Pure Alkaline Filter
Puts the good minerals back after RO takes everything out.
Reverse osmosis is thorough — it strips beneficial minerals along with the contaminants. The alkaline filter adds calcium and magnesium back in, which is what makes water taste like spring water instead of flat. Pairs with either RO system.
Best for: Anyone who finds plain RO water tastes flat
