Purity water purifiers comes with an automatic filter change indicator.
The continuous volume control LED light will blink, when it is time to change the filters.
Alternatively, we recommend for an average Singaporean household to change the filters once per year, as our water filters are designed to last 5000-6000 litres, good for families below 5 pax, more frequent replacements will be required for larger families.
