Where to buy DS2 and DL2 masks online in Hong Kong this 2022

DS2 and DL2 masks are the Japanese equivalents of P2 masks.

The World Health Organisation recommends that a person wear a mask at all times when boarding or on board public transport, entering or present in an MTR paid area or entering or present in a specified public place. For more information, see the coronavirus section of the Hong Kong government’s website. There are several types of masks available in Hong Kong.

What are DS2 and DL2 masks?

DS2 and DL2 are Japanese standards for dust masks. DS2 and DL2 masks are disposable and consist of a filter, facepiece and headband. They filter the air as you inhale and release exhaled air through an exhalation valve.

Both masks filter over 95.0% of particles. The only difference between the masks is the method used to test their filtering efficiency.

DS2 masks

  • Tested using solid salt (sodium chloride)
  • Filters more than 95.0% of airborne particle

DL2 masks

  • Tested using liquid dioctyl phthalate
  • Filters more than 95.0% of airborne particles

Can I get DS2 and DL2 masks in Hong Kong?

While you can technically order DS2 and DL2 masks online from Japan, they’re not widely available. It’s much easier to find the equivalent P2 masks.
P2 masks offer the same level of protection and filtration and are much more widely used.

What’s the difference between a DS P2, FFP2, KN95 and N95 face mask?

When it comes to choosing a face mask, it can be difficult to determine the difference between types. According to respirator company 3M, P2, FFP2, KN95 and N95 masks are all very similar, though they do vary slightly in performance.

Depending on your location, different mask types are more widely used. For example, in the United States, N95 are common; in Australia and New Zealand, you’ll see P2 masks more often; in China, KN95 is the standard. Mask manufacturer 3M, which specialises in filtering facepiece respirators (FFR), offers the following explanation of the main differences between each mask type.

Each mask is also subject to various regulatory standards around the world, which means that, depending on where you live, one particular type of mask will be the most common. In Australia and New Zealand, for instance, the P2 mask is the most common, while in China, it is the KN95 mask.
