Materials and Construction

Filter media: Melt-blown polypropylene (PP)
Filtration type: Depth filtration, nominal
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 the line for a few minutes.

The filter is disposable and cannot be opened or washed. Replace it after 9,462 litres or every 6 months at the latest; more frequent replacement may be needed with high-sediment water. Replacing it together with the other pre-filters is recommended.
