Adsorption with granular activated carbon
Reduces chlorine, taste, odour and dissolved organics
Protects the reverse osmosis membrane from chlorine
Sealed housing; no housing cleaning needed at replacement
Tool-free, quick replacement with quick-connect stems
Fits standard 2.5" inline filter positions

Applications

Residential reverse osmosis (RO) units
Membrane-free UF water purifiers
Under-sink and countertop water purifiers
Mains-fed (bottleless) water dispensers
Office and small commercial treatment systems

Dimensions

A: Overall length (including connection stems) · B: Outer diameter. Sealed (welded) housing; the filter cannot be opened and is replaced as a unit. Flow direction is marked on the housing.
* Label value (2,500 gal). Actual capacity depends on water quality, chlorine level and flow rate.

Operating Conditions

Operating pressure: 1.4 - 8 bar (20 - 116 psi)
Operating temperature: 4 - 38 °C (39 - 100 °F)
Maximum flow rate: 2.8 L/min (168 l/h)
Replacement interval: 9,462 L or 6 months max.

Materials and Construction

Filter media: Granular activated carbon (GAC)
Carbon source: Coal-based activated carbon
Housing: Plastic (typically PP), welded
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.
Detach the used filter from its connection stems and remove it from its clip.
Connect the new filter, observing the flow direction on the housing (IN → OUT).
Slowly reopen the water supply and check the connections for leaks.
On first use, flush for at least 5 minutes until the water runs clear to remove carbon fines.

The filter is disposable and cannot be opened or washed. Replace it after 9,462 litres or every 6 months at the latest; replacing it together with the other pre-filters in the system is recommended. Do not use with microbiologically unsafe water or water of unknown quality without disinfection.
