Water quality situation

Good water qualityIf household water comes from high-quality water sources with low levels of organic matter, residual chlorine, and other impurities, and the adsorption saturation of the pre activated carbon filter increases slowly, the replacement cycle can be appropriately extended, usually every 8-12 months. For example, some municipal water supply areas that originate from deep and high-quality groundwater and have been well treated.

Poor water qualityIf there are many pollutants in the water, such as tap water from old pipelines or untreated surface water, the adsorption burden of the pre activated carbon filter is heavy, the saturation rate is fast, and it may need to be replaced in 3-6 months. Water quality in areas with severe industrial pollution, or non centralized water supply sources in some rural areas.

Water consumption size

Small household size and limited water usageIf the household has a small permanent population, the daily consumption of drinking water and other household water is not large, the frequency of use of the filter element is low, and it takes a long time for its adsorption to reach saturation, the replacement cycle can be extended to about 10-12 months.

Large household size and abundant water usageFor households with a large population or in situations where there is a high demand for water, such as frequent cooking, brewing of tea, and fish farming, the filter element will quickly reach adsorption saturation and may need to be replaced within 3-6 months.

Filter cartridge specifications and brand

Large filter cartridge specificationsSome large-sized pre activated carbon filter cartridges are filled with a large amount of activated carbon and have a relatively large adsorption capacity. Under the same water quality and water consumption conditions, their service life may be longer than that of small-sized filter cartridges, and they may take 8-12 months to replace.

Small filter sizeThe activated carbon filled in small-sized filter cartridges is limited, with relatively weak adsorption capacity and fast saturation rate, and may need to be replaced in 3-6 months.

Brand and quality differencesDifferent brands of activated carbon filters have varying adsorption performance and service life due to differences in production processes and activated carbon quality. High quality brand filter cartridges, using high-quality activated carbon and better manufacturing processes, have high adsorption efficiency and long service life, with relatively long replacement cycles; Filter cartridges with average quality may require more frequent replacement.
