The Water Company supplies a comprehensive range of water filter cartridges for domestic, commercial and industrial water purification systems. Our range includes sediment filters, activated carbon cartridges, carbon block filters, specialist filtration cartridges and refillable filter cartridges to suit different water treatment requirements.
Water filter cartridges are an important part of a filtration system. They help remove or reduce specific impurities, protect downstream equipment and improve water quality when correctly selected for the incoming water and intended application.
Whether you need a replacement cartridge for a domestic reverse osmosis (RO) system, a whole-house filtration unit, a commercial water plant or an industrial filtration installation, The Water Company can assist you in finding a suitable filter.
How to choose the correct filter cartridge:
Selecting the right cartridge depends on your water quality, filtration objective and existing filter housing. Before ordering, check the following:
Cartridge dimensions: Confirm the length and diameter, such as 10-inch Standard, 20-inch Standard or Big Blue.
Filter type: Choose the appropriate sediment, carbon, specialist or remineralising cartridge for your application.
Micron rating: Select a suitable particle-retention rating for your system and required flow rate.
Connection and end style: Check whether the cartridge uses a DOE (double open end), SOE (single open end) or another connection arrangement.
Housing compatibility: Make sure the cartridge fits the existing housing.
Water conditions: Borehole water, municipal water and treated RO water can require different filtration stages.
Replacement interval: Follow the manufacturer’s guidance and consider water quality, usage, pressure drop and any change in taste or odour.
For borehole water or other supplies with specific concerns, such as iron, manganese, hardness, nitrates or microbiological contamination, a standard sediment or carbon cartridge may not be sufficient. Water analysis can help determine the appropriate treatment method.
