The water purifier is not properly purchased, and it is carefully turned into a "stain" water heater.
With the improvement of social living standards, water purifiers have also entered the ordinary people's families. As you can see, inferior water purifiers can cause pollution to drinking water and affect human health. So how do you buy a quality and practical water purifier?
1. Check the health approval documents
Whether domestic or imported water purifiers, it is necessary to check whether there are sanitary approvals issued by the health department at or above the provincial level, whether the approval documents are within the validity period (valid for 4 years), whether the contents of the approval documents and their attachments are related to the actual water purification of the products. The process and materials are identical.
2, see the water purification process, function and effluent quality
The water purification process is PP water + activated carbon water purifier can partially remove organic matter; the water quality of the water purifier with hollow fiber ultrafiltration membrane meets the requirements of the general water purifier effluent water quality in the sanitary code; the water purifier with nanofiltration membrane effluent The water quality meets the requirements of “drinking water quality standardâ€; the water quality of the water purifier with reverse osmosis membrane meets the requirements of the reverse osmosis water purifier in the Ministry of Health, and the pollutants are almost completely removed.
3, look at the quality of the materials used
The prices of the same materials and components of different materials vary greatly, for example: whether the plastic is all new or recycled; the activated carbon is coconut shell charcoal, shell charcoal or cheap coal charcoal; stainless steel is 316L, 304 or 302. The quality and performance of the material not only determines the quality and performance of the water purifier, but also determines the quality of the effluent water and the service life of the water purifier or its components. General material materials will be reflected in the manual.
4, see the manufacturing, assembly process and appearance
The water purifiers produced by the formal enterprises are beautiful in appearance, rigorous in assembly, bright in appearance and smooth in surface; while the products of small workshops are gray in appearance, rough in surface, rusted, cracked, loosely assembled, and even leaking.
5, look at the manufacturer and product brand
The small factory is small in scale, the factory and equipment are simple, no technical strength, just buy various parts for assembly, and some even the assembly factory does not, go to other factories for OEM production, product quality can not be controlled and guaranteed. Therefore, we should try our best to buy the products of the brand produced by the formal enterprise.
In addition, the CDC experts should remind the general public that even if a water purifier with a qualified filter element is purchased, the effect of the water purifier will be greatly reduced or even caused by the water filter because the filter or filter membrane is not cleaned for a long time. Secondary pollution. It is recommended that the public must periodically clean and replace the filter element or filter according to the requirements of the product manual.
