Product Q&A

Q:Is your company a manufacturer or trading company?

We are a manufacturer with our own factory and cooperation with other factories using our technology. We have an 18-year background in the RO membrane industry with independent R&D personnel and core high salt water purification technology.

Q:What is your MOQ for orders?

MOQ varies by model. The minimum for household membranes is 100 units (two boxes), and for industrial membranes, it is five pieces. OEM orders have different minimums.

Q:What are the advantages of your company and products?

Our technical advantage lies in high desalination technology with a unique polyamide coating process. Household membranes handle 3,000-6,000 ppm water quality, and seawater membranes handle 30,000-40,000 ppm, offering significant cost advantages.

Q:What is your guarantee for quality problems?

We maintain zero customer complaints on 3G and 4G products. If a quality problem occurs, we guarantee replacement and cover freight costs based on a reasonable verification process.

Q:How many employees does your company have?

HJC headquarters has more than ten people, with 142 workers in the factory and 16 office workers. We focus on being stronger rather than the biggest in the segmented high desalination market.
