Half-Face Respirator Filter Massa purple 46 mm SB1166

The Half-Face Respirator Filter Massa purple 46 mm SB1166 is a replacement filter designed for half-face masks that accept 46 mm threaded connections. It provides filtration for particulate matter and, depending on the mask and filter type, can assist in reducing exposure to certain gases and vapors. The compact, screw-in design allows straightforward mounting and replacement without tools, making it suitable for environments where respiratory protection must be restored quickly and reliably.

Advantages

This filter offers a standardized 46 mm threaded connection for compatibility with a wide range of half-face respirators. Its compact form factor and color coding help with quick identification and inventory control. The screw-in mounting ensures a secure fit and simple replacement, while construction from durable materials supports repeated handling during filter changes.

Suitable for

• Industrial workshops and manufacturing where particulate filtration is required
• Construction sites during demolition, cutting, or sanding tasks
• DIY home improvement projects involving dust, paint mist, or solvent use (when combined with compatible cartridges)
• Maintenance and repair work in facilities with airborne particulates

Key specifications

• Connection type: 46 mm threaded screw-in
• Form factor: half-face respirator replacement filter
• Color: purple (for visual identification)
• Intended use: particulate filtration and, depending on mate respirator and cartridge, gas/vapor reduction
• Mounting: tool-free screw connection to compatible mask

How to use

Ensure the half-face mask is compatible with 46 mm threaded filters before installation. Remove the protective cap if present and align the filter threads with the mask connector. Screw the filter clockwise until hand-tight to ensure a secure seal; avoid over-tightening. Replace the filter according to manufacturer guidance or when breathing resistance increases, visible damage occurs, or exposure limits are reached. Store unused filters in a clean, dry place away from contaminants and strong chemicals.

Usage recommendations

Use this filter only with compatible Massa or other masks rated for 46 mm threaded filters and follow the respirator manufacturer's instructions for correct sealing and cartridge/filter combinations. Select the correct filter type for the hazard (particulate vs gas/vapor) and replace filters regularly to maintain protection. Conduct a user seal check after installation and adhere to workplace respiratory protection protocols.
