Pocket is way too big for PM 2.5 filter
Mask is nice and comfy, but pocket for filter is way too big  and not standardized for PM 2.5 filters.<br />As you wear it, the filter will easily fall down under your chin and not protect you as it supposed to.<br />From all masks I have this one is most comfy but it provides the least amount of protection.
