water out of the spigot for sediment, chemicals, chlorine, pesticides, cysts (giardia and cryptosporidium and of course, taste and odor.  This involves a 1 micron sediment filter, followed by a 0.5 micron Carbon block filter.  This step removes most everything that will make you sick, but not all.   Totally dissolved minerals and other elements are still in the water, including calcium and magnesium, which make the water hard

This brings us to Step 2, which is softening the water with a Water Softener.   This removes calcium, magnesium from the water and replaces them with sodium, lowering the pH and saving your RV plumbing from calcification scaling and spotting on your sinks, toilets and showers.

Step 3 will remove the stuff that gets through step 1.  By putting a point of use system under the sink, you can remove bacteria and other potentially harmful elements like fluoride, chloramines, arsenic, lead and heavy metals.   If you choose an under sink RO system, this gives you water that is BETTER than bottled because it won't have the microplastics that remain in bottled water from the bottling process.
