Extra Plus · Box + Kit
The pH Alkaline Filter is an inline final-stage filter that brings the pH of water leaving the reverse osmosis stage up to around 8.5 and adds minerals to it. It comes with a 2 inch body, its original box and a fitting kit, and is easily added to your existing treatment unit.
01Problem & Solution
Problem
As it separates out dissolved matter, a reverse osmosis membrane also lowers the water’s mineral content. The pH of the outlet water can drift slightly to the acidic side, and some people find the taste flat.
Solution
Added to the line after the membrane, the pH Alkaline Filter brings the water’s pH up to around 8.5 and adds minerals. The water becomes better balanced and softer to drink.
02Key Features
The pH Alkaline Filter is the stage that puts the finishing touch to a treatment system.
Bringing the outlet water to around pH 8.5 gives it a balanced character.
The alkaline mineral bed adds minerals back to the treated water and enriches the taste.
The one-piece inline form fits easily into a tight space under the sink.
Its original box and fitting kit make it straightforward to add to an existing line.
It can be added as a final stage to common under-sink reverse osmosis units.
The one-piece cartridge lets you finish a filter change in short order.

04Applications
The pH Alkaline Filter can be used in any installation where the treated water needs balancing.
05How It Works
The filter is fitted as a final stage on the clean water line leaving the reverse osmosis membrane.
The treated water moves slowly through the alkaline mineral media inside the cartridge.
In contact with the mineral bed, the water’s pH moves towards about 8.5.
The balanced water goes straight to the filter tap or the dispenser outlet.
The mineral bed is used up over time; when the effect on pH weakens, the cartridge should be renewed.
06Making the Right Choice
When choosing the pH Alkaline Filter, the system layout, connection type and what you expect of it should be assessed.
If you want pH and mineral balance, the alkaline filter is the one; if you only want to polish the taste, post carbon will do.
Your unit’s hose diameter and connection type must suit what the kit contains.
There must be enough room under the sink or within the unit for the extra stage.
The alkaline filter goes after the membrane; placing it among the pre-stages is wrong.
07Maintenance and Use
Changed on time, the pH Alkaline Filter keeps doing its job.
