The filter element in pure water equipment is used to block impurities in water, but after prolonged use, blockage or incomplete filtration may occur. It needs to be replaced in a timely manner. How to determine its replacement time?

When the water resources are "rivers" or "streams", the water body can be regularly maintained and the filter element can be replaced based on the water quality monitoring results.

When water resources come from "surface water" and the water content of iron is too high, the time for replacing filter cartridges can be reduced by one month or reduced based on the water body.

When the water resource is "drinking water", the time for dismantling and replacing different filters varies. PPF chemical fiber filters are usually dismantled and replaced between March and June. The water purification activated carbon filter element or small activated carbon filter element will be replaced from June to December. The reverse osmosis membrane of the pure water equipment ROro will be disassembled and replaced from 24 to 36 months. The activated carbon filter element of the rear camera is usually replaced every December.
