If there is a consistent pursuit of life among people nowadays, it must be health. Drinking water health is an important aspect of people's pursuit of healthy life. With the development of science and technology, water purifiers have gradually become the first choice for ensuring the safety and health of household drinking water. Although the penetration rate of water purifiers is getting higher and higher, do users really understand water purifiers?

It should be known that after the water purifier is used for a long time, the adsorption of the filter element will reach a saturated state, then the filter element needs to be replaced at this time. So what are the water purifier filters? And what are the replacement points of different water purifier filters? Today, the editor of AICKSN brought the most complete popular science of the water purifier filter element. As long as you understand this knowledge, you can easily grasp the water purification effect of the water purifier!

1｜PP cotton filter

PP cotton filter is also called polypropylene meltblown filter. Pretreatment, large filter area and dirt holding capacity.

Uses: filter out sediment, rust, floating matter, colloid, organic matter, impurities, etc. in water.

Reference replacement cycle: 3-6 months

2｜Activated carbon filter

There are three main types of activated carbon filters: granular activated carbon filters, compressed activated carbon filters, and post-installation antibacterial activated carbon filters.

1) Granular activated carbon filter element: Generally, coconut shell, nut shell and coal are used as raw materials, and are refined by special process. They have pore structure and good adsorption performance. They are often used as secondary filtration of water purifiers.

Uses: It can remove organic matter, peculiar smell and color in water, such as pesticides, residual chlorine, chloroform, etc.

2) Compressed activated carbon filter element: It is made by mixing granular activated carbon powder material and inorganic liquid binder, pouring it into a special mold, compressing it with a press at high pressure, and drying it after being released from the mold. It has stronger filtering ability and longer service life than granular activated carbon, and is often used as the three-stage filtration of water purifiers.

Uses: Deeply absorb the odor, color, residual chlorine and organic substances in the water that are harmful to the human body, and effectively improve the taste of the water.

3) Post-installation antibacterial activated carbon filter element: It is a new type of deep filter filter element, which is composed of high-quality coconut shell activated carbon and low thermal melting adhesive. Some high-quality post-activated carbon filter materials are treated with silver, and silver atoms can sterilize and inhibit bacteria, and are often used as the last filter element.

Uses: To further remove odor, residual chlorine and bacteriostasis, prevent secondary pollution of purified water, and make the water taste fresher and sweeter.

Reference replacement cycle: half a year - 1 year

3｜Ultrafiltration filter element

The ultrafiltration filter element is made of polypropylene hollow fibers with a pore size of about 0.1-0.01 microns.

Uses: Intercept extremely small suspended solids, colloids, particles, viruses, bacteria and other harmful substances in water, and filter out macromolecular substances in water.

Reference replacement cycle: 2-3 years

4｜Ceramic filter element

The ceramic filter element is made of diatomite by molding and sintering at high temperature. It has a pore size of 0.1 microns. Its purification principle is similar to that of activated carbon.

Uses: It can effectively filter out sediment, rust, some bacteria and parasites and other microorganisms in water.

Reference replacement cycle: half a year - 1 year

5｜Reverse osmosis membrane

The reverse osmosis membrane is made of cellulose acetate or aromatic polyamide, etc., with a pore size of 0.0001 microns. Because of its small pore size, it is easy to be blocked by impurities and lose its function. In order to prolong the service life of the RO membrane, pp cotton and activated carbon should be used. After filtering and preprocessing, it is generally used in the fourth level.

Uses: Effectively remove colloids, microorganisms, organic matter, heavy metals, bacteria, viruses, pesticides and other substances in water, while allowing only water molecules to pass through.

Reference replacement cycle: about 3 years

6｜Other filter elements

Ion exchange resin filter element: It can be divided into two categories: cation resin and anion resin, which can ion exchange with cations such as calcium and magnesium and anions such as sulfate in water to achieve softening and deionization of hard water, but it cannot filter bacteria and viruses. and other impurities.

Heavy metal filter element: such as KDF filter element, it is a high-purity copper and zinc alloy filter material, which can effectively remove heavy metals such as lead, mercury and other harmful heavy metals in water, as well as chemical pollutants such as chlorine and organic matter, and release them at the same time. Zinc that is beneficial to the human body.

Reference replacement cycle: ion exchange resin filter element for half a year, heavy metal filter element for 2-3 years

However, the recommended life cycle of the filter element is not the only criterion for judging the replacement of the filter element, because the water quality of different regions is different, and the service life of the filter element will be different accordingly. Therefore, AICKSN Xiaobian reminds you that you should consider replacing the filter element in time if the water purifier at home has the following conditions:

1. The effluent flow is significantly reduced and cannot meet the normal use needs, indicating that the filter element is blocked. At this time, the filter element should be cleaned. If the filter element cannot return to normal flow after cleaning, it is recommended to replace the filter element.

2. The taste of the effluent has decreased, and it is close to the tap water, indicating that the chlorine smell in the tap water has not been removed, indicating that the activated carbon filter element has been saturated with adsorption and has lost its effectiveness, and the filter element needs to be replaced.

3. The phenomenon that the water effluent is obviously accelerated. This situation is generally caused by the damage of the reverse osmosis filter membrane. It is necessary to replace the new reverse osmosis filter membrane, otherwise the filtration function will be lost.

4. If you are in an area with serious water pollution, the service life of the filter element will definitely not reach the specified time. It is recommended to replace the filter element when the service time reaches about 80% of its ideal life.

In order to improve the user experience, many water purifier manufacturers are optimizing the operation of filter replacement, allowing users to replace the filter independently. So how do you usually replace the filter? AICKSN Xiaobian believes that it is generally divided into the following steps:

1. First close the water inlet ball valve to empty the water in the machine;

2. Rotate the filter element clockwise (same as twisting the screw) to remove it;

3. Screw the new filter element counterclockwise;

4. After the filter element is replaced, be sure to test the water, turn on the faucet and drain the water for 10 minutes to rinse, and observe whether the filter element seeps or leaks.

Although it is becoming easier and easier to replace the filter element independently, there are some details that AICKSN editors still want to remind everyone to pay attention to:

1. Before replacing the filter element, you must first confirm the size and size of the filter element. It is best to buy the original filter element of the same brand. If the length of the new filter element is not enough, you can add a rubber pad.

2. When installing the filter element, be sure to align the position of the parts and the interface first, because the bottom of the filter element is prone to offset, and pay attention to the strength when twisting the filter bottle to avoid damage to the filter bottle.

3. When replacing the filter element of the water purifier, it is best to clean and disinfect the inner wall of the machine shell, the water outlet pipeline and other components to avoid secondary pollution.

The above is the most complete knowledge about the water purifier filter element compiled by AICKSN editor. After all, the filter element is the most important functional component of the water purifier, which directly affects the purification function and effect of the water purifier. When using the water machine, you must always pay attention to the use of the filter element to avoid incomplete filtration or secondary pollution!
