Replacement filter kits for the Aquaphor RO-206S series are designed to maintain stable performance in a reverse osmosis system for home, office and HoReCa. The kit contains K1, K2 and RO-150S membrane, with a membrane capacity of up to 568 liters per day, equivalent to 23.7 liters per hour or 150 GPD. It provides documentable filtration steps that reduce particles down to 3 microns and contribute to the removal of chlorine, heavy metals, nitrates, bacteria and viruses.

Compared to simpler water filters that only use one carbon stage, this kit combines mechanical filtration, activated carbon, AQUALEN fiber and reverse osmosis in several separate purification stages. It provides both better protection of drinking water quality and effective reduction of lime-forming salts that can burden coffee machines, kettles, steam ovens and other equipment.

• K1 combines mechanical filtration and activated carbon in two zones, reducing iron ions and coarse particles down to 10 microns before finer filtration down to 3 microns.
• K2 uses CarbFiber Block technology and modified ion exchange AQUALEN fibers to reduce active chlorine, organic compounds and heavy metals.
• The RO-150S membrane filters microscopic impurities and has a capacity of up to 568 liters per day.
• Helps reduce lime, odor and chlorine taste, which provides cleaner water for drinking, cooking, coffee and tea.
• Fits the Aquaphor RO-206S series and similar HoReCa solutions where consistent water quality is important in daily operations.

The K1 filter acts as the first barrier in the system. The first filtration zone reduces Fe2+ and Fe3+ as well as larger particles such as sand, rust and sediments. The second zone uses activated coconut carbon and AQUALEN fiber to reduce finer particles, heavy metals, drug residues and pesticides. This combination is particularly relevant in areas with varying water quality or where the drinking water is used in equipment that is sensitive to deposits and impurities.

The K2 filter provides deeper purification of the drinking water before the water reaches the membrane. The CarbFiber Block structure provides a tight contact surface for organic matter and chlorine, while AQUALEN fibers contribute to the irreversible binding of heavy metals. This is an important difference from standard charcoal filters, which often have more limited control over dissolved contaminants over time. The result is more stable water quality and a reduced load on the subsequent membrane.

The RO-150S is the main stage of reverse osmosis and is designed to remove scale-forming salts as well as very small contaminants such as nitrates, nitrites, fluoride, bacteria, viruses, antibiotics and hormones. For users in HoReCa, in the office or in homes with high water consumption, this means water that is better suited for both drinking and cooking, while at the same time the lifespan of appliances can be improved. In coffee shops and professional kitchens, a reduced lime load can also contribute to a more predictable taste and less maintenance.

This filter kit is an important maintenance point for Aquaphor RO-206S systems. When the filters are changed according to the recommended interval, cleaning efficiency, water quality and protection of connected equipment are maintained. For those who want a compatible replacement filter with several filtration stages, clear technical specifications and suitability for both domestic and commercial use, this is a precise solution for reliable water purification.
