Why KN95 Face Mask
In the pandemic era, chances are you’re one of millions who are looking for a face covering that suits their needs. In case you are, don’t worry you’re not the only one who’s overwhelmed by the abundance of mask types on the market. Surgical, medical, FFP1, FFP2, FFP3, cloth, sponge are a few to name. However, usually there is no clue to what these names mean, what they are and what features make them different from each other. So, if you are understandably confused about making a choice about the best face covering that meets your requirements, this blog may help inform your decision in a straightforward way.
Amongst all other types of face coverings, the KN95 respirator seems to have plenty of traits that makes it pretty much superior to other masks. A KN95 face mask, also known as KN95 FFP2 or KN95 Respirator, usually offers higher levels of protection, efficiency, filtration and material. Moreover, kn95 respirators with breathing valve provide an extra level of practicality and convenience. A valved KN95 face might be a great choice for you if you’re looking for a face cover with enhanced breathability. A quality KN95 mask valve may help make exhalation easier.
Additionally, the valve helps prevent humidity and the build-up of heat inside the mask. This provides the valved KN95 mask with an advantage over other masks that can be significant to some especially those looking for a convenient breathing experience due to special conditions. However, at the end of the day, the choice of your ideal face covering is dictated by what you’re looking for rather than by what this or that mask does or does not have. Many perceived high standards might not be relevant to you as you may not need them.
Mask protection efficiency
When it comes to protection efficiency, a KN95 face mask can offer a staggering 95% safeguarding from viruses, and a perfect 100% protection from bacteria, dust, and pollen. In comparison, surgical masks seem to match the KN95 mask’s 95% protection from viruses. However, surgical masks don’t tend to be as efficient as KN95 respirators when it comes to protection from bacteria, dust, and pollen. They’re unlikely to offer more than 80% efficiency. Likewise, a similar level of efficiency might be available in the FFP1 mask that can provide up to 95% protection from viruses and is usually 80% efficient against bacteria, dust and pollen.
Nonetheless, other masks such as activated carbon, cloth and sponge can only offer limited levels of protection often ranging from naught to 50%. These can be an option in case a high level of protection is not required. The exhibit below quantifies the different levels of protection available from a number of face coverings against the same variables.
Nonetheless, face coverings cannot be just seen through the lese of protection efficiency. Other factors including filtration layers, filtration efficiency, durability and reusability together with other standards are usually considered. That said, the choice of the mask is largely influenced by who wears the mask and in what environment it will be used. In other words, the user and the area of use dictate the level of required protection and prompt the desired scale of safeguarding the mask needs to enjoy. A number of factors are normally accounted for. For example, the design of some masks creates limitation for their use. In contaminated environments such as healthcare settings, operating professionals obviously need high levels of protection which can only be offered through multiple layers of filtration.
In such an event, face coverings with a single layer of filtration such as sponge and cloth masks are unlikely to offer safe protection due to insufficient filtration efficiency. However, multi-ply masks like KN95 respirators can be a good option in such environments thanks to their efficient multi-layered filtration. Albeit, KN95 masks come in different counts of layers, usually over 4. Obviously, the higher the ply count the more efficient the filtration.
The 6-layer KN95 face mask is deemed as one of the ideal options for environments with potential contamination risk. Its reliability in such settings stems from the high level of filtration efficiency it is able to provide. Additionally, KN95 masks may offer more than 80% respiratory resistance. They can be possibly used for up to five times. Yet, the time of constant use of the respirator in none-dusty environments is generally dependent on hygienic and practical considerations such as contamination or bathroom usage rather than a pre-determined number of hours.
By contrast, other disposable face masks might not offer more than 3 layers of filtration generally combined with up to 45% respiratory resistance. Moreover, their usability is believed to be limited to up to 8 hours in many cases. This makes the KN95 mask a preferred option in risky environments as it can capture up to 95% of tiny particles and prevent their entry into the mouth and nose. Conversely, other disposable masks are only able to capture large particles. Some major contrasts among a range of masks including KN95 are displayed in the illustrations below.
