With the improvement of living standards, many consumers are increasingly concerned about water quality safety. As a device that can filter and purify water quality, water purifiers have become indispensable equipment for some families.
Water purifiers appeared relatively early, but the penetration rate in China is not high, and the recognition in the minds of consumers is average. The main reason is that the water purifier market is chaotic, and inferior products are shoddy, which brings many problems to consumers.
How to choose a water purifier and what should I pay attention to?
1. Brand
Big brands of water purifiers have better performance in terms of performance, quality, technology and after-sales, and have a high reputation and sales volume.
If you don't know how to choose, choose a big brand of water purifier, and it won't be bad to have the State Quality Supervision Bureau to check for you.
Domestic brands mainly include Haier, Xiaomi, Midea, Yikaide, Angel, Qinyuan, etc., which are cost-effective. Foreign brands mainly include Smith (United States), Eco (United States), 3M (United States), Scher (Switzerland), etc., the price is a bit expensive, if the budget is sufficient, you can consider.
Second, the filter element
At present, the water purifier is mainly equipped with two types of filter elements, one is a composite filter element, and the other is an RO reverse osmosis filter element.
The composite filter element is made of several materials, such as PP cotton, activated carbon, carbon fiber, etc., which can filter rust, sediment, large particles of organic matter, etc. According to the water situation, it needs to be replaced once every 1-2 years, and the price is generally within 300 yuan.
The RO reverse osmosis filter element has high filtration accuracy, which can reach 0.0001 microns, and the water produced can be directly drinkable, which belongs to pure water. According to the water situation, it needs to be replaced once every 4-6 years, and the price is generally around 1,000 yuan.
3. Water yield
RO reverse osmosis water purifier, in the process of use, there will be wastewater, which is expressed by the index of water purification water production rate%.
The water yield of the first grade purification water is ≥65%, which means that 1 liter of water will produce 0.65 liters of pure water and 0.35 liters of wastewater.
The water yield of the second-level water purification is ≥55%, and the water yield of the third-level water purification is ≥45%.
The higher the percentage of water yield, the less wastewater is produced. At present, regular RO reverse osmosis water purifiers are all first-class water purification water yields, and some models can be several percentages higher.
RO reverse osmosis water purifier is mainly for drinking water, so the amount of wastewater produced in a year is limited, and the price is less than 100 yuan.
Fourth, function
Some models of water purifiers have a dual water outlet mode, one side is used for domestic water, and the other side is used for direct drinking water. The double waterway design avoids cross-contamination of pipelines and makes direct drinking water healthier.
Some high-end water purifiers also have intelligent functions, which can check water quality, water consumption, filter life reminders, upgrade machines and other functions to escort safe water use.
Fifth, after-sales
Water purifier manufacturers have a perfect after-sales service system, which can better provide consumers with professional technical support and maintenance services to ensure that there are no worries in the process of use.
