Wearing a mask can play a role in preventing pm2.5, but the premise is to choose the right mask.

People tend to have a misunderstanding when choosing pm2.5 masks, thinking that N95 masks with high filtration efficiency are good.

But in fact, this opinion is not right.

Even if a N95 mask has a high filtration efficiency for particulate matter, if the respiratory resistance is too large, it will not be a good respirator with good performance. 

For example, the common N95 mask on the market has a good filtration effect, but the respiratory resistance is very high, and if you wearing it for a long time, it is easy to cause hypoxia and discomfort.

In the mask, the meltblown nonwoven fabric (China medical meltblown fabric vendor) is a important role as the filter layer.

Non woven fabrics also rely on electrostatic effects to adsorb and capture fine dust particles. Of course, it has the trapping effect of ordinaryfilter materials. So it can better block PM2.5.

Usually the supplier will use 40-50gsm meltblown fabric (melt blown material manufacturer) for N95 mask.
The thicker for the fabric, the respiratory resistance will be more

 butnot good for people wearing the mask for long time.

And for black color meltblown fabric (China melt blown material custom) ,the filter efficiency will be weaker than white color meltblown fabric.

A good performance of respiratory protective equipment, must be the end product of with high filtration efficiency and low respiratory resistance . Both of the features are very important.
