It has a five-layer filter consisting of 2 x 30 gsm melt blown, non-woven filters. 2 x PM 2.5 filters and 1 x activated charcoal filter.
The Nano Wave mask is designed to be extremely comfortable to wear with a contour fit and is not painful on the ears. It allows for comfortable breathing and easier talking. The one-way valve helps reduce the unwanted build-up of carbon dioxide and the increase in body temperature leading to extreme discomfort. This comfort factor is critical to the protection of the wearer who, if experiencing discomfort, as is the case with most “cloth” masks available today may feel the need to pull the mask off or fiddle with it, creating a far more concerning risk in the process. Full exposure and face touching are serious risks and large part of what mask wearing is trying to avoid.
The nose clip assists with a contour fit and may reduce the fogging up of glasses significantly, adding to the overall comfort while wearing the mask and reducing the need to face touch or fiddle with the mask.
The valve is one directional for easier exhaling purposes. Exhaling through the valve does significantly reduce the flow of breath being exhaled. This simply means that the air is not “expelled” or forced through the valve at a high volume therefore impacting the distance that the breathed-out air will travel once leaving the valve. What is more significant however, is that the valve is designed to close when a sudden high volume of air is forced through such as when the mask wearer coughs or sneezes. In most cases a symptomatic individual would not be allowed to enter public places after screening.
