Alkaline Remineralizer
An inline post-filter for either BluePeak reverse osmosis system. It adds calcium, magnesium and potassium back to the RO water, which raises the pH slightly and rounds out the taste. $49 installed, as an add-on to an RO system.

What it does
Reverse osmosis strips nearly everything out of the water, including the minerals that give it body, so some people find RO water tastes flat. This cartridge sits inline on the RO line after the membrane and adds a small amount of calcium, magnesium and potassium back as the water passes through. The pH comes up slightly and the water tastes rounder.
It fits both BluePeak reverse osmosis systems, the tank-style and the tankless, and is installed on the same visit. The cartridge is replaced yearly, at the same time as the RO filters.
Who it is for
Anyone who prefers the taste of mineral water over the very clean, very flat taste of straight RO. It is a taste preference: some people strongly prefer it, some cannot tell the difference. If you are not sure, taste the RO water first and add this later; it can be fitted at any time.
It is not a treatment stage. It does not filter anything, and it does not change what the reverse osmosis system removes.
Questions about this system
What’s an alkaline remineralizer and do I need one?
Reverse osmosis removes nearly everything, including beneficial minerals, which leaves the water tasting flat to some people. A remineralizer adds a small amount of mineral content back and nudges the pH up. It’s a taste preference. Some people strongly prefer it, some can’t tell. It’s a $49 add-on on either BluePeak reverse osmosis system, installed inline on the RO line, and the cartridge is replaced yearly.
Tank-style RO or tankless RO — which one?
Both cost the same, $999 installed. Tank-style holds a reserve of filtered water and needs no power, but the tank eats most of your under-sink cabinet and flow drops as the tank empties. Tankless produces on demand at 800 gallons per day, gives you your cabinet back, and doesn’t run out during a dinner party. Both produce excellent water. It’s a space and convenience decision more than a quality decision.
How often do RO filters get changed?
Pre-filters and post-filters roughly annually, the membrane every two to four years depending on your water and your usage. We’ll tell you what your specific system needs and when.
What’s the difference between whole-home filtration and reverse osmosis?
Whole-home treats every drop entering the house — showers, laundry, dishwasher, ice maker. Reverse osmosis treats a small volume very thoroughly at one tap, usually the kitchen sink, for drinking and cooking. They’re complements, not competitors. Whole-home handles chlorine, sediment, iron and smell. RO handles dissolved solids and lead at the tap you drink from. That’s why every whole-home system we sell includes an RO system free.
