Information

BFE99 is enough for people's daily protection. From the perspective of the filtration principle, the filtration efficiency of BFE99 masks for virus-sized particles is not bad.

customized BFE99
Many people understand the filtering standards of masks very mechanically. For example, when they see BFE99, they think that they are only useful for bacteria of 3 μm and cannot filter viruses of 0.1 μm. In other words, compared to BFE 99, when you see a mask targeting PM2.5, you think that it is targeting 2.5μm particles and cannot prevent viruses. So blindly pursuing N95 or VFE99 is not the case. BFE 99 can have high filtration efficiency for 3μm, high filtration efficiency for PM2.5, and 0.1μm filtration efficiency is not much lower.
About nowadays masks, such as BFE 99, no longer use the principle of "sieve". It is "active adsorption". The mainstream material of BFE 99 is called "electret meltblown electrostatic adsorption material", which has an electric field inside, which can attract particles passing nearby. With this adsorption characteristic of BFE 99, the blocking ability of large particles and small particles is similar, and even when the particles become very small, the filtration capacity will be improved.
Through the above introduction and analysis of the Interpretation of the adsorption capacity of BFE 99, hope it helps you.
