MAYISUMAI Dust Mask Respirator Anti Pollution PM2.5 Air Face Masks Washable and Reusable Dustproof Safty Masks with 2 Valves and 4 Activated Carbon N99 Filters Made for Men Women Outdoor Activities

I bought this dust mask because I work in a noisy and dusty environment. It was comfortable to wear for lengthy periods. The straps on the mask is slightly stretchy so you can adjust the fit. The mask stayed in position at all times and there was no need for me to readjust the fitting. It comes with 4 filters. There are no instructions on how to fit the filters onto the mask but it wasn’t hard to figure out. And the filters were easy to fit onto the mask. All in all, it did the job and I’d recommend these masks

Great product. Much better than the disposable ones and so much more comfortable. The nose band isn't just for looks and is actually adjustable which makes a lot of sense when you are wearing it. It comes with four filters which are a little tricky to fit the first time but as long as you have the filters the right way up you can't go wrong. Not sure how long the filters last but I'll be buying a few extras anyway. A nice 'no fuss' mask.

Great value with 4 charcoal filters, 3 more than a similar product I tried that was also more expensive. The main benefit of this mask is that it fits around the ears unlike others that just have one strap to the rear of the head which makes them uncomfortable when cycling. This mask works and is comfortable.

Bought for my dad as he often cycles tot the city. Not sure if he tried it yet but it seems solid and sturdy made. I think he looks much better wearing this than the industrial white anti-dust mask he used in the past. I'm gaply with this purchase. It also came in a nice box, can definitely be used as a present. The bonus is you get 4 matching filters with it.

This dust mask is far better than the usual disposable type. Everything’s adjustable so it fits perfectly and it’s extremely confortable, even when wearing it for long periods.The Velcro on the back is great quality and doesn’t get clogged up with dust, as happens with some other adjustable masks.I bought one to try, but I’ll definitely be buying more.

This mask is a convenient one to use for those who work in places where there is plenty of dust. I use it when a morning alert is very useful. The air it exits is not that cold and it makes me feel easier. It's easy to change the air cleaning kit. It's very light and comfortable.

The product doesnt fit securely round the face so slides down a lot. Because it doesnt fit properly air can get in from the sides, so defeats the purpose. It says it come with 4 filters but really it's 2 sets because the mask takes two at a time. Would not recommend.

I received this item today, with the intention to use it for a run today. But when I opened it, I went to fit one of the filters and I noticed that there was a valve missing on one side which meant I couldn’t fit the filter or use the mask.So unfortunately I don’t know how well this products works, which is a shame, I was looking forward to it
