Inside the system
Take a closer look.
Three filtration stages and a vortex conditioner. Keep scrolling to turn the system in your hands.
STAGE 01
Sediment capture
A depth-graded sediment stage strips rust, silt and particulate before it can clog the fine media downstream. The quiet stage that makes every other stage last.
STAGE 02
Taste & odour
A high-capacity granular activated carbon stage absorbs chlorine, chemical impurities and VOCs (volatile organic compounds).
STAGE 03
Catalytic carbon + proprietary blend
The heavy lifter. Catalytic carbon with our proprietary media blend targets chloramine, fluoride, PFAS/PFOS, pharmaceutical residues and VOCs: the contaminants a standard machine filter was never designed to touch.
STAGE 04
Vortex conditioning
The final stage. A precision vortex generator spins water through a stainless helix, designed to help manage scale on your machine's plates and condition water before ionisation.

Your machine's filter does one job.
This does the rest.
The built-in filter is a good chlorine and sediment filter. That is its published spec. A dedicated prefilter addresses what it was never designed to catch.
| Contaminant / feature | Built-in machine filter | Kangen Prefilters system |
|---|---|---|
| Chlorine | Yes, its core job | Designed to reduce >99% |
| Sediment | Yes | Depth-graded capture |
| Chloramine | Catalytic carbon targets it | |
| Fluoride | Designed to reduce >93% | |
| PFAS / “forever chemicals” | Designed to reduce >95% | |
| Heavy metals & lead | Limited | Designed to reduce >98% |
| Pharmaceutical residues | Designed to reduce >96% | |
| Scale management | Vortex conditioning helps manage scale | |
| Replacement cycle | Per machine spec | Once a year, shipped automatically |
Most of what's in tap water is tasteless.
That's the problem.
Chloramine, fluoride, dissolved metals and PFAS don't announce themselves. Water can taste fine and still carry all of them, while hard-water minerals quietly build scale on the plates that make your machine work.

Set it. Forget it.
Stay protected.
$700 once for the complete system. Then $250 a year and fresh filters arrive automatically. Expired media doesn't taste any different, it just quietly stops reducing.
Once a year
A complete replacement set ships every 12 months. Date-stamp the canisters and never think about it.
7-day heads-up
A reminder email lands a week before any charge, with a one-click manage link. No surprise billing.
Fit it yourself
Step-by-step videos, quick-connect everything, anti-bacterial hosing in the box.
Protect the plates
You spent thousands on your machine. Cleaner, lower-scale source water protects that investment.
Cleaner water in.
A protected machine out.
