Respro Techno/City Anti Pollution Replacement Valves
These Respro Techno/City Anti Pollution Valves are a replacement for the original valves that came with your City™ Mask. They use medical-grade silicone rubber diaphragms and, when you exhale, allow heat, vapours and carbon dioxide to escape. They can be used in combination with any Respro® mask (except the Metro Mask).
Features
- Exhalation valves with medical-grade silicone rubber diaphragms
