North by Honeywell Pre-filters: Respiratory Protection Against Particles (N95 and R95)

North by Honeywell pre-filters are essential accessories designed to integrate with North line cartridges, providing a critical layer of protection against suspended particles that gas and vapor cartridges do not filter on their own.

Filtration Capabilities

• N95 Pre-filters: Have a minimum filtration efficiency of 95% against non-oil-containing particles. They are effective against dust, smoke, soot, wood, talcum powder, silica, lead, paint aerosols, as well as bacteria, viruses, and other microorganisms.
• R95 Pre-filters: Are oil-resistant, designed to filter suspended particles containing oils, such as carbon volatiles and spray paints, in addition to including the filtering capabilities of N95 models.

Compatibility and Operational Use

• Compatible Systems: They are compatible with North brand reusable half-mask and full-face respirators.
• Mounting Requirements: For installation, these filters must be accompanied by a cartridge and use a filter retainer to keep them in position, preventing movement or detachment.
• Maintenance: The retainer facilitates changing the pre-filters without needing to remove the cartridges. They should be replaced whenever they are dirty, damaged, or when breathing difficulty occurs through them.

Regulations and Safety

These products comply with the quality and safety standards established by NIOSH, the federal agency responsible for regulating respiratory protection equipment. The N95 nomenclature follows OSHA guidelines for specific protection against non-oil-based particles.
