As people care more and more about their health, it has also reflected a lot in terms of water use. The filter element of the water purifier is generally full of KDF and activated carbon. The filter element is to clean the damaged water to the state required for production and life, that is, to make the water reach a certain degree of cleanliness. Remove solid particles in water, eliminate germs, and filter out harmful components. The compact household water purifier mainly uses the filter element to filter out some impurities in the water to purify the water quality, so when choosing a household water purifier, it mainly depends on the filter element.
1. Activated Carbon Filter Element
Activated carbon is the main raw material of the filter element. The filtration accuracy of the activated carbon filter element is not as high as that of the PP filter element, but its own advantage is that it has a good adsorption effect on the color and odor in the water, and can improve the taste of the water quality. It is a must in the water purifier. One of the filters. The service life of activated carbon filter elements is generally 6-12 months.
2. Ultrafiltration Membrane
The ultrafiltration filter element is made of hollow fiber silk membrane, and its filtration accuracy is about 0.01 micron. It is divided into three types according to the interface; Because of the high precision of filter element and ultrafiltration filter element, the filtered water is also very clear. Its replacement cycle is generally 10-12 months, except for special water quality and special circumstances. Due to its different specifications and needs, if there are special circumstances customizable.
3. PP Cotton Filter Cartridge
Made of polypropylene microfiber material, there are three types of filtration: surface, deep, and fine. The PP cotton filter cartridge has a pore size of 0.5 microns to 100 microns, which can directly filter impurities larger than the pore size in the liquid. The PP filter element is easy to use and is generally installed in the filter housing! The service life of the PP cotton filter element is generally 3-6 months.
4. KDF Flter Element
KDF is made of copper-zinc alloy, and its working mechanism is to use electrochemical reaction to remove heavy metals from edema. The main object of KDF treatment is heavy metal impurities and organic pollution sources in water. KDF is used at the front end of activated carbon, so that 95% of the chlorine in water has been removed by KDF before reaching activated carbon; so that activated carbon can more effectively remove other impurities remaining in water .
5. Ceramic Filter Element
An environmentally friendly filter element, the main raw material for production is diatomite mud. Diatomite is recognized as the most effective solid-liquid separation medium in the world. Diatomite is densely covered with micropores of about 0.3 microns. Ultrafine diatomite After extrusion and high-temperature sintering, diatom ceramics with a thickness of about 10 mm are formed, which is equivalent to forming a filter net composed of 1,000 layers of ultra-fine diatomite with a pore size of 0.3 microns, and more than 99% of tap water is larger than 0.3 microns. Substances and bacteria are isolated on the outer layer of ceramics, so as to achieve the purpose of purifying water quality. The ceramic filter element can be cleaned and used repeatedly. The normal number of brushing is 20-28 times. There is no secondary pollution and the water output is large. The filter element can generally be used for 10-12 months, and the good one can be used for 3-5 years or even longer.
6. Ceramic and Nano-KDF
Water purification technology based on membrane built-in ceramic filter element and nano-KDF filter material (NMC), the water flow rate is greater than that of the water purifier using hollow fiber technology, the ceramic filter element can be cleaned repeatedly, and needs to be replaced regularly after a certain service life filter element.
Among them, nano-KDF filter material (NMC) has no bacteria growth during the use of activated carbon and KDF is easy to harden and increase resistance after long-term use, and has been widely used in the field of water purification.
