Ensure a constant flow of clear, healthy and tasty water with the professional Waternoble filter set from BEILIN H2O.
This set is designed for periodic replacement in under-sink filtration systems and home reverse osmosis systems. It provides deep, multi-stage filtration that significantly improves water quality and serves as the first line of defense for your systems. The set fits housings in the standard global size (10 × 2.5 inches).
The three filtration stages in the kit:
Stage 1: PP Cotton (polymer cotton): efficient physical filtration of suspended particles, coarse dirt, sand, rust and turbidity in the water (5-micron filtration level).
Stage 2: UDF (granular activated carbon): powerful absorption of free chlorine, chemicals and pesticides, and removal of odors and off-tastes from the water.
Stage 3: CTO (compressed activated carbon – block): deep micron filtration giving double protection, improving the water's color and taste and preventing tiny carbon particles from passing further into the system.
Key advantages
Efficient filtration: removes up to 99% of chlorine, sediment and physical contaminants in the water.
Universal compatibility: fits all standard 10" filter housings on the market (under-sink and osmosis systems).
Membrane protection: serves as a pre-filter that prevents clogs and preserves the life of your osmosis membrane.
Works on natural pressure: operates using the existing water pressure in the plumbing – no electrical connection needed.
Simple maintenance: quick, convenient installation.
Long lifespan: 4 to 6 months of peace of mind and clean water per set (depending on local water quality and consumption rate).
Note: the set does not include an osmosis membrane or mineralizer (available separately at BEILIN H2O).
