SUMMER POLLUTION High levels of air pollution during the summer can inflame the airways in your lungs and over a long period of time, will affect how well your lungs work. People with asthma are particularly affected. A FILTER FOR SUMMER RUNNING To beat the smog and keep on running, make sure to use a Hepa-Type™ sports filter for summer pollution. RESPRO® CINQRO™ MASK The Respro® Cinqro™ Mask comes fitted with a Hepa-Type™ Sports filter, which screens fine respirable, sub-micron dusts. The spare filter in the box is a combination filter (DACC™+ Hepa-Type™) for those heavy, vehicle exhaust-filled city running days. Both filters are interchangeable, making the Cinqro™ Mask suitable for use in a wider variety of environments, from inner cities to the countryside.
