The change schedule of cartridge is totally based on water condition and purified water
consumption, if the cartridge was changed on a regular basis, it will ensure the proper
operation of filter machine and the quality of purified water. Therefore, the recommended
change schedule of cartridge is only for reference.

1. If the high cistern was installed on the roof, since the cistern is out of clean, it will
cause many sediment and dirt, in the case like this, please change the cartridge more
often.
2. TDS increased indicates the quality of purified water is getting down, please check and
confirm if the post carbon filter need a replacement or the RO membrane is failure.
3. The post carbon is set for increasing taste, if the taste of purified water feels bad,
please change the post carbon cartridge, otherwise the bacteria are easy to breed and
affect the safety of drinking water.
