ML00994 - Miller LPR-100 Half Mask Respirator with Nuisance OV Relief - Small/Medium

Advanced Respiratory Protection for Industrial Welding

The Miller LPR-100 Half Mask Respirator (Small/Medium), identified by SKU ML00994, is a precision-engineered safety device designed to address the specific respiratory challenges faced by professional welders. This unit provides P100-rated filtration, certifying it to remove 99.97% of airborne particulates, including hazardous solid dust particles, metal fumes, and mists. It is particularly effective against toxic compounds generated during welding, such as hexavalent chromium from stainless steel, zinc oxide from galvanized steel, as well as manganese, aluminum, nickel, iron oxide, copper, cadmium, lead, and beryllium fumes.

Nuisance Level Organic Vapor Relief

Distinguishing itself from standard particulate respirators, this model incorporates Nuisance Level Organic Vapor (OV) Relief. The replaceable filters feature a specialized activated carbon layer designed to adsorb organic vapors and odors that exist below OSHA Permissible Exposure Limits (PELs). This feature significantly enhances user comfort in environments where welding odors are prevalent, reducing distraction and improving the overall work experience without requiring heavy-duty gas cartridges.

Ergonomic and Low-Profile Engineering

The LPR-100 is defined by its extreme low-profile architecture, specifically developed to integrate seamlessly with personal protective equipment (PPE). It fits comfortably underneath most welding helmets, including the Miller Weld-Mask™ 2, ensuring that the user's field of vision remains unobstructed. The mask's ergonomic design minimizes dead air space, preventing the accumulation of carbon dioxide. Coupled with a large non-return exhaust valve, the system efficiently expels exhaled air, reducing heat buildup and breathing resistance to minimize user fatigue during prolonged shifts.

Medical-Grade Material Construction

Safety and biocompatibility are paramount in the construction of the LPR-100. The mask body is manufactured from medical-grade materials that are completely free of latex and silicone, rendering it non-allergenic and odor-free. A four-point head strap system with an integrated comfort cushion ensures a secure, customized fit that remains stable during active work. The exclusive pleated filter design maximizes surface area for extended filter life, while a wrap-around spark guard protects the filter media from direct contact with sparks and spatter.
