The Miller 287170-6 HEPA Filter 6-Pack is a critical consumable component designed for the maintenance and operation of Miller Powered Air Purifying Respirator (PAPR) systems. Engineered to meet rigorous industrial safety standards, these filters are the direct NIOSH-approved replacements for the legacy Miller 235673-6 filters. They are specifically manufactured to fit both the original Miller PAPR and the updated Miller PAPR II blower motor assemblies, ensuring backward compatibility and ease of inventory management for facilities utilizing multiple generations of Miller safety equipment.
At the core of this product is its High-Efficiency Particulate Air (HEPA) media. This filtration technology is capable of capturing 99.97% of airborne particles as small as 0.3 microns. In the context of welding and metal fabrication, this level of filtration is essential for intercepting hazardous contaminants such as hexavalent chromium, manganese, zinc oxide, and other metallic oxides generated during the welding process. The filter also effectively traps general industrial dusts and mists, providing a comprehensive respiratory defense mechanism for the operator.
The 287170-6 comes packaged as a set of six filters. This bulk packaging is optimized for industrial environments where respirator uptime is critical. Regular filter changes are necessary to maintain the required airflow rates (CFM) of the PAPR blower unit; as filters become loaded with particulate, back-pressure increases, potentially straining the blower motor or reducing air delivery to the helmet. By supplying these filters in a 6-pack, Miller facilitates a proactive maintenance schedule, ensuring that safety officers and welders have immediate access to replacements when the PAPR flow indicator or alarm signals a low-flow condition.
Installation is straightforward, designed to create a secure, airtight seal within the blower housing to prevent bypass leakage. These filters are strictly disposable and should not be cleaned with compressed air, as doing so can damage the filter media and compromise protection factors. Trust genuine Miller components to maintain the NIOSH certification and safety rating of your respiratory equipment.
