A NIOSH N99 filter is the addition we recommend to ensure you’re protecting yourself in the back country. This small addition to your pocket mask, filters out 99% of airborne bacterial and viral particles, thus protecting rescuers from COVID-19. Although hands only CPR can be effective, rescue breaths are an essential part of a resuscitation attempt in drownings, suffocations and when working with youth and infant populations. This filter is our recommended addition for anyone working with youth populations, in and around water and anyone who wants to ensure that they can deliver the highest standard of care, while ensuring proper precautions are taken against COVID-19. Work and play safely in the backcountry, by guaranteeing you can provide the highest degree of resuscitative care.
