Product details, compatibility and care
RZM3 is a reusable particulate dust mask for suitable tasks. Its adjustable nose clip, three wearing options and replaceable filters let you set up the mask for your own use. Check the fit with your safety glasses and confirm the protection required for your task before wearing it.
A reusable mask with replaceable filters
Keep and clean the shell according to its care instructions. Replace the matching filters as directed for your conditions of use. Filters are not washable. The current listed package includes one RZM3 mask, two F3 filters and a storage bag; check the selected option and order details before purchase.
Choose how to wear it
- Head strap: an option for active tasks and compatible headgear.
- Neck loop: an option for taking the mask on and off between tasks.
- Ear loops: another wearing option when appropriate for the task.
Position the adjustable nose clip and follow the RZM3 fitting instructions. Fit, comfort and eyewear fogging vary by person, glasses and conditions; no mask can guarantee clear eyewear or a suitable fit for every wearer.
Check the task and the filter
RZM3 is a particulate mask, not a NIOSH-approved respirator. Do not use it for gases, vapors, finishing fumes, oxygen-deficient atmospheres or work requiring a NIOSH-approved respirator. An active-carbon layer for nuisance odors does not make it suitable for chemical-vapor protection. Employers and safety personnel should determine workplace requirements.
Use only filters compatible with your exact RZM3 model and size. Inspect and replace filters according to the product instructions and exposure conditions. See RZM3 F3 replacement filters or check filter compatibility.
What is listed in the package
- One RZM3 mask with adjustable three-strap system
- Two F3 replacement filters
- One storage bag
For work that requires a certified respirator, review the applicable product approval and your workplace's requirements before selecting equipment. Review RZ product evidence and status or ask RZ a product question.

Ultimately, filter life depends on your environment. Replace your filter when breathing becomes noticeably harder, the filter looks dirty, or after heavy-dust days.
