KN95 Face masks are a symbol of the pandemic era – a visual metaphor for the tiny, unseen viral foe that could be lurking around any corner. Some opt for a scarf wrapped around their face, others make do with a t-shirt yanked up over their mouth. The more creative hook colourful homemade varieties around their ears, while a lucky few wear distinctive surgical masks or, rarer still, KN95 respirators.

1. Whether to wear KN95 mask

If you have symptoms such as coughing and sneezing, wearing a kn95 mask is proved to be highly effective in catching the droplets, and therefore might help prevent the spread of viruses.


The effectiveness of wearing a kn95 mask to protect yourself from contracting viruses is thought to be very limited. If you wear a kn95 mask in confined, badly ventilated spaces, it might help avoid catching droplets emitted from others but if you are in an open-air environment, the use of kn95 mask is not very efficient.


Of course, professional disposable masks (such as N95 respirator and European equivalent FFP-2 respirator mask) can filter out particles from the air. They are designed to passively filter out 95% and 94% of airborne particles when the replacement breathes-a minimum of 0.3 microns.

Some earlier studies have shown that more viruses than expected can leak through the N95 filter, but it has been found that they can effectively prevent influenza viruses.

2. What does KN95 mean on a mask?

An KN95 respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles. The'KN95' designation means that when subjected to careful testing, the respirator blocks at least 95 percent of very small (0.3 micron ) test particles.

What You Need: Lighter

Put on yourKN95 mask

Hold and activate a lighter six inches from your mouth

2. Empty the contents of a pack of Sweet and Low on a spoon or flat surface

3. Try sniffing with the mask on and the mask off, noting any difference

Certified mask: You catch the fragrance, but only faintly.

Poor quality mask: You can still smell the saccharin in full force.


Test 3

What You Need: Water

1. Hold yourKN95 mask by the elastic bands, with the inside of the mask facing up

2. Fill the mask with water

Certified mask: The mask cups the water with zero leakage.

Poor quality mask: Water leaks from the mask.
