- What is the difference between the masks with valve and those without valve? 带阀门和不带阀门的区别？
The masks with a valve have an active carbon filter and an exhalation valve. The carbon layer filters gasses such as ozone (O3), which is created from mixing sunlight with vehicle exhaust fumes and can be damaging to the lungs. It also removes more smells, which can be useful for cyclists.
The masks with valves are also convenient for spectacle-wearers, and spectacles won’t steam up with breathing.
- What is the return policy? 退货制度
Masks that are found to be defective can be returned for exchange or refund within 90 days of purchase.
