Mask with carbon filter are designed to filter out at least 95% of particulates larger than 0.3 microns in diameter. The filter is made of five layers of non-woven and activated charcoal microfiber. It is easy to provide great protection against non-oil based aerosols and blocks particles from grinding, sanding, sweeping and filters out flour, pollen, metal, wood dust and more. It has aluminum strip on the outside across the bridge of the nose that can be bent for a custom fit. The nose piece is flexible enough to form a secure fit around the top of the mask. And it comes with a soft foam padding which can be incorporated on the inside across the bridge of the nose to to reduce fogging and provide all-day comfort.
Dual one-way exhalation valve prevents fogging and overheating exceptionally well. Thanks to its neoprene construction, it is more Well-ventilated, breathable and quick drying. It is especially useful for those who need to wear the mask for hours at a time. It is better to replace the filter every 25-30 hours if the mask is used extensively. The mask is also designed well because it uses both a loop system which sits comfortably behind the ears to keep it firmly in place, but also has velcro strapping behind the head, so there is no need to consistently readjust the mask or have it slip. The durable design ensure a comfortable and firm fit and prevents dust and other contaminants from penetrating the mask.
