Frequently Asked Questions for Facemask

Q1: How many different types of mask are available?
There are 3 types of masks available in the pharmacies: paper mask (1 or 2 ply), surgical mask (3 ply) and particulate respirator (e.g. N-95).

Q2: How is the particulate respirator different from the paper mask?
The particulate respirator which is often used to protect against other highly transmissible respiratory infections such as tuberculosis, is recommended by the WHO (World Health Organization) and the Communicable Disease Centre in Singapore. It has the capability of filtering 0.3 um particle that is lacking in paper mask.

The face to mask seal of the particulate respirators is superior when compared to paper mask and surgical mask.

Q3: Do these masks offer 100% protection against SARS?
Particulate respirators are not a guarantee that the user will not contract SARS. The particulate respirators may help reduce exposure to airborne biological contaminants, but they do not eliminate the risk of exposure, infection or illness.

Also, the particulate respirators need to be worn before and during the entire exposure period for effectiveness; and the fit of respirator to the face is very important to ensure that the airborne contaminants will not penetrate the face-piece seal.

Remember, masks also serve to protect others from you if you are sick.

Q4: Can I use the same mask every day?
Manufacturers advise disposing and replacing the mask when it becomes damaged, soiled or when the person finds that there is some resistance in breathing. Since breathing will bring about condensation and will cause particles in the air to eventually clog up the filter system, the mask should be changed regularly.

Q5: I notice that surgical mask is cheaper, can I use that in place of the particulate respirator you mentioned?
Surgical mask can only offer protection to large water droplets like saliva from coughing and sneezing. The micro-organism implicated in this recent spate of SARS is identified to have a very small particle size. Plus the fact that the face to mask seal is not good enough, the protection offered by surgical mask will be minimal.

Q6: Can I spray antiseptic onto the mask to increase its effectiveness?
No. Any measure which has not been advised by the manufacturer may compromise the usefulness of the mask.

Q7: Can I remove the facemask for a while before putting it on again?
You should not touch the mask after it has been put on as the exposed part may contain virus.

Always remember that you should wash your hands with detergent or antiseptic soap before using and after removing the mask.

Q8: Is the mask for everyone?
All masks are designed for adults only. Do not use the mask if you have difficulty in breathing or feel dizzy when using it.

Particulate respirators are NOT recommended for people who have asthma, breathing problems and pregnant women. It is designed for use at health care setting.
