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.

Replace filters, keep your RZM3 mask
RZM3 uses snap-in F3 filters. When a filter needs changing, replace the compatible filter while keeping a serviceable mask shell. That can cost less than replacing the whole mask, and lets you keep a fresh set ready for your next job.
Choose the filter that matches your RZM3 size, follow the product instructions for replacement, and use the mask only for suitable particulate tasks. RZM3 is not for gases, vapors, chemical fumes, or work requiring an approved respirator.

Three ways to wear your RZM3
The included strap configuration gives you three wearing options: a neck strap, dual head straps, or ear loops. Choose the setup that works with your eyewear and headwear, then adjust the mask and nose piece for a secure, comfortable fit before you start work.

Designed to reduce glasses fogging
Fogged safety glasses interrupt your focus. RZM3's adjustable nose piece, nose foam, and exhalation-valve design work together to limit warm breath rising toward your lenses. Adjust the mask with your own eyewear and check the fit. If fogging appears, reseat the nose piece and straps to improve the seal.
100% Satisfaction Guarantee
Breathe through the work
Choose the compatible RZM3 F3 filter for suitable particulate work. The replaceable-filter design lets you change a used filter when needed and keep the serviceable mask shell for the next task.
Adjust the fit to your day
Soft materials and three strap options help you choose a setup for your face, eyewear, and headwear. Adjust the nose piece and straps, then check the fit before use.
A system you can keep using
RZM3 pairs a reusable shell with replaceable filters. Keep compatible replacements on hand so a spent filter does not mean buying an entirely new mask.

Filter options for your RZM3
RZM3 F3 replacement filters are available with an active-carbon layer for odor considerations during suitable particulate work. Match the filter to your mask size and task, and replace it according to the product instructions. An active-carbon layer does not make RZM3 suitable for gases, vapors, chemical fumes, or work requiring an approved respirator.

How long do RZ filters last?
The life expectancy of your RZ Filter depends on many variables, such as; particulate exposure density, particulate exposure duration, and user breathing rate.
Ultimately, filter life depends on your environment. Replace your filter when breathing becomes noticeably harder, the filter looks dirty, or after heavy-dust days.
What kinds of particles do RZ Masks help protect against?
RZ Masks are designed to help reduce exposure to airborne particulates like dust, pollen, smoke, and other jobsite or everyday nuisance particles. Different models/filters have different performance levels, so check the product’s certification or filter spec for exact use-cases.
