How to choose the right mask for the corona virus COVID-19?
Recently, the COVID-19 has increased rapidly in the world. From the US CDC and WHO,they mainly tell us that you should:
- Open the windown and keep the air moving and clean
- Chean your hand oftenly (use 70% alcohol gel or our Disinfectant Wet Wipes)
- Avoid to touch the wild animal etc
When you go outside, it is better wear a mask because the conoravirus is uncertain,you do not know if others is already had virus or not. And now an asymptomatic infection may also spead the virus.
Our company has received many inquiries from customers, most of them about N95 mask and its raw material. But is it necessary for ordinary people to wear N95 masks? The following details how to choose a mask.
Three-layer mask(3Ply disposable Face Mask): composed of three layers of non woven fabrics
PP spunbond + Meltblown + PP spunbond
Outer and Inner layers are made of PP spunbond nonwoven fabric: liquid splash-proof and water poor.
The middle layer (filter layer) is a meltblown non woven fabric.and the materials are BFE90 meltblown,BFE95meltblown,BFE99 meltblown,N90 meltblown,etc….
If the outer and inner layers of the mask are made of SMS non-woven fabric, the level of the mask will be higher.The higher the filtering level,the greater the ability to block viruses.
KN95 mask and N95 mask
The N95 mask is one of nine particulate protective masks certified by NIOSH (National Institute for Occupational Safety and Health). N95 is not a specific product name. As long as it meets the N95 standard and passed the NIOSH review, it can be called a N95 mask, which can filter particles with an aerodynamic diameter of 0.075µm ± 0.020µm and achieve an efficiency of more than 95%.
KN95 masks /N95 masks can be interpreted as masks that can meet national filtering standards.
In fact, the filtering effect of KN95 is the same as that of N95, and it can also be understood as KN95 = N95.
The “KN” or “N”letters stand for national standards, and the “95” numbers stand for filtering levels.
N series is American standard.
KN series is Chinese standard.
FFP series is European standard.
KF series is Korean standard.
“85”，“90”，“95”，“99”，Represents the level of filtering
It is easier to understand with a formula:
KN99 ＞ KN95 ＞ KN90.
N99 ＞ N95 ＞ N90.
BFE99 ＞ BFE95 ＞ BFE90.
FFP3 ＞ FFP2 = N95 = KN95=KF94＞ KN90.
N95 / KN95 is not a specific product name, as long as it meets the N95 / KN95 standard mask, it can be called N95 / KN95 mask
In general, to resist viruses（COVID-19） and flu, the N95 series is sufficient
N95 is produced according to the American standard NOISH, the manufacturers are 3M and Honeywell; FFP2 is the European standard EN149;KN95 is the Chinese standard GB2626-2006. All three types of masks are qualified masks. SImply you can see the photo as below as well:
How to choose the mask you need and protect yourself.
Reduce outings and parties. It is enough to wear three-layer masks when going out for shopping. Of course, if you wear masks with high filtering level, the safety will be better.
Service personnel or people working in the illness, such as police officers, supermarket service personnel, etc. This type of people has more contacts, and it is recommended to wear masks with high filtering levels, KN95 mask / N95 mask / KF95 mask / FFP2 mask.
High-risk personnel, nurses, or doctors. Must to choose a mask with a high filtering level. In addition to KN95 mask / N95 mask / KF95 mask / FFP2 mask.In addition to these masks, you can also choose FFP3 mask, N99 mask, KN99 mask, etc.
You can keep your home ventilated, wash your hands frequently, and measure your body temperature every day. If you find that your body temperature is too high, consult your doctor in time. Wearing a mask not only protects yourself but also others.Providing your own lifting power is also a protection.
