| The filter fitted in the Respro® Ultralight⢠Mask as standard (Cinqro⢠Sports filter) is a Hepa-type filter, perfect for sub-micron black smoke particulates and pollen (smaller than PM2.5 and less than 1 micron). The filter pack supplied with the âcomboâ kit is the Cinqro⢠Urban Filter. This filter is a combination filter made of an Dynamic Activated Charcoal Cloth (DACC) layer laminated to the Hepa-type particulate layer of the Sports filter. It provides a broader spectrum of screening which would include wood gas and carbonaceous pollution together with filtration from urban vehicle pollution. |
