BWT RO300
BWT RO300
The BWT RO300 is the heavyweight of the under-sink range. Engineered for those who refuse to wait for their water to catch up, this system delivers an incredible flow rate of up to 2 litres per minute. It is a “Direct Flow” powerhouse, meaning it purifies water instantly without the need for a bulky storage tank. For large families or home chefs who require a constant stream of purified water for cooking and drinking, the RO300 is the ultimate high-performance choice.
High-Volume Direct Flow
No tank, no waiting. The RO300 produces pure water in real-time at a speed that rivals your standard tap, ensuring you have an endless supply of purified water even during peak kitchen prep.
99% Contaminant Rejection
High-performance membrane technology. The RO300 strips away fluoride, nitrates, heavy metals, and microplastics.
Space-Saving Design
By eliminating the need for a 10-litre storage tank, the RO300 reclaims your under-sink cupboard space. Its sleek footprint fits easily in modern kitchens.
Automated Membrane Care
Built-in intelligence. The system performs automatic rinsing cycles to keep the Reverse Osmosis membrane in peak condition, ensuring long-term performance and maximum hygiene.

How it Works
Stage 1: Pre-Filtration Refinement
Before reaching the membrane, the water passes through a high-spec carbon block to remove chlorine and organic compounds that can damage the system and affect taste.
Stage 2: Reverse Osmosis Membrane
The water is forced through a semi-permeable membrane. This acts as a molecular sieve, allowing only pure water molecules to pass through while flushing dissolved solids, fluoride, salts, and toxins away.
