Yugan N99 Anti Pollution Reusable and Washable Face Masks with Replaceable N99 Filters, Unisex, With Valve

Nice

The mask is good, but it's thick and if you are a specs user it can be very uncomfortable for you.It's an excellent mask only for those who don't wear specs.

Very good

Thickness of product is so good really value for money colour is so good and durable product air flow very easily

Over All good

Not a mask I'd recommend for an adult. For petite adults or children its possibly ok. The size is really small and doesn't cover efficiently. The overall quality seems great, no issues there, it's not perfect but does reduce dust while wearing, but due to the size issue it wasn't certainly not doing the job it could do if the size was larger. The air valve works, but placement is not ideal due to the filter being behind it. The valve is one way so moving it to the side would improve it's purpose. For comparison I photographed over a standard sized n95 and added a ruler.
