Structure

Unlike the masks that have been in use previously, these two have a 5-ply layer. They are made of a soft non-woven material that can stretch to fit the contours of your face. You, however, should ensure that your mask fits your face well to give your mouth and nose the maximum seal.

Effectiveness

When you want protection from viruses such as corona virus, particulate matter, odors, and other microbes, the kn95 and kn99 have proved to be effective. In comparing Kn95 vs Kn99, it is clear that both the masks are highly effective in filtering the air. Kn95 is 95% effective while Kn99 is 99% effective.

Both can filter the particulate matter as small as 0.3 microns. They also come fitted with a carbon 2.5 pm that increases their effectiveness. It is imperative to note, however, that they do not protect you against oil-based contaminants.

Weight

The non-woven material used to make the Kn95 and Kn99 masks is feather-light. As a result, the masks do not exert any pressure on your face, which makes them exceptionally comfortable to wear. They are also firm but elastic to ensure that each mask conforms to your facial features.

Let us now consider the differences of Kn95 vs Kn99 masks:

Durability

You can use the Kn95 mask for up to 8 hours. Therefore, in case there is a limited supply of masks, such as during an epidemic, you can reuse the kn95 mask after decontaminating it.

Unlike the Kn95 that you can only use for 8 hours, you can wash and reuse your Kn99 mask. You can also wear it for between 48 – 72 hours. This is because the Kn99 mask is made to last for as long as 200 hours before it can wear, tear, or lose its effectiveness.

Reusability

Unlike the Kn95 mask, the Kn99 mask can be washed using water and soap. You, however, are advised not to wash it if it is soiled, when you notice that it has lost its structure, or if it is torn in any part. Your concern should be in the ability of the mask to protect you against contamination and not in how long it will last.

After washing your Kn99 mask, hang it to dry under the sun and avoid using if it is moist. Moreover, allow it to remain under the sun for longer because it decontaminates it further.

If you are using the Kn95 mask, however, do not wash it with water and soap as you do with reusable masks. To decontaminate your kn95 mask, put it under 750c heat for a minimum of 30 minutes, spray it with vaporized hydrogen peroxide, or decontaminate it with Ultraviolet Germicidal Irradiation (UVGI).

Filtering Ability

The Kn95 mask filters up to 95% of all contaminants with a thickness of 3.0 microns. The Kn99 is more effective since it can filter 99% of particulate matter that is 3.0 microns thick. The carbon filter fitted in both of these masks makes them very effective in protecting you against toxic matter in the air.

The two masks will also shield you from unpleasant odors, especially those associated with health facilities. They also filter larger particles such as dust.

Breathing Resistance

While reviewing breathing resistance for Kn95 vs Kn99, we realized that the Kn95 can withstand more breathing pressure when compared to the Kn99. This means that should you sneeze continuously when wearing the Kn95 mask, it is less likely to tear. The Kn99 mask, on the other hand, will tear more easily if you sneeze continuously while wearing it.

The Kn99 has a valve that allows air to pass through it more easily. You, therefore, will struggle more when pulling air into your nose when wearing your Kn99 mask as compared to when you are wearing your Kn95 mask. Even with more breathing resistant, however, it is important to note that the discomfort that this causes is bearable.
