Premium Triple Undersink System — Doulton Ultracarb
This premium model is ideal in areas prone to boil water alerts. The Doulton Ultracarb cartridge is bacteria-rated and, paired with dual carbon stages, produces exceptionally clear, safe-tasting water. Using both coal-based and coconut-husk carbon means complementary treatment strengths and longer contact time for highly effective filtration.
Why Choose This System?
- Bacteria-rated ceramic core — 0.5 micron nominal; removes 99.9996% of E. coli and controls Giardia & Cryptosporidium cysts (Ultracarb).
- Dual carbon blend — coal + coconut stages target a wider range of tastes, odours and chemicals.
- Serviceable ceramic — Doulton Ultracarb is cleanable to extend life and performance.
- Quality housings — Quality 10″ housings, tested to AS 3497.
- Includes PLV with dual checks — 550 kPa WaterMark AS1357-2 valve supplied (code requirement).
- Complete kit — supplied ready for installation.
How It Works: 3-Stage Filtration
- Stage 1 — 1 micron polyspun removes sediment (dirt, rust, sand) to protect downstream filters.
- Stage 2 — Doulton Ultracarb (ceramic/carbon) 0.5 micron bacteria-rated ceramic with carbon block and heavy-metal media; colour, taste & odour reduction; cyst control; cleanable surface.
- Stage 3 — Omnipure coconut carbon block polishes taste and adsorbs residual organics for crisp, fresh water. (Ultracarb rated to ~30,000 L under lab conditions.)
Town water only: Not suitable for unchlorinated supplies (e.g., untreated rainwater, bore water).
