The secret in the cartridge: is the water you drink really clean?

Behind the seemingly clear water flow, there may be hidden threats to the health of the invisible crisis.

Filter cartridge: the last line of defense for drinking water safety

1. The Shocking Truth of Filtration Data

According to experimental data, a high-quality water purifier can intercept about 2,600 milligrams of rust, 900 milligrams of organics, and 8,500 milligrams of sediment per year. These pollutants, if accumulated for a long period of time, may cause problems such as increased burden on the liver and kidneys, and developmental delays in children. Research by the Chinese Center for Disease Control and Prevention (CDC) shows that for every 10 micrograms/liter increase in blood lead levels in children in areas with excessive heavy metals, the IQ drops by an average of 2.5 points.

2. Intuitive interpretation of the technical principles

-Activated carbon: like a sponge adsorbs residual chlorine and odors, but poor quality carbon may release pollutants.

- RO reverse osmosis membrane: pore size of only 0.0001 microns, can intercept viruses and heavy metals, but need to be protected with pre-filtration

Ultra-filtration membrane: retain minerals while filtering bacteria, suitable for better water quality areas

Second, the three major hidden dangers of poor-quality filter

1. Secondary pollution is more dangerous

According to a local police seizure of counterfeit cartridge cases show that poor-quality filler (such as industrial carbon, stone) not only filtration failure, but also the release of plasticizers and other harmful substances. A community in Guangxi has been due to poor quality filter cartridges lead to water colony number exceeded 40 times, triggering collective diarrhea.

2. Health costs are difficult to bear

Long-term use of coal carbon filter families, the detection rate of benzopyrene (a class of carcinogens) in the water is three times the normal value. Beijing Water Bureau experiments have confirmed that the lead content of the water out of the overdue cartridge may exceed the tap water.

3. The traps behind the economic accounts

A consumer to buy a low-priced water purifier cheap, two years to change the core cost more than the price of the machine. In contrast, the average annual cost of the regular brand cartridge about 40,000 U.S. dollars, equivalent to a daily investment of 0.14 U.S. dollars for the health of the whole family.

Third, the scientific purchase of the five golden rules

1. Recognize the "three certificates and a report"

View the water-related products health permit approvals (such as the number of health water), water quality test reports and 3C certification, alert to the "permanent exemption from core replacement" and other false propaganda. 2.

2. Material is more important than quantity

-Activated carbon selected coconut shell material (iodine value ≥ 1000mg / g)

- RO membrane recognized Dow, Toray and other international manufacturers of film

-Composite cartridge needs to have a clear layered structure illustration.

3. Adaptation of water quality is the most critical

-RO reverse osmosis (scale removal) is preferred for hard water in the north.

-For soft water in the south, a combination of ultrafiltration and activated carbon is preferred.

Older neighborhoods are recommended to install a pre-filter.

4. Intelligent monitoring is more worrying

Choose the model with cartridge life reminder function (such as APP reminder, indicator light), to avoid replacement by feeling. A family in Hangzhou found that the actual life of the activated carbon cartridge was 40% shorter than the nominal value through intelligent monitoring.

5. After-sales service is a guarantee

Check whether the brand provides door-to-door core replacement service, and be wary of online shopping platform "three-free" filter. Regular companies usually have a national joint warranty network, and provide water quality review commitment.

Guardian of health, from the change of the right cartridge to start

Drinking water safety is not a multiple choice question, but a must-answer question. Choose a qualified water purifier, regular replacement of high-quality cartridges, like for the body to hire a professional escort. After all, even more advanced medical means, can not compare with the advance construction of this visible health line of defense.
