Naroo Mask F5 Filtering/Fogging For All Seasons/Dust Block/Bicycle Riding

Easy-to-replace interchangeable filtering mask
Cover your nose and help keep your breath from going up to your eyes.
The inner filter is fine on the average, but if you have a short length of the corona, you can cut the upper part with scissors.
The product must be hand-washed in lukewarm water to prevent deformation and damage of the mask.
Please remove the external filter before washing.
