KDF/GAC ‘two-media’ cartridge
Made in America.
Identical to a Microlene 2HK1.
Has built in 1/4″ pushlock speed fittings to fit 1/4 pressure hose. NO tools needed.
Just turn off the water at the inlet valve, disconnect the old cartridge, and push the inlet and outlet hose in to the fittings in the new cartridge.
A Pressure Reducing Valve is recommended for all inline filters: https://www.steamdistiller.co.nz/product/pressure-reducing-valve/
