AP110 Generic Replacement Water Filter Cartridge for AP11S Filter Head, Universal Water Filter Part

AP110 is a generic replacement cartridge made for water filter systems that use an AP11S filter head. It's a straight swap for a spent cartridge, provided your head carries the AP11S marking. Look on the head or the old cartridge for the code before ordering, and if you can't find it or aren't sure, send the details through our parts enquiry form and we'll help match it.

When to change the cartridge in an AP11S filter system

The cartridge does the filtering, while the head simply connects it to the water line. As it works, the cartridge collects whatever it removes from the water, and over time it clogs and loses effectiveness. Signs it's due for a change include a drop in flow from the filtered tap, a return of tastes or smells the filter used to remove, or reaching the change interval recommended for your system. Leaving a spent cartridge in place restricts flow and means the filter does less of its job. Note the date each time you change it.

Changing the cartridge

Close the water supply to the filter and open the filtered tap to release the pressure. Have a towel or small bucket under the head, as some water will drip as the old cartridge comes out. Fit the new cartridge firmly into the AP11S head, turn the water back on slowly and check for leaks. Run water through it for a few minutes before drinking to flush out any fine particles.

Questions about this part

How often should I replace the AP110 cartridge?

That depends on your water quality and how much you use. Follow the interval recommended for your filter system, and change it sooner if the flow drops off or tastes and smells come back. Writing the date on the cartridge helps you keep track.
