1, the filtered components are different.
Water purifier: Through some chemical action or adsorption, the water purifier can remove some harmful substances such as heavy metal ions in water, as well as rust, bleaching powder and organic pollutants remaining in water, bringing you natural and tasteless drinking water.
Filter: The filter only removes some large impurities in water.
2. The advantages are different.
Water purifier: Water purifier can not only remove harmful substances, but also retain beneficial minerals needed by human body in drinking water, such as minerals and trace elements. Can meet the needs of people with different constitutions for healthy drinking water, and is safe and healthier.
Filters: Filters can filter all kinds of physical impurities in water, but the water filtered by filters cannot be directly drunk by human body.
3. Different uses
Water purifier: Water purifier can remove bacteria, impurities, toxins and heavy metals. Through filtration and adsorption in water, and the filtration function is relatively powerful, it can even filter out some harmful microorganisms, so such water is generally drunk by people.
Filter: The filter mainly filters out most harmful substances in water through the principle of activated carbon, and restores the essence of water source, but it still cannot be directly drunk in subtle places. Generally, the water filtered by the filter is used for industrial production or other commercial purposes.
4. Which is better, the water purifier or the filter?
The water purifier can filter out bacteria and heavy metals in water, and can also absorb residual chlorine, pesticides and other chemicals in water, while the filter can only filter out physical impurities in water. Therefore, the water purifier is better than the filter in purifying water quality.
5. Type of water purifier
1, filter water purifier:
This water purifier adopts filter element structure, which can be matched with different filter elements according to different needs. Its advantages are relatively low price and high filtration accuracy (including ultra-filter element). The disadvantage is that the life of the filter element is relatively short (for example, the life of PP cotton is 3-5 months, the life of activated carbon is about half a year, and the life of ultrafiltration is 1-2 years), and the water output is small, so it is only suitable for drinking.
2, pure water machine:
This kind of water purifier adopts RO reverse osmosis technology, which first appeared in the aviation industry and was developed to solve the drinking water problem of pilots. Its advantage is high effluent precision (nothing can pass through except water molecules), but its disadvantage is that the purified water is too pure and lacks trace elements beneficial to human body. An average of one cup of purified water will produce three cups of wastewater, and electricity will be used at the same time.
3, ion water machine:
Through electrolysis, water is electrolyzed into two kinds of water: acid and alkali. Alkaline water is used for drinking (because people are acidic, drinking alkaline water often can adjust the acid-base balance and promote metabolism), and acidic water is used for bathing (or sterilization). At the same time, the molecular groups of water are changed by electrolysis (water becomes a small molecular group with 6 molecular groups). This kind of water machine was first used as a medical instrument, which has a certain effect on common skin diseases. His disadvantage is that the cost is high (generally about 6000 yuan), and the pH value of water depends on the electrolytic version, which requires electricity.
4, magnetized water machine:
Advantages: through magnetization, the molecular groups of water are changed, which is more conducive to human absorption. Disadvantages: People with gastrointestinal diseases should use it with caution, because magnetized water has certain stimulation to the stomach.
5. Central water purifier:
The water purifier is installed on the main water inlet pipe at home, and all the water in the home can be purified. Its advantages are long service life (minimum 5 years) and convenient operation. At the same time, it has backwashing function, which can prolong the service life of filter material. The disadvantage is that the purification accuracy is not particularly high, and the effect is not particularly good if it is used to treat drinking water.
