Clean, Toxin-Free Water. Without The Hassle.
Most under-sink filtration systems require drilling, a separate tap and a lengthy installation process that usually means calling in a tradesperson. The Frontline Under-Sink Filter is different. It clips into your existing cabinet, connects directly to your cold water valve and your kitchen tap, and is ready to use in minutes. No drilling, no extra holes, no professional required.
Clean, filtered water on demand for drinking, cooking, rinsing produce and filling water bottles. All from the tap you already use every day.

Frontline Filtration vs. A Standard Filter.
Most filters on the market do the basics. They reduce some chlorine, catch some sediment, and call it clean. Frontline’s multi-barrier filtration goes further, targeting a wider range of contaminants with greater surface area and longer lasting performance.

Tastes like high-end bottled spring water
“We live in an older Sydney apartment with aging copper pipes. The metallic chlorine taste disappeared instantly after installing Frontline Ultra-12. Water flow is super fast.”
Renter-friendly dream. Took 10 mins
“Did not have to drill a single hole in the stone benchtop. Screwed directly into our mixer tap cold hose under the kitchen sink. When our lease ends, we'll pack it up in 5 minutes.”
Compact and super neat
“Takes up almost zero room beside our pull-out bin. The smart LED at the bottom is awesome peace of mind so my partner and I don't have to keep a calendar reminder.”
