An N95 mask is a popularly-used, short- acronym name for an approved N95 particulate filter respirator, which is a particulate filtration facepiece respirator that satisfies the strict requirements of the United States National Institute for Occupational Safety and Health (NIOSH). Since the early 1980s, the NIOSH has set up and directed systematic research studies and reviews to ensure that N95s satisfy all the safety needs of the industry. In the past decade, many changes have been made to N95s, specifically those that affect assembly line production. However, one of the most significant was the inclusion of a battery isolator device, which ensures that your battery does not suffer from the damage caused by galvanic reactions.
