Media material is from Coconut fibre, vastly superior to charcoal carbon, with superior life and reduced channeling.
Usually the first filter in a filtration system designed for typical water quality, that contains a normal amount of debris, evidenced by plugging at 6 to 9 months.
Premature Plugging can occur during 'high pollen'. The pollen clogs the papers pores but is difficult to see. The paper otherwise looks clean enough...
Can be washed.
When fittings always relubricate the sump Oring and threads, to enable sealing from hand tightening the sump. This avoids flattening of the Oring due to 'overtight'.
Always purge before finishing your systems cartridge change, to avoid unnecessary air spurting through your household taps.
Sumps tighten from the effect of water pump pulsation.
