The working principle of an mask filtering particles is to use different interception means of particles of different styles, such as inertial impaction, interception, diffusion, plus electrostatic attraction.

2. Kind of Face Masks:
2-1. Distinction by shape: Masks will be divided into three kinds: flat type, folding type and cup shape based on the shape. Flat-type masks are easy to sling, but have poor adhesion; folding masks are easy to place; cup-shaped breathing space is actually large, but not convenient to hold.

2-2. Classification by sporting style:

(1) Head-mounted: suitable for workshop workers who wear for long periods, which is troublesome for you to wear.

(2) Ear-worn variety: easy to wear, ideal for frequent putting on in addition to taking off.

(3) Neck-worn variety: S-hook and some soft material connectors are used to convert the ear straps suitable neck-band type suitable for long-term wear, which is easier for workshop workers wearing hard hats or protective clothing.

2-3. Classification through materials used:

(1) Gauze Confront Masks: There are even now some workshops that work with gauze masks, but the GB1908 4-2003 standards they follow conform to lower requirements and don't meet the standards associated with GB2626-2019. It can solely protect large particles connected with dust.

(2) Non-woven Skin Masks: Most disposable protective masks are non-woven masks, which are mainly determined by physical filtration supplemented by simply electrostatic adsorption.

(3) Silk cotton Face Masks: The cotton face mask only includes a warming effect without filtering the little particles such as PM2. FIVE.

(4) Paper Face Masks: suitable for food, beauty along with industries, with good air flow permeability, easy to work with and comfortable, etc. The actual paper used follows GB / T 22927-2008 standard.

2-4.Classification by scope associated with application:

(1) Medical markers: There are three kinds in China: medical common masks, medical surgical markers, and medical protective goggles.

(2) Particulate protective goggles: Industrial use complies using GB 2626-2019 standard, particular labor protection equipment basic safety mark certification (LA certification), within 2015 from mandatory qualification to voluntary certification. If its used for anti-fog and also haze, it needs to apply the insert type, that must meet the GB / T 32610-2016 normal. Civil use complies using GB / T 32610-2016 standard.

(3) Warm cloth markers: Warm masks, suitable regarding winter wear, only ought to meet the relevant benchmarks of fabrics.

(4) Alternative special industries: such since chemical industry.

2-5. In line with protection level (See the examples below chart):

Different countries and different industries have formulated different standards, which are divided in different protection levels as outlined by different particle filtration efficiency. At present, the major standards of Chinese deal with masks include:

1. GIGABITE / T 32610-2016 《Daily Sterile Face Mask Technical Specifications》

ONLY TWO. GB 2626-2006 or GB 2626-2019《Respiratory Protective Equipment, Self-priming Sieve Anti-particulate Respirator》
