Crystal — 5-Stage Under-Sink RO System

Pure drinking water. From your own kitchen tap.

Crystal is a 5-stage reverse osmosis system installed under your sink, delivering purified water through a dedicated tap — removing up to 95% of dissolved solids, heavy metals, chlorine, fluoride, and contaminants from your drinking water.

No bottles. No filter jugs. No compromise. Just pure water, on demand, every day.

What Crystal removes

• Stage 1 — Sediment filter: sand, silt, rust, dirt and particles
• Stage 2 — GAC carbon filter: chlorine, VOCs, bad taste and odour
• Stage 3 — CTO carbon block: chloramines, pesticides, organic chemicals
• Stage 4 — RO membrane: removes up to 95% of dissolved solids, heavy metals, fluoride and bacteria
• Stage 5 — Post carbon & mineral filter: restores beneficial minerals, final taste refinement

3-second filter change — no tools, no plumber

Every Crystal filter uses a quick-change twist design. Lift, twist, pull — done in 3 seconds. No tools, no mess, no service call required.

Replacement schedule:

• Sediment / GAC Carbon / CTO Carbon — every 6 months
