Respirator w/ Filter Adaptor Mk.2\r\n\r\nA cutting-edge respirator design that seamlessly integrates with your preferred filtration material. Each standard surgical mask can be expertly cut into four efficient filter "discs", effectively multiplying its lifespan by fivefold. The inlet of the filter shroud skillfully diverts airflow at a 45-degree angle, dramatically reducing the risk of aerosol contact from the front side. The exterior surface of the filter is remarkably resilient and can be sanitized with 70% ethanol/isopropanol without compromising its hydrophobic properties. The design's optimized size and shape ensure effortless use and visual appeal.\r\n\r\nImportant User Notification: By CC BY-NC 4.0, commercial utilization of this design is strictly prohibited.
