Nowadays, many people like to choose to install a small faucet water purifier, which is the same as an ordinary water purifier, mainly through the filter element to filter out some impurities in the water, so as to achieve the effect of water purification. Therefore, when choosing a faucet water purifier, it is mainly the filter element. Below, the editor will introduce the filter element type of the faucet water purifier.
1. Activated carbon filter element
The filter element with activated carbon as the main raw material, 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 different colors and odors in the water, and it can improve the taste of the water. It is a must in the water purifier. One of the filter elements. The service life of activated carbon filter element is generally 6-12 months.
2. Ultrafiltration membrane
The ultrafiltration filter element is made of hollow fiber silk membrane. Its filtration accuracy is about 0.01 microns. It is divided into three categories by the difference of the interface; Korean ultrafiltration filter element, integrated ultrafiltration filter element, and quick-plug ultrafiltration The filter element and ultrafiltration filter element have high precision, so the filtered water is also very clear. Its replacement cycle is generally 10-12 months, except for special water quality special circumstances, due to its different specifications and requirements, if there are special circumstances customizable.
3. PP cotton filter
It is made of polypropylene microfiber material and has three filtering methods: surface, deep and fine. The pore size of the PP cotton filter element is 0.5-100 microns, which can directly filter impurities larger than the pore size in the liquid. The PP filter element is easy to use, and is usually installed in the filter housing! The service life of the PP cotton filter element is generally 3-6 months.
4. KDF filter element
KDF is made of copper-zinc alloy, and its working mechanism is to use electrochemical reaction to remove edema of heavy metals. KDF mainly deals with heavy metal impurities and organic pollution sources in the water. KDF is used at the front of activated carbon, so that 95% of the chlorine in the water is removed by KDF before it reaches the activated carbon; the activated carbon can more effectively remove other impurities remaining in the water .
5. Ceramic filter element
An environmentally friendly filter element, the raw material is mainly diatomaceous earth mud. Diatomaceous earth is recognized as the most effective solid-liquid separation medium in the world. The diatomaceous earth is densely covered with micropores of about 0.3 microns, which will reduce the ultrafine diatomite The soil is extruded and sintered at a high temperature to form diatom ceramics with a thickness of about 10mm, which is equivalent to forming a filter with a pore size of 0.3 micrometers composed of 1,000 layers of ultrafine diatomaceous earth. Harmful substances and bacteria are isolated in the outer layer of the ceramic, so as to achieve the purpose of purifying water quality. The ceramic filter element can be repeatedly cleaned and used. The normal number of times 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 it can be used for 3-5 years or even longer.
6. Ceramics and nano-KDF
Water purification technology based on the built-in ceramic filter element and nano-KDF filter material (NMC), the water flow is greater than that of the water purifier using hollow fiber technology. The ceramic filter element can be repeatedly cleaned and used. After a certain service life, it needs to be replaced regularly Filter element. Among them, the nano-KDF filter material (NMC) does not have the phenomenon of bacterial growth during the use of activated carbon and long-term use of KDF, which is easy to compact and increase resistance, and has been widely used in the field of water purification.
The above is the introduction of the six types of filter elements of faucet water purifiers. When purchasing a water purifier, our main thing is to see whether the product filter element meets our needs, and the same is true for faucet water purifiers.
