outfit them with a respirator mask

"To find out which respirators work best in emergency situations, we spoke with Nura Sadeghpour, a spokesperson for the National Institute for Occupational Safety and Health (NIOSH), the federal agency that certifies respirator masks. We also consulted Dale Schornack, a spokesperson for the California Department of Public Health; Venessa Vidovich, the supervising public health nurse at the Shasta County Health and Human Services Agency; representatives from mask manufacturers 3M and Honeywell; and John Ramey, who runs The Prepared, a site that reviews supplies for emergency preparedness.

We also consulted educational materials from NIOSH, as well as from the Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention (CDC).
If you need (or anticipate needing) to protect yourself from poor-quality air, keeping a respirator mask on hand makes sense. When outdoor air quality is compromised by particulate matter—solid and liquid debris that can be inhaled and cause health problems—staying inside as much as possible is the best thing you can do, and using HEPA filters in your home can make a big difference. But if you must go out, wearing a respirator mask that seals securely to your face and filters particulate matter can help keep you safe.

All respirators work via a series of fine screens designed to filter out airborne particles, including dust, mold, and bacteria. The same mask a person might wear on a construction site can filter out the harmful particles in wildfire smoke or the dust coming from earthquake rubble or another destructive event. The screens are not fine enough to filter out all potentially harmful gases, but on a smoky or polluted day respirators are the only way to protect yourself on the go.

People who frequently travel to places with poor air quality or pollution may also find respirator masks useful, as will those dealing with mold infestations in their homes. People with impaired lung function, due to asthma or emphysema, for example, should check with their doctor before using any respirators. Note that respirator masks are not effective for people with beards: Facial hair can prevent a mask from sealing against the skin, allowing particles to sneak in.
To check your local air quality more precisely, type your zip code into AirNow, an EPA resource that provides a national map of current fires and useful fact sheets.

As with many emergency preparedness supplies, respirators can sell out or be otherwise unattainable during times of increased demand, such as after a natural disaster. When you’re building up your stock of emergency supplies, it’s wise to include a reusable mask and replacement filters or a box of disposable masks. Most disposable respirators can work for around eight hours before you should discard them, whereas reusable masks can work indefinitely provided you replace the filters per the manufacturer’s instructions. “We recommend having a half- or full-face mask plus a few boxes of disposables,” said John Ramey of The Prepared. “That’s what I do.”

If you’re unsure whether the air around you warrants donning a respirator mask, check with your county’s department of health, where officials may update residents on evacuations or where to pick up free masks, as California’s Shasta County did during the 230,000-acre Carr Fire (PDF) in the summer of 2018. To check your local air quality more precisely, type your zip code into AirNow, an EPA resource that provides a national map of current fires and useful fact sheets.

A good rule of thumb, as California pulmonologist Robert Blount told Healthline during the 2018 wildfires: If you can see or smell smoke, it’s dangerous enough to warrant wearing a mask.
Is there a respirator mask for kids?

NIOSH does not certify any respirator masks intended for children. Although you can find masks in smaller sizes, they are still meant to best fit adult faces and may be too big on a child to form the tight seal that’s necessary to ensure protection. In addition, respirators obstruct airflow, so while they make the air safer to breathe, they also make it more difficult to breathe, which is riskier for kids than for adults. Some public health departments are also apprehensive about how masks may offer a false sense of security that leads people to spend more time in hazardous outdoor conditions than they otherwise would. This concern is especially acute when it comes to kids: Because children’s lungs are still growing, they’re especially vulnerable to wildfire smoke and ash, according to the EPA. Although it’s likely difficult and inconvenient, the far better course is to keep children inside and away from hazardous air conditions as much as possible rather than to outfit them with a respirator mask."
