Where to buy P2, N95 and KN95 face masks online in Singapore 2021

N95 face masks, also known as respirator masks, are designed to filter out fine particles from the air. They can protect wearers from things like smoke, dust, fumes and — in some cases — airborne illnesses if properly fitted and airtight.

As of April 14th, the Singaporean government has made it mandatory to wear a face mask when leaving your home to combat the coronavirus outbreak. To enforce this, a fine of $300 will be issued on the spot to first-time offenders and for repeat offenders, higher fines will follow or you could even face the possibility of court prosecution. Protect your health, the health of others and your wallet. Here’s where you can easily order these masks online.

For example, in the United States and Canada, N95 are common; in Australia and New Zealand you'll see P2 masks more often; in China, KN95 is the standard.
