Effective against pollution, fits well, comfortable for long duration
2 December 2018
An anti-pollution mask is a personal device, just like a shirt or shoes - different people have different choices and fittings. You should try various masks before deciding on one. For me, this one fits well. The strap is horizontal so it covers the entire head instead of being over the ears. Although it seems inconvenient to put it on, it is more comfortable to wear it for long duration. During inhalation and exhalation, the fabric pushes in and out, suggesting that the fit is proper and the mask is working.
