Keep your SustainWater gravity filter working with a fresh set of two ceramic activated carbon replacement filters.
These replacement filters are designed for households that already use the SustainWater stand filter and want a simple way to continue everyday filtration without electricity, plumbing or disposable plastic bottles.
What these replacement filters are for
The ceramic and activated carbon filter design is intended to support everyday drinking-water filtration by helping reduce common taste, odour and sediment concerns.
They are designed for:
- replacing used filters in your SustainWater stand filter
- everyday kitchen water filtration
- reducing chlorine taste and odour concerns
- helping with rust, sediment and visible particles where suitable
- keeping your gravity filter system ready for regular use
Key specifications
- Includes 2 ceramic activated carbon replacement filters
- Listed filter life: up to 6,000 gallons
- Estimated use period: up to 12 months, depending on water quality and usage
- No electricity required
- No tools required for normal replacement
- Designed for use with the compatible SustainWater gravity stand filter
The filter life estimate depends on the water being filtered. Higher sediment, stronger taste/odour, visible discolouration, or heavier use can reduce practical filter life.
How to use
Pre-soak and install the filters according to the instructions supplied with your filter system. Once fitted, fill the upper chamber, allow the water to pass through the filters, and discard the first filtered water if instructed before normal use.
For best results, keep a note of when the filters were installed and replace them when flow rate, taste, odour, usage time, or the product instructions indicate it is time.
What filtration can and cannot tell you
A filter can help improve everyday water taste and filtration, but it does not tell you what is present in your water. If you are trying to understand a specific concern such as lead, bacteria, arsenic, chlorine or fluoride, start with a suitable water test rather than guessing from taste alone.
If you are not sure which test fits your concern, use our Which Water Test Do I Need? guide. You can also compare local context on the UK water testing map.
Useful next step
If you are replacing filters because your water tastes, smells or looks different, read our Taste & Smell Problems guide before assuming filtration alone is the right answer.
