Standard CTO Carbon Block Filter

Used after the sediment filter. A polypropylene outer wrap retains fine sediment and protects the carbon block. Made with coal-based activated carbon.

Features

Chlorine, taste and odour reduction through a compressed carbon block
Reduction of organic chemicals
Polypropylene outer wrap gives additional protection against fine sediment
Fewer carbon fines than granular carbon (GAC), no channelling
Coal-based activated carbon; economical, general purpose
Fits standard 10" / 20" housings

Applications

Use after the sediment filter in water treatment systems
Protection of reverse osmosis (RO) membranes against chlorine
Under-sink and countertop filter sets
Drinking and domestic water in residential and commercial buildings
Commercial drinking water points such as cafés, restaurants and dispensers

Use: Disposable, not washable

Shut off the water supply and relieve the pressure in the housing.
Open the housing, remove the used cartridge and clean the housing and O-ring.
Unpack the new cartridge, check the end gaskets, centre it in the housing and close the housing.
Slowly reopen the water supply and check for leaks.
On first use, flush for at least 5 minutes until the water runs clear to remove carbon fines.

CTO cartridges are disposable and must not be washed and reused. Replace the cartridge every 6 months at the latest, or when chlorine taste or odour returns. Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection.
