It's so easy to put filters in the valves -- and some masks with valves even come with filters that fit in the valves.We’re in the Del Sur area of San Diego and rarely see others wearing any type of masks when they are out walking or socializing in the green space / parks. Hopefully the valve masks you see have the filters in place.
