Replacement filter cartridges matched to Olympus units in London
Seven cartridge types. Main filters last around one year. Standard and Giga sizes available.
Restore an Olympus unit with model-matched ceramic, softening, nitrate, tap or shower refills.
Keep flow and filtration working as intended
A used cartridge can gradually affect water flow and filtration performance, so timely replacement is part of keeping your Olympus system useful. Our replacement filter cartridges include ceramic, Giga ceramic, softening, Giga softening, nitrate-removal, mini tap and shower options. The correct choice depends on the complete filter model and the media already fitted. Look for a model name, product record or details from the previous refill before ordering. A similar-looking cartridge isn't always compatible with the housing, seal or intended use.
Plan changes around use and water conditions
Around one year is stated for the main filters, but actual timing depends on the model, water consumption and incoming water conditions. Higher use may bring the replacement point forward, while changes in flow can also indicate that the cartridge needs checking. Prepare a clean working area before opening the housing and handle the new refill hygienically. Once fitted, restart the water supply carefully and follow the product guidance for flushing. We supply the refill, while you remain responsible for fitting it correctly.

Questions and answers
How often should an Olympus cartridge be replaced?
The main filters are stated to last around one year, but timing varies with consumption, water conditions and the model in use. Check the product guidance and note any meaningful reduction in flow when planning a change.
How do we identify the correct replacement cartridge?
Check the name or model information on the Olympus unit and identify the existing media type. A photo or previous order record may also help. Don't select a refill by appearance alone because sizes and purposes differ.
What should we do after changing a cartridge?
Secure the housing as directed, restore the water supply slowly and check the connection for leaks. Follow the product's flushing guidance before normal use, and record the change date to make future planning easier.
