Late at night when you unscrew the faucet to receive water, do you notice the tiny particles of precipitation at the bottom of the cup? Early in the morning boiling tap water surface floating thin white film, these details are silent: water quality crisis has penetrated the daily life of every family. Last year, the Shanghai Municipal Center for Disease Control and Prevention issued a “White Paper on Drinking Water Safety for Residents”, showing that 67% of the households have secondary water supply pollution problems, the old district water pipeline network corrosion rate of 82%. When the water factory standard water flow through dozens of kilometers of pipeline arrived at home, may have carried rust, bacteria and even lead elements.

The essence of water purifier is precise interception
On the market from $100 to $1500 water purifiers are emphasized in the “purification”, but the filtration accuracy is the core code. A laboratory dismantling comparison found that the low-priced models use PP cotton + activated carbon primary filtration combination, the diameter of less than 0.1 micron virus helpless. The real effective RO reverse osmosis membrane, filter pore size of only 0.0001 microns, equivalent to one-fifty-thousandth of a hair, can intercept including heavy metals, antibiotic residues, including 137 kinds of harmful substances. Beijing Water Quality Monitoring Center engineer Wang Lei reminded: “When shopping to recognize the NSF certification mark, which is the world's most stringent certification system for water treatment products.”

The hidden pitfalls of cartridge life
“Three years free core replacement” advertising slogan is full of temptation, but hidden mysteries. A well-known brand of water purifier flow decay curve shows that when the cumulative water production reached 2000 liters, the filtration effect has dropped 40%. More alarming is the composite cartridge bundled sales set - seems to integrate a variety of functions, in fact, the different life of the mandatory bundling of the filter material, resulting in some of the filter material early retirement. It is recommended to choose the modular design of the cartridge system, each cartridge independent replacement, annual maintenance costs can be reduced by more than 35%.

The cognitive revolution of water quality testing
TDS pen can only reflect the total amount of dissolved solids in the water, but can not detect the more dangerous organic pollutants. Comparative experiments by the Chinese Academy of Environmental Sciences showed that a community TDS value of only 58ppm (better than the national standard), but the gas chromatograph detected phthalate plasticizers. Real professional home water quality test kit should contain residual chlorine reagent, heavy metal test paper, petri dish three-piece set, it is recommended that every quarter to do a three-dimensional water quality physical examination.

Smart choice of installation scenarios
Under-kitchen water purifier is not a universal solution. Duplex houses should consider the water pressure attenuation problem, when the vertical height exceeds 5 meters, the ordinary 50G flux model water production speed will drop by 60%. Families with infants and young children, it is recommended to choose a desktop water purifier with UV sterilization. A typical case of user feedback is worthy of vigilance: the installer for the convenience of the waste water pipe directly into the sewer, three months after the cabinet appeared unknown plaque, the nutrients in the wastewater tested for microorganisms provide a breeding ground.

In the defense of water purifier selection, more important than technical parameters is life insight. Newlyweds should reserve space for upgrading the needs of mothers and babies, allergic families need to focus on the dechlorination function, and families with pets should guard against the risk of hair clogging. Remember, the real suitable water purifier is the one that can quietly integrate into the rhythm of family life, and continue to guard the health of the invisible guardian in the day-to-day use. When one day you suddenly find that the kettle is no longer scaling, brewing tea soup extra bright, this is technology to give life the most gentle response.
