The following standards. Consumers can use it as a reference when purchasing.

First, the output rate of clean water should be high.

The reverse osmosis membrane will discharge wastewater in the process of purifying water. Usually, the ratio of purified water to wastewater in the market will reach 1:3, that is, we need to consume 4L of raw water to obtain 1L of purified water. Although it guarantees our health, it runs counter to the concept of green health and environmental protection. This is the "pain point" of reverse osmosis water purifier.

Second, does the enterprise have the strength of self-research and development?

Before buying a water purifier, you should also understand the enterprise. Some enterprises, driven by some interests, only look at the immediate interests and randomly find some small workshops to form brand water purifiers. A good water purifier brand will have its own R&D team, and the R&D team will have its own core technology, which is irreplaceable by other enterprises. We can go to official website to check whether they have obtained some patent research and development, and check the authenticity of the patents. Judging the scientific research ability of enterprises from the details and understanding the development of enterprise product culture are also very helpful for choosing their favorite water purifiers.

Third, put an end to the secondary pollution of the water storage bucket.

The early products of RO reverse osmosis water purifier will be equipped with pressure barrels to realize instant water discharge. Due to the slow passing rate of RO membrane, it is difficult to meet the consumer's demand for water output, so the water storage bucket is used in early products. The benefits are obvious. When we turn on the tap, the purified water in the water storage pressure tank will flow out at a high speed, and users will not have bad experiences such as long waiting time because of the small water flow. However, due to the weak acidity of pure water, the water storage bucket has become a hotbed for bacteria to breed, and the phenomenon of bacteria exceeding the standard frequently occurs, and the secondary pollution of the water storage bucket is a headache.
