Therefore, in the use of household membranes, according to market feedback, it can be applied to 3,000-6,000 ppm water quality. Seawater membrane can be applied in the environment of 30,000-40,000ppm, and the cost advantage is very obvious.
Q: if quality problem,what is your guarantee terms?
A: At present, we maintain zero customer complaints on 3G and 4G products. Please note that the first item of our company's values: Do not let customers count one copper coin.
