- What is important to know before buying?
Respiratory masks of this type can be found on sale under different labels – it all depends on the country of manufacture:
N95 is the standard marking used in the United States;
KN95 – marking used in China;
FFP2 is the EU labelling standard for protective masks.
All masks with such numeric and alphabetic values on the packaging are absolutely identical and have the same characteristics.
On many models, two markings can be found simultaneously, for example, Leader Clean KN95 / FFP2 is marked both according to the Chinese standard and the EU standard.
The letters and numbers in this combination carry certain information:
N – rating class. It means “Non-Oil” and means the use of a respirator in a working environment with an abundance of harmful particles on an oil-free basis.
95 – the protective agent has an efficiency of 95%.
KN95 masks are a respiratory protective agent designed to provide a very tight fit to the skin of the face and effectively filter particles in the air, including bacterial ones.
Thanks to the internal filtering layer of non-woven polypropylene fibre, they are able to filter out up to 95% of hazardous particles of 0.3 microns in size: dust, moisture drops, vapours.
Block the entry of biological fluids of the mask carrier on others, for example, when coughing or sneezing. At the same time, the negative impact of small aerosol particles coming from outside is reduced.
Duration of wearing is about 6-8 and in some cases up to 10 hours, instead of 2-3, as with ordinary disposable masks. But in that, and in another it is not recommended to use a remedy repeatedly.
Due to their functional characteristics, these respirators are used by health workers who are in direct contact with patients with suspected infection or already infected. In domestic conditions, they also established themselves as a reliable means of protection and arouse the trust of users.
What is important to know before buying?
It is worth considering that those characteristics that guarantee increased protection for these respiratory masks can cause some inconvenience.
They are thicker than a normal medical mask, so some may initially experience discomfort or shortness of breath. Also, in comparison with sterile surgical and non-sterile procedural models of masks, KN95 respirators accumulate moisture faster due to their density and become hot during prolonged use, the effect of a “sauna” occurs. Some models have exhalation valves that can facilitate breathing and reduce heat build-up.
Respiratory masks of this type are designed to fit snugly to the face in the cheeks, chin, nose. Therefore, it is better for owners of a thick beard or a lush mustache to get rid of them while wearing, so as not to reduce the effectiveness of the protection.
An adult respiratory mask KN95 will be useless for a child – due to the difference in size, it will not be possible to achieve tight contact with the skin and reliable fixation.
And remember – any, even the most reliable mask gives the desired effect only in combination with other security measures. To avoid infection with COVID-19, observe personal hygiene, avoid being in crowded places, and in case of the emergency visit, keep a distance of at least 1.5 m.
