N95 Professional Multi-Purpose Valved Respirator

Milwaukee 48-73-4012 N95 Valved Respirator – NIOSH-Certified Protection with Cooling Valve

The Milwaukee 48-73-4012 is a NIOSH-approved N95 valved respirator engineered to provide effective respiratory protection against airborne non-oil-based particulates. Designed for use in construction, remodeling, and material processing environments, it incorporates a proprietary exhalation valve that reduces internal heat by up to 10°F for improved comfort in high-exertion tasks.

Product Features

• NIOSH N95 Certification: Filters at least 95% of airborne non-oil particulates as defined by NIOSH standards.
• Cooling Valve: Integrated vent helps lower internal mask temperature, reducing heat buildup during extended wear.
• Flexible Nose Bridge: Moldable nosepiece ensures a secure seal across varying face profiles.
• Adjustable Dual Straps: Soft latex-free straps provide even pressure distribution and maintain mask position.
• Low-Profile Design: Allows for compatibility with other PPE such as safety eyewear and hearing protection.

Use Guidance

Ensure a tight facial seal by adjusting both straps and forming the nose bridge for optimal fit. Respirators should be inspected for damage before use and discarded after exposure to high particulate loads or moisture. Not intended for use in environments containing oil aerosols or gases/vapors without additional protection.

Contractor Notes

Designed for jobsite demands, this respirator offers consistent filtration performance while minimizing heat and moisture buildup in the mask cavity. Its form factor supports extended wear in confined or ventilated work zones where particulate exposure is elevated.
