The Honeywell North® 7580P100 Particulate Filter is a high-efficiency, low-profile P100 filter disc engineered to deliver exceptional respiratory protection against all airborne particulate contaminants across hazardous aerospace MRO, welding, chemical manufacturing, and heavy industrial operations. Featuring dual N-Series threaded connectors, the 7580P100 provides a minimum filtration efficiency of 99.97% against both oil-based and non-oil-based particulate aerosols, fine composite dusts, toxic metal fumes, and airborne micro-particles. Its compact, lightweight pancake design minimizes breathing resistance and fits smoothly under welding helmets, face shields, and grinding visors without obstructing line of sight.

Approved Specifications & Regulatory Conformance:

The Honeywell North 7580P100 filter disc complies with strict occupational safety and health standards:

• NIOSH 42 CFR 84 Approval: Fully certified under NIOSH standards for P100 particulate protection when properly attached to Honeywell North half or full facepiece respirators.
• OSHA Assigned Protection Factor (APF): APF = 10 when used with half masks; APF = 50 when paired with full facepieces under OSHA 1910.134 protocols.
• Toxic Metal & Asbestos Protection: Approved for exposure to toxic dusts including lead, asbestos, cadmium, arsenic, and hexavalent chromium.

Key Features & Performance Benefits

• Ultra-High 99.97% Filtration Efficiency: Traps toxic solid and liquid aerosols, including oil mists, fiberglass, silica, and heavy metal fumes down to sub-micron levels.
• Compact Low-Profile Design: Fits comfortably under welding hoods, grinding shields, and protective eyewear without interfering with the operator’s field of view.
• Low Breathing Resistance: Engineered pleated media matrix allows high airflow rates, reducing user fatigue during physically demanding MRO tasks.
• Direct Thread-On N-Series Connection: Screws on tightly to eliminate accidental filter detachment and prevent seal bypass during active work.
• Spark & Moisture Protection: Encapsulated housing shields inner filter media from liquid splash, grinding sparks, and humidity.

Typical Applications

• Aerospace Welding & Metal Fabrication: Protects against toxic metal fumes (hexavalent chromium, lead, manganese) during TIG, MIG, and stick welding on airframe alloys.
• Composite Maintenance & Sanding: Ideal for filtering fine carbon fiber, fiberglass, and epoxy dust generated during composite skin and radome repairs.
• Environmental Remediation & Paint Removal: Used for hazardous lead paint abatement, asbestos handling, and toxic particulate cleanup in industrial facilities.
