There are various filter types: particle, gas (e.g. ABEK) or combination filters. Depending on where you will be using them, you can protect yourself against multiple hazardous substances all at the same time. A colour-coding enables you to instantly recognise the filter type.

Filter Designation- N IOSH filter series. Alpha numerical rating followed by filter efficiency level (example, N95, N99, N100, R95, P95, P99, P100) the product.

Used with the manufacturer’s user instructions, NIOSH approval labels can help users understand the respirator, its protections, cautions and limitations, and approved configuration

The three categories of resistance to filter efficiency degradation are labeled N, R, and P. The class of filter will be clearly marked on the filter, filter package, or respirator box. For example, a filter marked N95 would mean an N-series filter that is at least 95% efficient.

Filter assembly for Low Profile P100 Particulate Filter (99.97% minimum filter efficiency) for all particulates. Filter Assembly includes 5 pair 75FFP100 and 1 pair N750035 adaptors for use …

This page provides information charts for North & 3M respirator cartridges and filters. These reference guides will help you chose what type of respirator cartridge or filter you need per situation.

Dec 2, 2024 · Learn how to navigate the respirator filter rating system by understanding the letter classifications and numerical ratings associated with it.

Filtering facepieces are disposable particulate APRs in which the entire facepiece serves as a filter. Though not elastomeric, they must be tight-fitting with a proper seal. As non-powered particulate APRs, they get the TC-84A NIOSH designation. Nuisance Dust Masks.

There are seven classes of filters for NIOSH-approved filtering facepiece respirators available at this time. Ninety-five percent is the minimal level of filtration that will be approved by NIOSH. The N, R, and P designations refer to the filter’s oil resistance as described below.
