At KOWA, quality is our top priority, and we have established a quality management system based on ISO 9001:2015. This system sets production standards, ensuring every employee is dedicated to producing flawless FFUs and HEPA Filters. "Professionalism, Quality, Service, Responsibility" drives our operations, laying the foundation for excellence in every product.

Our company adheres to ISO 9001:2015 standards and continuously improves our quality management system. This commitment significantly benefits FFUs and HEPA Filters. From incoming inspections to nonconforming product control, each step ensures our processes and products meet specifications and customer expectations, ensuring their performance and reliability.

Following the "Inspection Management Procedure," we conduct rigorous incoming inspections, confirming items and verifying FFUs and HEPA Filters against requirements. This step ensures that product raw materials meet the highest standards, eliminating potential defects and guaranteeing successful acceptance.

Our in-process inspections closely monitor each production stage, eliminating variables that may cause defects and maintaining stable and consistent quality in FFUs and HEPA Filters. We use third-party calibrated instruments to test the quality and performance of each product, providing test reports that meet customer specifications. This ensures each FFU operates safely in compliance with industrial standards, and each HEPA filter achieves the required filtration efficiency. We value customer usage requirements and strive to exceed expectations, making KOWA a market leader and the most reliable product supplier in customers' operational environments.

Through our shipping / packaging inspections, we ensure that the packaging of each FFU and HEPA Filter protects the product from any potential damage during transportation. We meticulously check each product label to ensure compliance with customer specifications and presentation methods, allowing customers to quickly identify products with the same appearance but different specifications, saving time and ensuring a smooth usage and installation process.

Through warehousing inspections, we ensure that each FFU and HEPA Filter is stored in a warehouse environment that meets specifications before shipping, avoiding product damage caused by stacking and movement in the warehouse. We conduct detailed inspections of box labels, ensuring customers can quickly identify the contents of the box upon receipt, making product acceptance and categorization more efficient and saving customers a significant amount of time.

In incoming inspections, production inspections, and shipping processes, if any nonconforming products are found that do not meet the requirements, they are marked, returned, or stored in the warehouse. This ensures that defective products do not re-enter the production process or get misused, making production smoother and more effectively guaranteeing product quality, speeding up customer product delivery times.

Through improvement and preventive measures, we continuously improve our quality management system, addressing issues encountered in each process. This allows FFUs and HEPA Filters to undergo more efficient quality control and inspections from production to shipping. Through improvement and preventive measures, we ensure that all products are delivered to customers more quickly and meet customer quality requirements more efficiently.
