YUNDA H&H Teach is one of the earliest Chinese manufacturers to simultaneously obtain NSF, WQA, and IAPMO certifications. With strong capabilities in certification management, product quality, and R&D, YUNDA products—including refrigerator filters, coffee machine filters, pitcher filters, pool & spa filters, and other filtration solutions—have built a solid presence in major markets across Europe and North America.

As our business continues to expand, the variety and number of international certifications we hold have also been steadily increasing. Our current product portfolio covers almost all residential and outdoor water filtration applications, including reverse osmosis systems, water dispensers, under-sink and countertop water filters, pool cleaning robots, shower filters, whole-house filtration systems, and RV water filtration systems. Relevant certifications include globally recognized standards such as NSF, WQA, IAMPO, TÜV, WaterMark, CE, FCC, CB, and ETL.

Each year, YUNDA invests significant resources in laboratory testing and certification for newly developed products. As a result, we obtain hundreds of new certified products annually, ensuring continuous compliance with evolving international standards.

Today, nearly all YUNDA products are certified under relevant global requirements. In addition to mainstream certifications, we also develop products with region-specific approvals tailored to different market regulations and customer needs.

With extensive experience in international certification processes, YUNDA supports customers in leveraging existing certifications and accelerating additional approval processes, helping them bring products to market faster and more efficiently.

In addition, YUNDA operates its own independent laboratory, which allows us to conduct rigorous testing throughout product development and production to ensure consistent quality, safety, and compliance.
