7502 Half Mask

3M is similar to the same model 7502 half mask; the main body is made of rubber and plastic, which is soft, environmentally friendly and highly comfortable, while ensuring good tightness, good oil resistance and not easy to age. The downward exhalation valve discharges heat and moisture when exhaling, reducing the accumulation of heat and moisture in the mask and making breathing smoother. The elastic headband can be adjusted according to the face shape, and the adjustable head frame provides a more comfortable wearing method. There are two wearing methods: standard and hanging. The buckle assembly design makes the filter box easy to disassemble and maintain and clean. A variety of filter elements can be selected, and it is easy to maintain. The mask is valid for five years. The mask body and filter cotton cover can be washed and reused after air drying.
