We found what we think will be the answer to most RV'er issues with getting good quality drinking water - every time!
We actually stumbled across it while in a health food store. The company is called Santevia. It isn't cheap, by any means - but, it doesn't require any electricity (reverse osmosis) and it doesn't waste any water.
The resulting taste and ease of maintenance justifies it!
Basically, water filters through it by gravity. It starts out going through a flat ceramic filter (best design!) and then through a 5 stage filter in the lower tank. It also contains small mineral stones in the bottom.
All of this produces great tasting water with the right alkalinity and very simply designed! Take a look at it and a direct link to the company on our website page:
