   In recent years, along with the air quality, water quality and soil change, water purifier has become in many essential household appliances. But how the overall product quality of the Consumers Association today released the results of comparative test of 40 water purification products show:? Water quality samples of drinking water are in line with our requirements, but there are differences in the water quality of different types of water purifiers, heavy metals, purification efficiency difference of volatile organic and inorganic significant.

   The results show that after 28 indicators of lead, mercury, chloroform and other test, generally water processor (paragraph 22) processors and purified water (18.2 ) two samples, significant purification effect for seven indicators total hardness, total dissolved solids, iron, sulfates, chlorides, fluoride and nitrate nitrogen difference.

   wherein, the corresponding water quality and general water quality of raw water effluent processor (i.e., water) compared to values 鈥嬧€媗ittle change, but the water quality of pure water processor sample index value much smaller than the value of the raw water. Comparative test results indicate that the substance is a reverse osmosis water purification water contains fewer, more pure water.

   The test results show that most samples chloroform better purification effect. In general water quality processor section 22 samples, there are 10 products claim to have a purifying effect chloroform, chloroform samples paragraph 5 better purification effect. In a sample of 12 claims no purifying effect of, there are 6 samples chloroform better purification effect. 18, paragraph

   of purified water samples were declared to the processor with a purifying effect chloroform, paragraph 13 wherein the purification effect is better.

   test showed that pure water purifying effect on the sample processor chloride significantly better than general water quality processor samples.

   In general water quality processor section 22 samples, only one sample shall have a purifying effect claimed to chloride. After testing, the purifying effect paragraph 22 of the sample chloride are poor. 18, paragraph

   Purified water processor samples were claimed to have a chloride purifying effect. After testing, these 18 models of pure water processor chloride have good purifying effect.

   The test results show, generally water processor samples the limited ability of lead removal, the processor of pure water samples generally have effect removal of lead.

   In general water quality processor section 22 samples, there are 4Claimed to have purifying effect of lead, which has been tested and 2 of this article has a good purification, in 18 sample models do not claim to have a purifying effect of lead, the models have been tested and have a better purification effect. 18, paragraph

   of purified water samples were declared to the lead processor has a purifying effect. Testing found that 18 models of pure water processor of lead have good purifying effect.

   report that the test can be seen by the comparative test results, the water quality is generally limited processor capacity of heavy metals in the purification. If you need to remove heavy metals, usually using a special way of purification. If consumers have special needs removal of heavy metals in water, after-sale technical recommendations of the Advisory personnel, whether to meet demand by increasing filtration unit or otherwise. Pure water processor in general can effectively filter heavy metals in water.

   In addition, the results also showed that some samples purifier lack the necessary parameters and instructions. If not marked "rated total net amount of water" (water purifier filter water is the highest that can be processed), you can not know the time to replace the cartridge, continued use may have a "secondary pollution" harm to consumers of drinking water .

   reported that, by examining the description and the flag tag of 40 samples, five models found not explicitly rated total net amount of water; paragraph 2 does not expressly rated net flow; paragraph 2 samples without reverse osmosis nominal consumption power. In

   Consumers Association stressed that buy water purifier is not expensive enough, cheap on benefits. 6:00 and made consumer tips, namely: to confirm the type and purification capacity, demand to buy cost-effective products; confirmation health permits, certificates or relevant test reports; confirm the instructions for use of the product (nameplate and specification); confirm the claims of enterprise removal; confirmation method for cleaning before use; understand cost, confirm service capabilities.
