SA00820 - Miller P100/OV Replacement Filters for LPR-100 OV Respirator (Pair)

High-Efficiency Filtration for Hazardous Environments

The Miller SA00820 P100/OV Replacement Filters are engineered to provide superior respiratory protection for professional welders and industrial workers. Designed exclusively for the Miller LPR-100 OV Half Mask Respirator, these filters offer a dual-action defense mechanism against airborne contaminants. The primary P100 filtration layer is NIOSH certified to remove 99.97% of airborne particulates, including hazardous metal fumes such as hexavalent chromium, zinc, manganese, lead, and cadmium. This makes them an essential safety component for welding on stainless steel, galvanized steel, and other alloyed metals.

Organic Vapor Relief Technology

Beyond standard particulate filtration, the SA00820 cartridges feature an integrated layer of activated carbon. This specialized media is designed to absorb organic vapors and odors, providing relief from "nuisance level" vapors that do not exceed OSHA Permissible Exposure Limits (PELs). This feature is particularly beneficial in mixed-use environments where workers may be exposed to paint fumes, solvents, or oily metal residues during weldment cleaning. The pore structure of the activated carbon is optimized for maximum absorption efficiency, ensuring a cleaner, more comfortable breathing experience.

Advanced Design and Construction

Miller utilizes an exclusive pleated filter design in these cartridges. By increasing the surface area of the filter media, the pleated structure allows for greater contaminant holding capacity, effectively extending the service life of the filter. Furthermore, this design significantly reduces breathing resistance, reducing user fatigue during long shifts. The filters are constructed from medical-grade materials that are odor-free, non-allergenic, latex-free, and silicone-free, accommodating a wide range of user sensitivities. The patented filter media is also hydrophobic, maximizing efficiency in both humid and non-humid conditions.

Critical Safety Compliance

These filters are a critical component in maintaining compliance with occupational safety standards. They are strongly resistant to oil aerosols and provide robust protection in environments with heavy fume generation. It is important to note that these filters are specifically keyed for the LPR-100 OV mask and provide the necessary protection for applications involving both particulate matter and organic vapors.
