What does a p100 filter protect against?
Respirator filters are rated according to how much particulate matter they can reliably block. A P100 rating is the highest for personal respiratory protection. As long as your mask fits properly a P100 filter will block 99.9% of particles .3 microns or larger.
Any filters used for protection in atmospheres with asbestos need to be rated P100. Also called HEPA filters, the P100 is a NIOSH rating. NIOSH is the National Institute of Occupational Safety and Health. The P100 respirator filters block at least 99.97% of airborne particles and are strongly resistant to oil.
- Wear an appropriate respirator. Ordinary dust masks are not effective in preventing the inhalation of asbestos fibres and dust. You should wear either a half-face filter respirator fitted with a class P1 or P2 filter cartridge, or a class P1 or P2 disposable respirator appropriate for asbestos.
- Simple dust masks do not provide sufficient protection against asbestos fibers/dust. This is one reason that homeowners should not undertake asbestos removal on their own; in order to be fully protected from asbestos dust, a special respirator equipped with an appropriate HEPA filter is generally required.
- Hard hat sizes can seem a bit mysterious. To measure for your hat size, place a soft cloth tape measure around the widest part of your head (this is usually just above the eyebrows). Pull the tape measure snug, but not tight. Convert inches to hat size using the sizing chart below.
One of the most common respirators used in health care facilities is the type N95 disposable respirator. These used to be called dust/fume/mist (DFM) masks that were certified under a previous standard. N95 filters belong to a group of air purifying particulate filters.
- HEPA respirators (High Efficiency Particle Absorbing*) are the respirators that the health care field, including EMS, formerly used for respiratory protection. They are directly replaced by the N100 mask, however for EMS the N95 mask is appropriate for protection from airborne communicable disease.

- Face masks are the perfect skin care treatment to help you with your skin care concerns. The right face mask can help hydrate skin, remove excess oils and help improve the appearance of your pores. They're also an excellent way to help pull out impurities.
