01KITCHEN APPLIANCE ACCESSORIES
Refined clarity for your home water
The quiet workhorse of your kitchen sink, this cartridge sits within the Hydrotap system to transform tap water into a cleaner, more palatable stream. It is the unseen element that ensures every glass you fill tastes crisp and clear.
Designed for homeowners with under-sink filtration, it removes chlorine and odours while retaining beneficial minerals. The Orku Zip 91289 suits those who value precise engineering in their daily routine.

MATERIALS
Carbon and crystal working in tandem
At its core lies a coconut shell activated carbon block, a dense matrix designed to capture chlorine and neutralise unpleasant odours. Paired with a silicon-phosphorus crystal, the cartridge actively works to reduce scale buildup. This dual-material approach addresses both taste and long-term system health without stripping away the natural mineral balance of the water.
PERFORMANCE
Precise flow through a tight tolerance
Operating at a flow rate of 0.5 GPM, or 1.9 litres per minute, the filter balances pressure with purification efficiency. With a 0.5-micron rating, it filters out fine particulates effectively. The system is rated for 300 gallons of capacity, providing a substantial period of refined water before the next maintenance cycle becomes necessary.
COMPATIBILITY
A universal fit for major brands
This cartridge is engineered to slot seamlessly into specific Hydrotap models, including the ZIP 91289, 91291 and 91292. It also maintains compatibility with 3M HF15, HC351 and HC351S units, as well as InSinkErator F701 and Instanta AQ35 systems. Check your existing housing dimensions to ensure a secure seal upon installation.
