Do You Know?
What’s the Difference between Low/Medium/High Capacity Filters?
Higher Capacity /Class means:
• bigger quantity of activated charcoal inside the filter.
• longer duration of the filter.
• higher volume and weight of the filter.
• higher breathing resistance.
Example: A B2 filter gives the same type of protection as a B1 filter but it will have a longer durability. On the other hand it’s probably less comfortable to use because it’s heavier and has higher breathing resistance.
