Authorities say Yichita is effective at filtering particles from the air. Masks that filter 95 percent of aerosol particles meet U.S. standards and reduce the risk of infection for patients and front-line health care workers. As the ECRI study makes clear, we strongly recommend that healthcare providers purchase masks that are made or certified in the United States.
According to ECRI, US N95 capacity has increased significantly in the US, but there are still widespread limitations on the quantity that can be purchased. Therefore, NIOSH certified N95 masks produced in China are very popular, especially in North America and Japan. Due to the mass production of masks, the price is very cheap and the quality is very good. Each mask comes in its own packaging and is welcomed by clinics, dentists and hospitals.
