How to choose mask

Cover your cough with surgical masks

If you are shopping for a mask to stop the spread of an infection to your family or colleagues, look for a surgical mask . A good quality surgical mask generally has a three-ply layer with the innermost layer used for absorbing moisture, the middle layer is a filter and outermost layer repels water. Surgical masks are made from fabric or polypropylene and should have a minimum of 95 percent bacteria filtration efficiency.

For a mask that reduces your exposure to airborne elements, look for a “respirator” such as an KN95 mask. They typically come in a contour cup design, have an adjustable nose piece and have at least two elastic straps that go around the head, one above the ears and one below.

Tip: Respirators are not designed to fit children as their faces may be too small for the respirators to fit properly. While it is not ideal, it is better for children to wear a surgical mask if protection is needed.

Disposable masks and respirators are meant for single-use and should never be shared, washed or recycled. So if your mask or respirator gets damaged, soiled or if you have trouble breathing with it on, it should be discarded and replaced with a new one.

When buying your masks and respirators, check for:

The manufacturer’s name printed on its packaging.

The filtration efficiency that you are looking for disposable masks should have a filtration efficiency of 80 percent or higher, and N95 respirators should have a filtration efficiency of 95 percent.

Unused disposable respirators are valid for about three years from the date of the manufacture—if they are not opened and are stored properly.

So when you need to stock up on masks, keep an eye out for those that suit your needs.
