The type of water purifier
The first step in our purchase of water purifiers is of course to start from the type of water purifier, the more common on the market is ultrafiltration water purifier and reverse osmosis water purifier, their difference is reflected in their filter element, that is, water purifier technology.
Ultrafiltration water purifier uses ultrafiltration membrane, which can filter out harmful substances such as bacteria and viruses, but it cannot filter heavy metals very well, so the water it filters out is not directly drinkable, that is, it must be boiled to drink.
The filter element of the reverse osmosis countertop water filter dispenser will use the RO reverse osmosis membrane, the pore size of this membrane is very small, almost all harmful substances in the water can be filtered out, including the heavy metal ions that the ultrafiltration water purifier cannot filter, the RO reverse osmosis water purifier can also be filtered out well, of course, at the same time, the reverse osmosis water purifier will also filter out the mineral ions beneficial to the human body, so it is necessary to drink the direct drinking water filtered out by the RO osmosis water purifier for a long time, and pay attention to the supplement of minerals in other diets.
Parameters of the water purifier
(1) Rated water purification: Rated water purification indicates the total water purification of the water purifier, the higher the value, the more durable the filter element of the water purifier, and the replacement frequency of the later filter element is relatively low, so it is recommended that you can choose a product with high rated water purification at the same price.
(2) Wastewater ratio: The wastewater ratio is generally only available in RO permeable water purifiers, because such water purifiers will produce wastewater, which means the ratio of the water filtered out and the wastewater produced when the machine works, the higher the value, the better, like 2:1, 3:1 The ratio of wastewater to the top is still very good.
