PAC composite composite filter (folding PP cotton + high-density sintered carbon block) (5μm) The first stage of the PAC filter uses folding PP cotton, which offers far more surface area than standard flat PP cotton found in most filters. More folds = larger contact area + higher dirt-holding capacity.This means it captures more rust, silt, and fine particles, thus lasting longer and less clogging—giving your system a stronger and cleaner start.
This stage uses a high-density sintered carbon block to deliver cleaner and more consistent pre-filtration. Its compressed, uniform structure captures finer chemical residue more effectively than loose carbon granules. The result is better chlorine reduction, fewer VOCs, and a smoother, fresher taste — ensuring the RO membrane receives cleaner water for deeper purification.

Stage 3 — NanoFlow™ Reverse Osmosis
RO Filter (Reverse Osmosis) (0.0001μm)
NanoFlow™ uses an upgraded 0.0001-micron membrane that removes up to 99.9% of dissolved impurities, delivering cleaner, safer water in every drop. It provides a faster flow and more stable purification — without relying on chemical scale inhibitors like many traditional RO systems. An automatic self-cleaning flush rinses the membrane regularly, maintaining peak performance and reducing build-up. The result is purer water, a longer-lasting membrane, and a more natural, healthy, and eco-friendly filtration process.

Stage 4 — Post activated coconut shell Carbon
CF filter (post Carbon)
The post-Carbon stage uses high-density coconut-shell activated Carbon, valued for its superior microporous structure compared to coal-based Carbon. More micropores = stronger adsorption and a cleaner final taste. It effectively removes residual chlorine, VOCs, and any remaining odours, ensuring the final output tastes fresh, crisp, and naturally smooth—the perfect finishing touch before the water reaches your glass.

Stage 5 — UV sterilisation
UV chamber (99.9% sterilisation) The UV chamber keeps purified water at its freshest — clean, bright, and crystal-clear. By neutralising bacteria and protecting the sealed tank from re-contamination, the purity you get at the RO stage is the purity you taste. Smooth, safe, and mountain-spring fresh—water held at its very best.
Five stages. One perfect taste — clean, bright, and refreshingly pure, just as water was before human pollution. The way nature intended.
