GOING UNDERGROUND The problem down there is particulates, so the best mask would be either the Sportsta™ Mask, or the Ultralight™ Mask. The all round package we suggest for urban pollution whether on a bike, bus, train or walking or running, would be the Respro® Ultralight™ Mask with a Cinqro Urban Filter. The Ultralight Combo pack includes the mask (with sports filter fitted) and a pack of Cinqro Urban filters. The Cinqro Urban filters are the best filters for filtration of gases, vapours and sub-micron particulates 'The Pollution Mix'. The Ultralight™ Mask shell is made from air permeable material which is good for facial ventilation, has the Elite Powa valves for humidity control in the mask and by substituting the Cinqro Urban filter you get both submicron particle filtration together with gas and vapour filtration providing overall a broader spectrum of screening from vehicle pollution. The filter fitted into the Ultralight™ Mask as standard, the Cinqro Sports Filter, is a Hepa-Type sports filter, perfect for sub-micron filtration (smaller than PM2.5), particulates as well as dust or pollen etc. So, the Ultralight™ or the Sportsta™ is the way to go, whether as a standalone product or as a combination product.
