The Respro® City™ anti-pollution mask offers screening from the inhalation of nuisance dusts and odours associated with vehicle exhaust emissions. The City™ mask has a contoured design ensuring the mask 'seals' comfortably and is manufactured from hypo-allergenic Neoprene. The filter in the City™ mask has been specifically developed for filtering a wide variety of nuisance dusts and odours commonly found in most major cities. With two essential Techno™ exhalation valves to allow unwanted heat, carbon dioxide and water vapour out it is an excellent means of screening yourself against urban pollution.
