Product Q&A

Q:Is your company a manufacturer or trading company?

We are a manufacturer with our own factory and cooperate with other factories using our technology. We have an 18-year background in the reverse osmosis membrane industry with independent R&D personnel and engineering, mastering core technology of high salt water purification.

Q:What is your minimum order quantity (MOQ)?

Our minimum order quantity varies by model. The minimum for household membrane is 100 units (two boxes), and the minimum for industrial membrane is five pieces. Differences also exist for OEM orders.

Q:What are the advantages of your products?

Our technical advantage lies in high desalination technology with a unique polyamide coating process. Household membranes can handle 3,000-6,000 ppm water quality, and seawater membranes can 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 are responsible for freight costs according to a reasonable quality problem 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 aim to be stronger rather than the biggest, maximizing product quality and service in the segmented high desalination market.
