How long can a filter be used before it must be removed and discarded?
Please follow NIOSH N95 guidelines or consult your company’s safety officer. If the filter reaches maximum load and breathing becomes labored, immediately leave the contaminated environment and replace the filter with a new filter. If the filter material is physically damaged or soiled, the filter must be discarded and replaced.
Our mask does such a great job at physically protecting the filter. It may look great at the end of the day, but it’s not suitable for multi-day use. Please discard any filters inside the mask at the end of the day and clean the mask before putting it away.
Always follow the guidelines provided by your company’s safety officer and for additional information, visit CDC publication on filter usage provided by the National Protective Technology Laboratory (NPPTL).
Can the filter be washed or reused?
