What you need to know about masks

Masks are coverings that cover the wearer's nose and mouth. There are different types of masks:To get more news about quality medical surgical mask factory outlet, you can visit official website.

It is important that the mask is worn properly over the nose and mouth and removed properly to protect yourself against COVID-19. Watch this video to find out more.Face masks such as cloth or fabric masks act as a simple barrier and work as "source control"[1].

"Source control" refers to preventing the wearer's respiratory droplets from travelling into the air and onto other people when the person wearing the mask coughs, sneezes, talks etc.

These are not suitable for use during medical and surgical procedures in healthcare facilities, where exposure and risk of transmission of infection is higher. These masks may be used by the general public and in community settings. Please refer to MOH's guidance and FAQs on the use of masks.

Face masks are not regulated as medical devices under the Health Sciences Authority (HSA). Therefore, the quality and effectiveness of face masks are not regulated by HSA.For greater effectiveness, choose face masks that have good filtration capability. Examples of such masks include those distributed by the People's Association and Temasek Foundation.

Do not choose masks with exhalation valves, as these allow the escape of exhaled droplets from the wearer and exposes others to the risk of infection.

Face masks with good filtering efficiency help prevent people who have COVID-19 from spreading the virus to others by acting as a "source control". Wearing a mask in public places limits exposure to respiratory droplets and large particles and reduces the risk of community spread of infection[2]. This is especially relevant for asymptomatic or pre-symptomatic infected wearers who feel well and may be unaware that they are infectious[3].

These masks are particularly useful in public settings (e.g. when using public transport) when strict adherence to safe distancing may be challenging.Surgical masks are medical masks that offer both "source control" and protection for the wearer against exposure to splashes and sprays of infectious material from others. Therefore, in situations where an individual is in contact with an infected or a potentially infected individual (e.g. visiting a clinic for consultation, patient care givers) a surgical mask is recommended.

Surgical masks offer high filtration efficiency, adequate breathability and reasonable fluid penetration resistance. Their performance characteristics are tested according to a set of standardised test methods based on international standards such as ASTM F2100, EN 14683, Singapore Standard SS 669 series[4] or equivalent to verify that they meet prescribed requirements for bacterial filtration efficiency (at least 95%), breathability, splash resistance etc.

These masks, which are used during medical and surgical procedures in healthcare settings, are regulated as medical devices under HSA.
