Water purifiers are entering thousands of households. It has the characteristics of fresh filtration, fresh drinking, and no secondary pollution. In addition to the cause of raw water pollution, the main reason is that people's health awareness is improving!
Regular filtered water is an overlooked yet indispensable nutrient that will make you healthier, more energetic, and live longer. "It" is an essential but often overlooked component of the human body. If you have physical discomfort, when you take in enough water, some physical health problems can be solved or alleviated, such as: asthma, allergies, high blood pressure, high cholesterol, headaches, migraines, etc.!
The water purifier is also called a water purifier or a water machine, and a filter is a small water treatment equipment for deep purification of water quality according to the requirements of water use. The water purifier we usually talk about generally refers to small filters used for household use. According to different purification principles and processes, water purifiers can be divided into two categories: water purifiers and self-cleaning water purifiers. The gradually tightening water purifier is also called the progressive water purifier. Its internal pipeline design is the same as the standard configuration mentioned above. It is composed of PP cotton, granular carbon, compressed carbon, RO reverse osmosis membrane or ultrafiltration membrane, and after Activated carbon is generally composed of 5 stages connected end to end in sequence. There is only one passage for the internal pipeline, and the dirt is deposited inside the filter element, which needs to be manually removed and cleaned regularly to ensure the normal operation of the machine. Most of the products currently on the market belong to this category. a category.
The other is a more advanced self-cleaning water purifier that has appeared since 2008. There are two channels in the machine, and a new washing water channel is added. There is a complete channel for washing water and purified water. Those who go their own way and let the water flow. When the washing water used as ordinary domestic water passes through the passage, it will flush the filter element in the machine, especially the raw water side of the membrane filter element, to achieve self-cleaning. Use the opening and closing of the washing faucet. In an instant, the wasted water at the head and tail will discharge the trapped dirt in time and quickly. This structure is designed reasonably, saving the trouble of manual disassembly and washing.
In layman's terms, the self-cleaning water purifier is equivalent to installing a garbage processor on the pipeline, and the dirt can be cleaned out at any time without staying in the machine. The traditional non-self-cleaning water purifier is equivalent to placing multiple trash cans in the room, and the dirt is usually temporarily stored in the machine, which requires regular sewage discharge, disassembly and cleaning, and frequent replacement of filter elements.
When we buy, we often don't know how to choose. Generally, the water purifier technologies we come into contact with include activated carbon filtration, ionization technology, RO reverse osmosis technology and other activated carbon filtration technologies: activated carbon is the highest quality natural adsorption material in nature. There are also many kinds of activated carbon. Granular and powder activated carbon can absorb impurities in water, and the cost is low. The disadvantage is that some unfiltered water will flow out from the gaps in the filter material. Activated carbon sticks are a safer choice, and can achieve 100% complete filtration. High-performance activated carbon sticks are fine and compact, high in efficiency, and can absorb residual chlorine, odor, VOC and other chemical substances in water.
The identification of activated carbon technology is also very simple. Pick up the filter element and shake it, and the rustling is the lower-end granular or powdered activated carbon. Advantages: The price is relatively low Disadvantages: The water filtered by activated carbon does not meet the standard of drinking water Alkaline water and weakly acidic water are separated and drained by a ceramic ion separation membrane with negative and positive electrodes. The water concentrated at the cathode is drinking alkaline water; the water concentrated at the anode is acidic water for external use.
These two properties of water are collectively referred to as ionized water. Based on this working principle, ion water machine technology is also called electrolysis ion water machine technology. Because the water purifier using this machine can produce alkaline water, some brands will claim that the water purifier using this technology has health care functions, which is misleading consumers. Advantages: Purified water can be divided into acidic water and alkaline water, which can be used for sterilization and drinking Disadvantages: The price is relatively high RO reverse osmosis technology: the main working principle of reverse osmosis technology is to exert pressure on water to make it selective The water purification effect is achieved through the reverse osmosis RO membrane. In this process, the reverse osmosis RO membrane plays the main role of filtration, which will filter out harmful substances, scale, bacteria, viruses, heavy metal ions, organic compounds and inorganic salts in the water, and only allow water molecules and mineral elements to pass through. , so as to achieve the filtering effect.
According to statistics, the filtration accuracy of this technology reaches 0.0001 micron, and the volume diameter of the virus is between 0.03-1 micron, so it has a very high filtering ability. Harmful substances that cannot pass through the reverse osmosis membrane will be discharged together with the waste water. Advantages: high purity of water purification Disadvantages: more waste water, short service life of the filter membrane Generally, if consumers choose to buy household water purifiers, RO reverse osmosis technology It can be prioritized that the purity of the water after filtration is high.
The water purifier uses tap water as raw water, and through advanced filtration technology, it removes various harmful substances in the water while retaining the physiological activity of natural water. There are many kinds of water purifiers on the market now, you can see the following points on how to choose a water purifier. Filter-type water purifier This kind of water purifier uses filter knots according to different needs, with different advantages: cheap price, relatively high filtration accuracy Disadvantages: the life of the filter element is relatively short, and the water output is small, which is more suitable for drinking. Without the backwash function, the pollutants will accumulate in the filter element. With the use of the machine, the effect of purified water quality will gradually decline.
There are many brands of water purifiers on the market now, but the quality is uneven. We should pay attention to a few issues when purchasing. Currently, water pollution in my country is mainly caused by organic matter and heavy metals. Generally speaking, most of the tap water in the south comes from surface water. We all know how serious the pollution is. In the north, most of the tap water comes from groundwater. The groundwater is a bit cleaner, but it has more minerals. A large amount of scale will be produced, and groundwater sources also have excessive levels of fluorine, arsenic, iron, and manganese.
There are two main types of water purifiers on the market: RO reverse osmosis and ultrafiltration. For the treatment of extremely small organic molecules and heavy metals, RO reverse osmosis water purifiers are the most ideal products. It can isolate more than 98% of pollutants in water, and is currently the most advanced water purification technology. Ultrafiltration water purifiers can filter sediment, rust, larger bacteria, etc. in the water, but they can't do anything about extremely small organic matter such as pesticide residues, heavy metal ions, etc. The advantage of ultrafiltration water purifiers is that they are cheap. But its filtering ability is far less than that of RO reverse osmosis. Therefore, ultrafiltration water purifiers are suitable for use in areas with good water quality, such as municipal tap water, etc. Ultrafiltration can meet daily needs. For water or groundwater treatment in rural areas with industrial pollution or poor water quality, I suggest that you buy RO reverse osmosis water purifiers.
I also have an RO water purifier installed at home. In addition to its first-class filtering effect, it can also deal with some sudden water supply incidents, such as the large-scale drinking water pollution incidents that have occurred in the past. With it, there is no need to worry about any pollution of drinking water. In terms of price, it is not recommended to buy too cheap ones. Although some brands are relatively cheap, the quality is not good enough, and the filtered water is even dirtier than the original water! For the health of children, you should choose a good water purifier.
From the appearance of this Midea water purifier, the membrane switch of the water purifier adopts a touch screen membrane switch. The touch screen membrane switch has two colors of black and gold. There are four LED lights on the touch screen membrane switch, which are respectively PP indicators. , C'UFC indicator light, RO indicator light, smart WAIFI indicator light, download the smart APP on the mobile phone, connect the water purifier, and you can control the water purifier at any time. If the light is always on, the filter element is in normal use, the white light flashes, and the filter element Life is about to expire! Therefore, it has the characteristics of abrasion resistance, waterproof, dustproof, harmful gas prevention, relatively long life and stable performance. For the neatness of the whole machine, the panel can be scrubbed, the characters will not be damaged, the colors are rich, and the newness is good!
