1、 Clearly define filtering requirements

Water quality analysis: Firstly, it is necessary to understand the water quality of the water to be filtered, including the types and concentrations of impurities contained, as well as possible microbial contamination. This helps determine the required filtration accuracy and filter cartridge type.

Purpose determination: Clarify the purpose of the filter element, whether it is used for drinking water filtration, industrial water treatment, or other specific fields. Different applications have different performance requirements for filter cartridges.

2、 Filter type selection

PP cotton filter: suitable for removing small particles and impurities in water, such as sediment, rust, suspended solids, etc. Its price is low, but the filtration accuracy is relatively low and needs to be replaced regularly.

Activated carbon filter: mainly used to remove odors, residual chlorine, and organic matter from water. Activated carbon has strong adsorption capacity, but it will gradually become saturated and needs to be replaced regularly.

Ultrafiltration filter: capable of removing tiny particles such as microorganisms, bacteria, viruses, etc. from water, suitable for direct drinking water treatment. The filtration accuracy of ultrafiltration filters is relatively high, but the price is also relatively expensive.

RO reverse osmosis filter: It is currently one of the most widely used water purification technologies, capable of removing the vast majority of impurities in water, including heavy metals, bacteria, viruses, etc., and producing pure water that can be consumed directly. But its price is relatively high and requires a certain amount of water pressure support.

Titanium rod filter element: It has the characteristics of corrosion resistance, high temperature resistance, antibacterial and antioxidant properties, and is suitable for occasions with high water quality requirements. But its price is relatively high, and the appropriate filtration accuracy needs to be selected according to the specific water quality situation.

3、 Consider other factors

Filter material: The material of the filter directly affects its performance and lifespan. Stainless steel, titanium alloy and other materials have excellent corrosion resistance and high temperature resistance, but their prices are relatively high; Plastic and other materials have lower prices, but may not be heat-resistant or prone to aging.

Filtering accuracy: Choose the appropriate filtering accuracy according to actual needs. The higher the filtration accuracy, the more impurities can be removed, but it may also lead to slower water flow rate and shorter filter life.

Brand and Certification: Choosing well-known brands and certified filter products can ensure that their quality and performance meet standards. Meanwhile, branded products typically have better after-sales service and warranty policies.

Cost and benefit: Taking into account factors such as the price, service life, and filtration efficiency of the filter element, choose products with high cost-effectiveness. At the same time, factors such as replacement and maintenance costs of the filter element also need to be considered.

4、 Summary

When choosing a filter cartridge, it is necessary to clarify the filtration requirements, select the appropriate type of filter cartridge, consider factors such as filter cartridge material, filtration accuracy, brand and certification, as well as cost and efficiency. By considering these factors comprehensively, one can choose the filter cartridge product that best suits their needs.
