Frequently asked questions
Find clear answers about this product, from choosing it to putting it to use.
Will it fit a CM-6M or CM-8M?
Both masks use the standard Rd 40 × 1/7″ NATO connection specified for this filter. Compatibility alone does not determine whether the filter is appropriate for a particular hazard.
Does the 20-year shelf life mean 20 years of use?
No. It applies to factory-sealed storage under the specified conditions. After use begins, service life depends on exposure and use conditions.
Can this filter be cleaned or regenerated?
No. Do not wash it, use compressed air on it or try to regenerate the filtration media.
Is a mask included?
No. This listing is for filter cartridges in the selected pack quantity. A compatible respirator is sold separately.
