Basically this is a BFE (3.0 Microns Bacteria Filtration Efficiency ) >95% Mask. It is most likely a 2D flat base with 3 layers. Basically this is considered as a regular face mask that both US and Europe has higher standard requirement then this.
Other test standards go along with this mask will include:
GB/T 15979 for one time use hygienic standard. GB/T 16886 for In-vitro Cytotoxic, Skin Irritation /Sensitization (ISO 10993)
This mask standard is a bit mood because it is BFE > 95% and PFE ( Particle Filtration Efficiency ) > 30% only. Which doesn't match another standard in the US or Europe. But it does include the fluid-resistant test and the flammable test.
These two standard could be confusing but their filterability is basically the same. The only difference is the fluid resistance test with GB19083. In the US NIOSH standard it should be called Surgical, and the Europian standard is Type R. Chinese has 3 levels from PFE KN95 > 95%, KN99 > 98% KN100> 99%. So KN95 is basically the same as N95, N99 similar to KN99 and N100 similar to KN100. Europian FFP1 starting with > 80% FFP2 > 94% and FFP3 >99% .
China only has Surgical Mask which is only 30% PFE and F2100 Level 1 is 95%, Level 2 is 98% and Level 3 is the same with hight fluid resistance. So you are highly unlikely to find ASTM 2 or 3 in the market unless they are US-specific factory.
Europian Standard use their sharp to different the two standards so EN14683 is basically the Medical Mask with no PFE filter just like China YY/T0969 . has Type I, II, III and representing 95%, 98, 99% BFE. And EN149 is the cup sharp respirator with PFE over 80%, 94% and 99%.
The Europian standard surgical fluid-resistant represented by Type R at the end. For example, EN149 FFP2 Type IIR is basically the same as Surgical N95 and GB19083–2010 Level 1.
If we are going outside but not an enclosed environment, a Medical face mask should be enough to stop droplet getting into our system. Even the filter is not PFE > 95% the static of the mask will able to attract virus in the aerosol. If you are going to a room for a longer period of time, a KN95 would be better which is PFE > 95%. If you are medical front line that requires staying in a high viral loan environment for a long period of time, the N95 with a surgical face mask at the front can help extend the usage duration. For ICU it is better Surgical N95 or above and Surgical Face mask at the front or a face shield.
No they protect you too. We are the only country that says this. In Asia it is commonly understood masks protect both ways even regular non particulate masks.

- Soft feeling and comfortable, thicker And not rough than what I got from Walmart
- Nose piece flexes/molds very well
- straps are sewn in, they don't pop off if you put too much pressure on them
Great quality and great masks for daily wear. And the price is right (Walmart is $18 for 25 masks that feel much lower quality)
