Review on 🎭 Irisvito Dust Face Masks: Reusable Activated Carbon Filter Outdoor Sports Mask with Breathing Valve - Fashion 2020 Colorful Masks for Ventilation & Protection by Chef Buntiloy

The lid is really well made but the dimensions are TERRIBLE. The filter falls apart after 10 minutes of use. The pre-punched holes are not made correctly. Makes the filter "stick" to your face and traps CO2. The mask folds too often. The ear straps are stretched. Much needed improvement: The mask needs a flexible shell to hold the shape of the mask. Filters should be plug-in , not fixed.The CO2 outlets require strong plastic construction.When this mask is used for training, it is too fragile to withstand the brunt.
