Common questions
How often do I change the cartridges?
Change the AAL every 6 months and the CBC10 every 6–12 months. Change them sooner if the flow drops. How long the AAL lasts depends on how much fluoride is in your water.
Which take-off valve do I need?
SV3 is a parallel saddle valve for metal pipe. SV6 (G) is a G-clamp saddle valve for polybutylene pipe. SV5 is a Plumbers Delight take-off valve (1/2" BSP). DWTOBV3/4 is a dishwasher take-off tee. Not sure which suits your pipe? Email us a photo and we'll help you pick.
Is a pressure reducing valve included?
No, a pressure reducing valve is not included.
Which tap should I pick?
The TAPD Designer Tap is a chrome high-arch tap with a 10" reach. The PLAT-S is a chrome high-reach single lever tap.

Full product details
Read the full description
A twin undersink filter kit for a dedicated drinking water tap, set up to reduce fluoride. Two 10" Standard housings sit under your sink and feed filtered water to its own tap.
Stage 1 is an AAL activated alumina cartridge that grabs fluoride as water passes slowly through it. Stage 2 is a Pentek CBC10 0.5 micron carbon block that reduces chlorine taste and odour and traps fine sediment. Change the AAL every 6 months and the CBC10 every 6–12 months, or sooner if the flow drops.
Choose your tap (TAPD Designer Tap or PLAT-S Platinum single lever) and the take-off valve that suits your pipe. A pressure reducing valve is not included. If you drink your tank water, pair it with filters plus UV.
We're NZ owned in Te Rapa, Hamilton. If it's not right, we'll put it right.
