Composite filter element:
Composed of various different filter materials, which may include ceramic filter cartridges, ultrafiltration membranes, etc.
It can simultaneously filter various impurities and pollutants, such as sediment, rust, residual chlorine, etc.
It can effectively remove odors and discolored substances in water, and improve water quality.
Usually used in most water purifiers on the market, the pre-treatment filter element is placed in the pre filter.
Compared to activated carbon filters, composite filters have a lower odor removal effect than activated carbon filters.
The general service life is relatively long, about 6-12 months.
The price is relatively high, but considering its better filtering effect and longer service life, it is usually considered to have a higher cost-effectiveness.
Activated carbon filter element:
Mainly filled with granular activated carbon.
It has a good removal effect on organic compounds, heavy metals, residual chlorine, etc. in water.
The filtered water has a better taste and is suitable for places with high requirements for water odor and odor treatment.
Suitable for treating areas with poor water quality, it can effectively remove odors, organic matter, and residual chlorine from water.
Due to the main reliance on the adsorption of activated carbon, it is impossible to filter out small particles such as mud, rust, etc.
It needs to be used in conjunction with other filters to handle these small particles.
The service life is relatively short, usually between 3-6 months, so it needs to be replaced more frequently.
The price is relatively low, but due to frequent replacement, the cost may be higher in the long run.
