The recent Swine flu epidemic that hit us has led many people to take preventive measures that can shield them from infectious particles and thereby elude them from the disease. Then there was a buzz about the word for N95 as a 3 M respirator which was approved as a surgical mask by the Food and Drug Administration (FDA) and accredited by the National Institute for Occupational Safety and Health (NIOSH) with the capacity to remove up to 95 percent of the airborne particles.

A device which protects the wearer from inhaling harmful fumes, gases, vapors and dust is called a mask of the respirator. Its generally categorized as an air purifying respirator into two types, which moves the polluted air into a filtering medium and the air services respirator, which has an alternative fresh air source in it. The simplest and most one time respirator masks are known as mask.Service Line Direct is NCH Corporation’s protective equipment and repair service division. Customers will consider a variety of items for the protection supply that cover workers from head to toe. Source hard hats, hearing aid, and leading manufacturers’ safety glasses which are fashionable, comfortable, and compliant. They are called so because they have the capacity to avoid inhalation of 95 percent of the airborne particles. Respirators 3 M are also among the common ones, as one of the oldest respirator mask manufacturers produces them. To be more precise about what mask is, NIOSH describes the term as referring to a filter class under the Respiratory Protection Approval Regulation (42 CFR 84: section 84 of chapter 42 of the Code of Federal Regulations). They are at this time filtering respirator mask in all nine classes and 95 per cent is NIOSH approved minimum filtration level; viz. , N99, N100 (Not oil resistant); R95, R99, R100 (Slightly oil resistant); P95, P99, P100 (Strongly oil resistant);
The word 95, 99, 100 refers to 95% respectively, 99%, 99.7% filtration. All respirator masks are typically licensed by the NIOSH and have been labelled with the following: the name of the manufacturer, the part number (P / R / N), the filter safety (e.g. , R99) and the emblem of the NIOSH. And some may also have the NIOSH approval number as an additional distinguishing marking. You can test those approved models on NIOSH. Generally, this kind of filter remove the particles by using certain waxes, resins, and plastics as coatings on the filter material to attract particles with an electrostatic charge that holds them on the surface of the filter material or by using gravity which allows the particles to settle in the filter material.
