Product Q&A
Q:Is your company a manufacturer or trading company?
A:
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 core technology in high salt water purification.
Q:What is your minimum order quantity (MOQ)?
A:
MOQ varies by model. For household membranes, the minimum is 200 units (two boxes). For industrial membranes, the minimum is five pieces. OEM orders may have different requirements.
Q:What are the advantages of your products?
A:
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, while seawater membranes handle 30,000-40,000 ppm, offering significant cost advantages.
Q:What is your quality guarantee policy?
A:
We maintain zero customer complaints on 3G and 4G products. If a quality problem occurs, we guarantee replacement and cover freight costs according to a reasonable verification process.
Q:How many employees does your company have?
A:
Our headquarters has more than ten people, with 200 workers in the factory and 46 office workers. We focus on being stronger rather than just bigger in the segmented high desalination market.
