Aquaphor K7 | Filter Cartridge

Aquaphor K7 – CarbFiber 0.8 µm final stage cartridge for Aquaphor Crystal filters

The original Aquaphor K7 cartridge is the final purification stage in Aquaphor Crystal, Crystal H, Crystal A, and Crystal HA under-sink filters. It is an ultra-dense block made of pelletized coconut shell activated carbon, combined with modified Aqualen™ fiber, which distributes water evenly throughout the cartridge.

K7 captures particles as small as 0.8 microns and removes substances that passed through the earlier stages: organic compounds, heavy metals, and chlorine. It contains silver in active ionic form, which inhibits bacterial growth inside the filter. The result is clean, odorless water that is suitable for drinking straight from the tap, as well as for coffee, tea, and cooking.

K7 is used in the K3 – K2 – K7, K3 – KH – K7, K5 – K2 – K7, and K5 – KH – K7 sets. It is best replaced at the same time as the other cartridges in the set. Replacement takes a few seconds and requires no tools.

Operating conditions: cold tap water, temperature 5–38°C, pressure up to 6.3 bar.

Recommended replacement frequency: every 3–6 months.
