Selecting the water filter high quality filter is the key

Should the filter element be replaced in time? Does the purified water affect the absorption of minerals by the human body... At present, the variety of water purifier products on the market is dazzling. In this issue, water quality experts from Amway, Angel, Yikou and other water purifiers are answering questions from consumers.

Question 1 should the filter should be replaced in time?

"Currently, there are different purifier structures on the market. Some use only filter cartridges, some use ultrafiltration membranes, and some use reverse osmosis technology. The volume of the filter cartridge is relatively small, only 40 cm. If it is not used for a long time, it will adsorb debris. It breeds bacteria, so the filter should be cleaned regularly, and the water filtered by the water purifier should be boiled. At the same time, the activated carbon and various filters should be replaced according to the rated water production. The water output is large, the replacement cycle is long, and the water output is small. The replacement cycle is short." Water quality experts revealed that the water purifier brand uses filter cartridges. The filter replacement cycle of each brand varies from 1 month to 5 years, but the quality is not replaced by the filter. Time to measure, "Like contact lenses, the daily throw is not necessarily better than the year, but the technology is different."

After purchasing the water purifier, there are maintenance costs every year. The more filter elements, the more expensive the maintenance. Some brand filters need to be replaced every year, and the price ranges from tens of yuan to nearly 1,000 yuan. Experts have said that there are still some water purifiers known as automatic cleaning functions, which cannot be thoroughly cleaned. Therefore, no matter what type of water purifier is selected, the filter element should be replaced in time.

Question 2 Will purified water affect health?

Many consumers believe that the water purifier will filter out the beneficial minerals in the process of purifying water. “No. Usually the minerals ingested by the human body are obtained through the food chain of plants, animals, human bodies, or plants and human bodies. The trace elements in our daily food are enough to regulate the balance of our trace elements, minerals in the water. The content is very small.” Angel water quality experts said that the water purifier is not 100% to remove all minerals, the RO reverse osmosis membrane is generally between 93% and 98%, and its filtration pore size can ensure the removal of heavy metals, bacteria, A harmful substance with a large diameter such as an organic substance allows the beneficial trace minerals to remain in the water through the filter pores and be absorbed by the human body.

“Professional technology water purifier, the filter can remove a variety of pollutants that may be harmful to health, while also retaining beneficial minerals such as calcium and magnesium in the water, and the water output rate of the activated carbon filter is 100%.” Amway Research and Development Center Expert Robert said that this will not only save water, but also protect human health.

Question 3 Is the water purifier industry standard perfect?

At present, the water purifier industry is still in the development stage, the market system is not perfect, and some small and medium-sized enterprise products are uneven. At the time of purchase, the consumer can check whether the filter core material used in the product is an international original high-quality core material, whether the product has many national technical quality standard certifications, and whether the product components have national health approvals.

It is also necessary to see whether the product's water purification process is comprehensive, the type of multi-stage filter and the actual volume of the filter element, to see if there is a guarantee of flushing the sewage outlet, hydropower safety technology, water-saving technology and water pressure connection technology. At the same time, the water quality of each water purifier is compared, the water quality is clear, the taste of the water is tasted, the hardness value of the water quality is measured, and the difference in the purified water quality in the tea cooking can also be compared.

Question 4 How to choose a quality water purifier?

Water quality experts recommend that high-quality filter elements and approvals are the focus of purchase. When consumers purchase an ideal water purifier, they must first understand the water quality and household purification requirements in the region. For example, the hardness of the water in the north and the south, the industrial pollution level of the developed coastal cities, and then consider the health and safety needs and taste of the elderly children. Determine the appropriate water purification products and solutions based on the needs.

In addition, we should try our best to buy brands with high reputation. Specialized brand-name products have been appraised by the national health and technical supervision department, which meets the national water purifier water quality standards. The quality is more reliable. Consumers should carefully identify the brand qualifications and national certification. Logo. At the same time, installation and after-sales service is also one of the key points of purchase. The water purifier is a durable consumer appliance product. The product has a long service life and maintenance support is especially important. Consumers need to understand the product's after-sales protection policy, whether there is a transparent and reliable after-sales commitment, a simple after-sales service hotline and a professional after-sales service team.
