Key Features: Designed to be used with our Element & 3D reusable face coverings,This 5-layer filter adds additional protection to our face covering,Non-woven inner and outer layers prevent larger dust particles from passing through and provide ,structure and support for the finer filtration layers,Polypropylene melt-blown layers prevent smaller particles from passing through the filter, down to a size of approximately 3 microns,The activated carbon is a highly microporous filtration layer which absorbs smaller gaseous impurities via chemical adsorption,Pack of 10 filter inserts.
The Respro Techno filter is suitable for use in heavily polluted environments, ie, air that is full of diesel particulates and respirable dusts that lodge deep within the lungs and air sacs. It is a combination of the Sports filter and the City filter giving you both sub-micron particle filtration with gas and vapour filtration. What this means is that the filter is able to trap particles less than one micron in size.
