Gill™ Mask respirator has created the most user-friendly reusable respirator mask currently available in the market. We have modernised the design to ensure an efficient, high-protection, comfortable fit that provides long-lasting durability and requires less maintenance. With proper care, your Gill™ Mask can be reused again and again for up to two years. Gill™ Mask can be used with pre-cut Gill™ Filters or any filter material of your choice cut to fit the cartridge door.
