The question of whether N95 masks protect against ozone has been addressed by federal health and safety authorities. According to recent information, these authorities have not approved N95 masks or any other disposable face mask for protection against ozone.
The report, which was prepared by the Colorado Sun, confirms that no official approval exists for using disposable masks to guard against ozone exposure. As a result, individuals seeking protection from ozone should look to other recommended measures.
