If your local tap water or drinking water quality is poor, or there is secondary pollution, buying a water purifier and installing it will definitely be good for human health.
First of all, you should know the functional characteristics of various brands and models of water purifiers in detail. Any water purifier has advantages and disadvantages. Know the water quality of your local tap water, and then buy it according to your eating and living habits. What suits you is the best.
At present, there are many kinds of water purifiers of various brands and models, including multi-filter, single-core ultrafiltration, ultrafiltration machine that can produce water without electricity, reverse osmosis water purifier that can only be used with electricity, multi-outlet, pure water outlet, pure water outlet and so on. Pure water can be drunk directly, but it has no nutritional value, just to replenish water. Clean water needs to be boiled before drinking, which is especially suitable for cooking and washing food in the kitchen. In addition, the reverse osmosis water purifier will also produce wastewater, especially in winter, the wastewater rate is as high as about 70%, and the reverse osmosis water purifier filters out harmful substances and beneficial substances in the water.
The service life of multiple filter elements also varies greatly. For example, the service life of PP cotton filter is only 3-6 months, activated carbon filter is generally 6- 12 months, and ultrafiltration or reverse osmosis filter is generally about 24 months. If it is too much trouble to change the filter element on schedule, then buy a water purifier with long life and no need to change the filter element frequently. There is no need to buy a water purifier if the local water quality is good. If the local water quality is too poor and there is a problem with the quality of drinking water, you can consider buying a reverse osmosis water purifier, also known as a water purifier. Now manufacturers have also introduced water purifiers with multiple outlets, including purified water outlets for direct drinking and purified water outlets suitable for boiling water and cooking water.
There is also the choice of brand products as far as possible, to understand the prices and replacement methods of various filter elements, and whether there is after-sales service. This way, even if it is to save costs, it is also convenient to buy it online and replace it yourself. As for small brands, there is no need to consider them. After all, after-sales service cannot be guaranteed.
In addition, it is best to buy a front filter element when installing the water purifier to prolong the service life of the filter element of the water purifier.
Users who have bought a water purifier must change the filter element regularly according to the local tap water quality and water consumption. If the filter element is not replaced for a long time, the filter element of the water purifier will become a dirt collector, which is harmful to human health.
