1, brand awareness: consumers must know the importance of product quality when buying kitchen water purifiers. The manufacturer of kitchen water purifier must obtain the hygiene license from the health supervision department at a higher level, and be appraised by the technical supervision department, which conforms to the national Quality Standard for Drinking Water.
2, cost-effective products: if the kitchen water purifier has different structures, the water purification effect is also different. Generally speaking, the structure of kitchen water purifier with primary filtration is relatively simple, with activated carbon as the main component and limited filtration capacity. It can only be used for coarse filtration, and the filtered water is best heated and boiled before drinking.
Multi-stage filtering kitchen water purifier. This kind of kitchen water purifier has two stages of coarse filtration and a group of fine filtration. The fine filtration mostly adopts hollow fiber filter element, and the filtered water can be directly drunk.
3. According to the choice of water quality: the hardness of water quality is different in different regions. The content of calcium and magnesium ions in high hardness water in northern China and limestone areas in southern China is high, which is easy to scale. You should choose a kitchen water purifier with advanced filtration and ion exchange resin filter.
If the water contains chlorine, odor and organic matter, you can buy a kitchen water purifier with more activated carbon. Because activated carbon has a strong adsorption effect on residual chlorine and odor in water, it has obvious removal effect on organic matter.
