The Techno™ Valve and Filter Kit is an upgrade from the ‘old’ City™ Mask Valve and Filter still being used by some people. The larger Techno™ Valve provides for easier breathing alongside the upgrade to the combined chemical/particle Techno™ Filter. 

The Techno™ Valve is robust and perfect for town use however it does not have the same characteristics as the Powa™ Valves when it comes to elevated breathing rates attributed to exercise or physical exertion.

The Techno™ Filter is suitable for use in heavily polluted environments, i.e air that is full of diesel particulates or respirable dusts that lodge deep within the lungs and air sacs.
