Disposable respirators have received increased attention recently with the spread of the H1N1 influenza virus, although they have long been used for other purposes, including occupational safety. N95 refers to the National Institute for Occupational Safety and Health (NIOSH) rating which establishes a mask that meets certain minimum standards for particulate transfer.
The N95 respirator is designed to filter up to 95% of airborne particles 0.3 microns or larger that can enter the user's nose and mouth directly. To get more information regarding disposable respirators, you can simply visit this https://www.planethalohealth.com/.

These masks can also be worn by people suffering from infectious diseases to prevent particles from escaping from the user's nose and mouth and harming others.
N95 masks can be purchased with valveless ones for easier breathing. Optimal protection is achieved when the respirator fits snugly on the face and covers the nose and mouth without leaving exposed areas around the edges.
The respirator must be properly attached to the user and not covered by facial hair or jewelry. A poorly fitted respirator has a greater potential for airborne particles to enter through gaps in the edges of the mask, providing less protection against inhalation or particle dispersion than a properly fitted respirator.
Respirators are widely used for workplace safety and are especially widely used in industrial and health facilities. Masks used in the workplace must be NIOSH approved, which means they meet the minimum standards set by the National Institute for Safety and Health at Work.
