2" Inline Alkaline Extra Filter

Reverse osmosis water is usually slightly acidic and low in TDS. The alkaline filter raises the pH, slightly increases TDS and lowers the ORP.

Features

Raises the pH of reverse osmosis water
Adds calcium, magnesium and potassium to the water
Lowers ORP
Label capacity of 7,571 L (2,000 gal)
Tool-free, quick replacement with quick-connect stems
Fits standard 2" inline filter positions

Applications

Residential reverse osmosis (RO) units
Under-sink and countertop water purifiers
Add-on filter for existing RO units
Mains-fed (bottleless) water dispensers
Office and small commercial treatment systems

Connection: Quick-connect stems 4/6, both ends
Use: Disposable, sealed

Shut off the unit's water supply and open the faucet to relieve pressure.
Install the filter between the membrane outlet and the tank inlet.
Connect the quick fittings, observing the flow direction on the housing (IN → OUT).
Slowly reopen the water supply and check the connections for leaks.
On first use, flush at least 12 litres of water to drain.

The filter is disposable and cannot be opened or washed. Replace it after 7,571 litres or every 12 months at the latest; the pH effect decreases over its service life. It is not a medical product. Do not use with microbiologically unsafe water or water of unknown quality without disinfection.
