Choose what kind of water purifier, mainly based on the living location of the water quality, personal drinking water needs, and treatment effect to decide. Currently on the market a wide variety of water purifiers, the following for you to analyze the advantages and disadvantages of a variety of water purifiers
1, cartridge-type water purifier:
This water purifier uses a cartridge structure, according to the different needs of the different cartridges can be paired with the advantages of the cheaper price, the filtration accuracy is relatively high (contains a super-filter cartridge). The disadvantage is that the life of the cartridge is relatively short (for example, the life of the PP cotton in 3-5 months, the life of the activated carbon in about half a year, the life of the ultra-filtration 1-2 years), the water output is small, and is only suitable for drinking.
2, water purifier:
This water purifier uses RO reverse osmosis technology, first appeared in the aviation industry, is to solve the problem of drinking water for the airmen and research and development, the advantages of high precision water (in addition to the water molecules, any substance can not), the disadvantage is that the purified water is too pure, the lack of all the human body is beneficial to the microelements, an average of a cup of pure water, to produce 3 cups of waste water, and must use electricity. The main reason for this is the fact that it is not possible to use electricity.
3, ionized water machine:
Through electrolysis, the water electrolysis for acid and alkaline two kinds of water, alkaline water for drinking (because the human body is an acidic structure, often drink alkaline water, can regulate the acid-base balance, promote metabolism), acidic water used for bathing (or used to sterilize and disinfect), and at the same time, through electrolysis, change the molecular group of the water (water will change to 6 molecules of small molecular groups). (changing water into small molecular clusters of 6 molecules). This type of water machine was first used as a medical device, for common skin diseases have a certain degree of efficacy. His disadvantage is the high cost (ordinary about 6 thousand), while the pH value of the water also depends on the electrolysis version, need to use electricity.
4, magnetized water machine:
Advantages: through magnetization, change the molecular group of water, more conducive to human absorption. Disadvantages: people with gastrointestinal disorders should be used with caution, because the magnetized water has a certain gastrointestinal stimulation.
5, centralized water purifier:
Water purifier installed in the home of the total water intake pipe, so that all the water at home are purified, the advantages of a long life of the filter media (the shortest is also 5 years), easy to operate, and at the same time with the function of backwashing can extend the life of the filter media. The disadvantage is that the purification precision is not particularly high, if used to deal with drinking water, the effect is not particularly good
Based on the above comparison, the final conclusion is that there is no single water purifier that can deal with all the water in the family (a normal family should have three kinds of water, one is the original water, used to wash the car, mop the floor, wash rags, a kind of purified acidic water, used for washing, a kind of purified alkaline water, a kind of water, a kind of water, a kind of water, a kind of water. The most scientific way to deal with the problem is to install a set of water purification combination, a whole house water purification, used to purify the whole house water (including bath water), and then in the whole house water purification based on the installation of a kitchen water purifier in the kitchen (control of microorganisms in the water to achieve the standard of drinking water) so that it is more scientific. At the same time, it is recommended that if you have the conditions, the home toilet water pipe and the main water pipe separate single go, because the toilet water is not necessary to purify, if the purification, on the contrary, will affect the life of the filter media of the water purifier (toilet water accounted for 60% of the water in the family)
