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. Haiana has 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 the minimum order quantity (MOQ)?

The minimum order quantity varies by model. For household membranes, the minimum is 100 (two boxes). For industrial membranes, the minimum is five pieces. OEM orders may have different requirements.

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 the warranty and quality guarantee?

All products are covered by a 12-month warranty. 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:What is the operating pressure for the ULP series?

The ULP (Ultra low pressure) series membrane operates at 2/3 of the pressure of conventional low-pressure membranes, achieving high permeate flow and rejection rates suitable for water with salt content below 2000ppm.
