How many days is the filter on the M50 mask good for in an uncontaminated area?

• A. 30 days
• B. 60 days
• C. 90 days
• D. 120 days

Answer: (B)

In a clean, uncontaminated environment, the M50 mask filter is good for about 60 days of use. The filter media is designed to maintain filtration performance for roughly two months when it isn’t loaded with contaminants. Once you move into a contaminated area, the filter saturates and degrades more quickly, so its effective life is shorter. If you notice increased breathing resistance, an odor or taste, or any signs the filter is saturated, replace it promptly. Always follow the manufacturer’s guidance and your unit’s procedures for filter replacement.
