Is there any third party doing air purification filters quality test?
Third party quality test is to make sure that the quality test on air purification filters is more objective and the product quality is more credible. Authoritative third parties have been invited to conduct quality tests and certificates have been obtained. You may find them on the official website. The quality certificates are strong evidence about the company's capability. They are solid foundation for the business development in domestic and foreign markets.
