Guangzhou Yuanzhuang Filter Co., Ltd
Innovation driven professional development in the field of environmental filtration
Guangzhou Yuanzhuang Filter Co., Ltd., located at the intersection of the Liuxi River Ecological Corridor and National Highway 105 in Guangzhou, is a technology-based private enterprise deeply involved in the entire industry chain of environmental protection filter cartridges. Since its establishment, the company has always adhered to the business philosophy of "building the foundation with technology and shaping the future with quality", focusing on the research and development of core components in areas such as air purification and industrial filtration. It has now become an important participant and innovation leader in the technical standards of China's environmental filter industry.

Anchor environmental protection needs and lay out a green industrial chain
Faced with the increasingly strict global environmental regulations and the demand for industrial upgrading, Yuanzhuang Filter has precisely entered the high value-added track, building a full category filter matrix covering three major fields: automobile exhaust purification, industrial dust treatment, and building ventilation systems. Its product line includes cutting-edge categories such as nanofiber composite filters, high-temperature resistant ceramic filters, and intelligent self-cleaning filters. Through the dual certification system of ISO 9001 and IATF 16949, it provides customized filtration solutions for world-class brands and automotive host customers. Relying on a 100000 square meter intelligent production base along the Liuxi River and a convenient logistics network on National Highway 105, the company has achieved an annual production capacity of over 10 million filter cartridges, radiating to Southeast Asia, Europe, and America markets.

Building a technological foundation and forging professional competitiveness
The company is guided by the strategy of "technology penetrating the market", investing 6% of its annual revenue in research and development innovation, forming a professional team, and through deep cooperation between industry, academia, and research, overcoming 12 industry pain points such as low wind resistance and high dust holding technology, electrostatic electrostatic polarization and long-lasting antibacterial technology. It has obtained more than 20 invention technology patents, and its unique "gradient density laminating technology" has increased the service life of filter cartridges by 30%, reduced energy consumption by 15%, and technical parameters meet the EU EN 779:2012 standard.

Innovation driven, defining a new paradigm for the industry

The company has launched a revolutionary "Oxygen Health" series of filters, which deeply integrates the function of generating negative oxygen ions into the air purification system through innovative oxygen generating material technology. This product uses natural mineral composite nanomaterials to continuously release negative oxygen ion concentrations of 1200-2000/cm ³ during the air filtration process (meeting forest level air quality standards), breaking through the limitations of traditional filters that only intercept pollutants and achieving a dual upgrade of active purification and health benefits.
Core technology: The filter material not only intercepts PM2.5 and decomposes formaldehyde, but also stimulates the ionization of air water molecules to produce ecological level negative oxygen ion groups. It has been tested and certified by the Guangzhou Microbial Testing Center and applied to high-end residential buildings, medical cleanrooms, and new energy vehicle cabins, helping consumers enjoy a "forest oxygen bar" level breathing experience in urban environments and redefining new standards for healthy air purification.
