FAQ – North Defender N99 Filters
Q1: What level of protection do the North Defender N99 Filters provide?
The North Defender N99 Filters deliver 99.97% filtration efficiency against non-oil-based particulates, offering near-HEPA-level protection. These filters are NIOSH-approved, ensuring compliance with 42 CFR Part 84 standards. They effectively protect against dusts, fumes, and mists in industrial and occupational settings where respiratory safety is critical.
Q2: What respirators are compatible with North Defender N99 Filters?
These filters are compatible with the North 5400, 5500, 7600, 7700, RU8500, and RU6500 Series respirators. Their flat, low-profile design allows for easy installation and comfortable wear, whether used alone as N99 filters or as prefilters with approved cartridges (excluding the Defender cartridge).
Q3: Can these filters be used in multiple industries?
Yes. The North Defender N99 Filters are designed for multi-industry applications, making them ideal for agriculture, fire protection, law enforcement, medical, pharmaceutical, and transportation sectors. Their versatility ensures reliable protection in any environment where non-oil particulate exposure may occur.
Q4: What makes N99 filters different from N95 or P100 filters?
N99 filters offer higher efficiency than N95 (99% vs. 95%) and are comparable in performance to P100 filters for non-oil particulates. However, unlike P100 filters, N99 filters are not oil-resistant, which makes them ideal for environments where oil aerosols are not present but high filtration performance is required.
Q5: Are North Defender N99 Filters OSHA compliant?
Yes. When paired with approved North respirators, these filters meet OSHA 29 CFR 1910.134 requirements for respiratory protection programs. They help employers maintain regulatory compliance while providing workers with dependable protection against harmful airborne contaminants.
Q6: How often should the N99 filters be replaced?
Filter replacement depends on environmental conditions and exposure levels. Replace filters immediately if breathing resistance increases, odors become noticeable, or visible damage occurs. Following a routine inspection schedule ensures continued protection and compliance with NIOSH and OSHA standards.
