For cycling/walking in the urban/city environment, we recommend the Techno™ mask where pollution is high and full of diesel particulates. The Techno™ filter in the Techno™ mask is the Sports filter and the City™ filter combined giving the user both sub-micron particle filtration with gas and vapour filtration.

The Techno™ filter has sub-micron filtration capability. What this means is that it is able to trap particles less than one micron in size which is more than capable of the removal of 2.5 micron Particulate Material (PM2.5).
Typically particulate pollution in the cities appears to be in the 2.5 micron size range and above. Particles smaller than this are known as respirable dusts, which can lodge deep within the lungs and air sacs. This is the more dangerous type of particle pollution as chemicals from vehicle exhaust emissions are carried to the blood barrier by means of respirable particulates. Hence the need for a Hepa-Type™ sub micron particle filter.

The DACC™ activated charcoal layer within the Techno™ filter has excellent adsorption properties when it comes to SO2 and NO2 uptakes. With this capability and its capability of filtering VOC’s it is the best filter available in our range for dealing with the broad spectrum of pollutants commonly found in major cities across the globe.
