3M 6001 Organic Filter (pack of 2):
The 3M 6001 organic filter is used for masks with two filter layers. The mask should be worn before entering an environment with hazardous chemicals. If you smell chemical odors or feel difficulty breathing, you should replace the filter with a new one and keep the mask to save costs. In cases where the mask is deformed and no longer retains its original shape or the strap is stretched.
