This Respro Powa/Sportsa Valves-Duplicate is no longer available although you may find similar or newer versions below:
In order to have good breathability in a mask especially when undergoing exercise or other activities involving physical exertion, it is essential that the mask breathes freely and does not create either a pressure drop or back pressure within the mask.
Heat, carbon dioxide and water vapour, three components of exhaled breath, need to be exhausted from the mask in readiness for the next breath of inhaled air. If this process of evacuation fails or is impeded, then the mask may become uncomfortable with poor airflow and may result in the wearer not using the mask.
We therefore believe that exhalation valves are an essential component which allows the mask to perform well under the conditions described above.
The valves in Respro® masks are designed to reduce or eradicate any of the above effects and are available in accessory packs, allowing the user to tailor a product specifically to their own needs.

Respro product designer Harry Cole had "in your face" experience of exhaust fumes and city smog as a London cycle courier and this is still a significant and growing problem. In 1990, Respro launched the City mask, the first cyclists pollution mask and it is still in demand today. Over the last decade, awareness of air pollution has grown and now cyclists can choose from a wider range of styles and filters to accomodate more individual needs. Respro masks are supplied with replaceable filters and exhalation valves to keep the inside of the mask well ventilated.
