Our Advantage

Quality Assurance

Our proprietary Thin-wall PP melt-blown technology enables the thickness of PP melt-blown filter element to be less than 3mm, while still maintaining exceptional mechanical strength. These filter elements can be used as a replacement for the plastic or metal cores in composite filters, or as standalone filtration elements. This technological breakthrough allows for greater flexibility in customization and significantly reduces production costs.

Our independently developed ACF technology product – the “WT-Super Filter Cartridge” – can effectively block bacteria and viruses. While maintaining its core features of outstanding hydrophilicity, low pressure drop, high flow rate, long lifespan, and high chlorine removal efficiency, it also achieves a bacterial filtration efficiency of over 99.9999%. These filter cartridges are highly suitable for drinking water purification, industrial water treatment and purification, laboratory equipment, medical devices, life sciences, and bio-medicine applications.
