Water purifiers have become a must-have product for families. Water purifiers are generally purely physical filtration. Installing water purifiers at home terminals is an effective way to ensure water quality. As consumers pay more attention to the health of drinking water, water purifiers have been in a rapid development stage for the past few years. However, the purchase of water purifiers, many people still blindly choose high price or low price as a distinction, some people think that the high price is definitely good quality, some people think that the products are all similar, the choice of low prices will not be pit, is this really true?
Water purifier purchase considerations
The purpose of installing the water purifier is to remove harmful substances from the water and ensure the safety of the water. Identify the quality of the product from the materials used in the water purifier. The water purifier is generally five-stage filtration, progressive filtration, the first few stages are pretreatment, and the core is ultrafiltration membrane or RO reverse osmosis membrane filtration. The coarse filtration adsorbs large amounts of impurities such as sand, rust, and insects through the activated carbon, and adsorbs bleaching powder, organic matter, and the like in the water through the activated carbon. Therefore, the ultra-precision ultrafiltration membrane or RO reverse osmosis membrane can be further inserted, and the water quality after filtration can reach the direct drinking.
The core membrane is the ultrafiltration membrane and the RO reverse osmosis membrane. If the selected water purifier does not have these two membranes, it is generally called coarse filtration, and the water quality after filtration is not recommended for raw drinks. And in the filtration precision of the core ultrafiltration membrane, most of the current brands are difficult to achieve the accuracy of 0.01 micron products of 0.01 micron. According to the smallest bacterial virus currently found, it is about 0.03 microns. If it can reach 0.01 micron, harmful substances can be intercepted, washed regularly, and the water quality can be safe. Since the birth of the Liss K film in the last century, it has been one of the most stable ultrafiltration membranes.
And with the continuous development of the pure water machine market, the high wastewater and small flow of RO reverse osmosis membrane has always been the pain point of the industry. Liss pioneered high-throughput low-waste membrane materials, once again breaking the industry's silence. High-throughput and low-fluid wastewater has become a hot spot in the industry, laying the foundation for the current water-saving pure water machine technology. Lisi has also become a brand pursued by consumers.
Different types of water purifiers, different prices
The water purifiers are currently purchased in the kitchen, and some are installed on the bathroom pipes leading to the toilet pipes. If it is mainly for the safety of drinking water in the kitchen, then choose the water purifier of the kitchen installation class. Such water purifiers are generally cheaper, ranging from more than 1,000 to more than 4,000. If it is a soft water machine for bathroom pipes, it is mainly used in the north and northwest regions to reduce the hardness of water. Such prices generally range from 8,000 to over 10,000. If the whole house purification system is considered, the pre-filter + full house water purifier / central water purifier installed on the main pipe is generally more than 4,000 to more than 10,000. Of course, this is also a product portfolio that looks at customer needs and choices.
