Disposable Respirators and Dust Masks Protect Workers from Inhalation of Dust and Debris in Workshops, Demolition Jobs and more.
Disposable respirators and dust masks are constructed for comfortable and dependable use during sanding, grinding, sweeping, demolition or low level gaseous operations. Available filter classes are N95, N99, N100, P95, P100, and R95. Resistance capabilities include Aerosols Free of Oil, Chemicals/Pandemic, Fine Dust, Oil Aerosols, Non-Oil Based Particles, Oil Particulates, Pollen, Dust, and non-toxic particles. – See the bottom of the page for more detailed information.
Respiratory Filters come in a variety of ratings that relate to how the respirator performs (how much it filters) and what environment type it is designed to be used in. When choosing a respirator it's important to understand that as the letter rating and number rating increase, breathing fatigue will increase. While you certainly don't want to choose a rating that is too low, you don't necessarily always want to pick a P100 filter for every application - particularly if you're just looking for a simple dust mask to do home improvement work. Typically, an end user will find an N95 respirator cooler, and easier to breath through than a P99 or P95 dust mask.
Respirator Rating Letter Class
N - Not oil resistant
R - Resistant to oil
P - Oil Proof
Respirator Rating Number Class
95 - Removes 95% of all particles that are at least 0.3 microns in diameter
99 - Removes 99% of particles that are at least 0.3 microns in diameter
100 - Removes 99.97% of all particles that are 0.3 microns in diameter or larger. HE or HEPA quality filter.
Respirator Ratings & Considerations
Quite simply, a respirator with a rating of P100, has been tested to be proof against oil, and tested to filter 99.97% of all particles 0.3 microns in diameter or larger. In the chart below you can see various examples of the size (in microns) of various substances for comparison.
