A Smoke Mask is like an insurance policy. From our experience, since the PSM is not an instant-use product, often salesmen are needed to persuade their clients and inform them about the merits of the product.

Try to contact your clients face to face. Clients are usually more inclined to buy the smoke mask after knowing the importance of the PSM for their family and staffs.
