Every drop of water passes through two advanced filtration stages, each engineered for performance, purity, and longevity.
CBPA Filter – Precision Pre-Filtration
The first stage uses a high-density polypropylene and carbon block composite to capture larger particles like sediment, rust, and suspended matter. It also absorbs chlorine, odours, and organic compounds that affect taste.
Built for consistency, the CBPA filter helps protect the RO membrane from clogging and typically lasts 6–12 months, depending on local water quality.
ROCB Filter – Deep Reverse Osmosis Filtration
At the heart of the system, the ROCB filter combines a reverse osmosis membrane with post-activated carbon to remove up to 99.9% of remaining impurities, including bacteria, viruses, fluoride, heavy metals, and microplastics.
This long-lasting filter delivers pure, great-tasting water with a lifespan of 12–24 months, ensuring sustained performance and peace of mind.
Together, these two filters create a comprehensive purification system that maintains strong flow, reliable hygiene, and an eco-friendly, low-maintenance design, so your water is always clean, safe, and refreshing.
Replacing your filters is quick and effortless. The Veltra PureFlow system is designed with a one-click twist-and-lock mechanism, so you can change filters in seconds, no tools or plumber required.
Simply twist out the old cartridge, click the new one into place, and the system automatically seals and resets. The built-in filter life indicator confirms when it’s time for a change, ensuring you replace it at the perfect moment.
Each replacement set includes everything you need for a complete refresh of your system:
Both filters arrive ready to install, pre-sealed for freshness, and designed to click securely into your Veltra PureFlow system.
