Anti-pollution City Cycling Mask Mouth-Muffle Dust Mask Sports Face Mask with Extra Activated Carbon Filters for Cycling, Running, Motorcycle and Outdoor Activities

i got the one from unhuafu1 vender, it is exactly the same as the one in pictures. took 5 weeks to arrive, only one filter, but you can buy spare filters and also spare valves elsewhere on amazon.i got a much dearer one from uk vender, that was also made in china and is very very similar. so if you can wait for delivery, go for this one. its stretchy but it fits my big head ok anyhow.

Nothing

my job insists we wear masks at all times when inside the warehouse. We are also expected to put on a mask or wear one when delivering to customers.I had previously bought a mask with. single vent, as when driving I frequently need to wear sunglasses, due to low sun or glare reflected from the road. a mask with a single vent made a noticeable difference to the amount my glasses fogged up.I was hoping that a mask with 2 vents would be even better.The design itself does not fit very well of may face, it stands proud and barely covers to just below my chin. Through the night I noticed drips of moisture being expelled, not very pleasant or reassuring for our customers.Your milage may vary, but I put it on at approximately 6pm on a shift and was home before 10pm, this mask hurt the bridge of my nose so much during that time that I still hurts 2 days later. the bag it comes in has fitting instructions which I followed, My nose looked like it was sunburned.All the included slip is in what I guess is Chinese and gives no cleaning/care instructions.The behind the head fastening mechanism was a lot more comfortable on my ears for prolonged wear but is far less convenient to take it off and have a sip of drink. From a single wear the amount of fluff picked up from my scarf, has made half of the velcro unusable. If you have long hair like I do you will need to tie it up.

Great material but cheap ventilation valves. A slight nugget on the twist valve would, make a cheap product look like a gold star.

overall a comfy product which fits securely and the nose piece can be pinched to fit better, the strap around the neck is comfy and does not irritate the neck. The filters are easy to change and seem effective. I am unsure how well the velcro will stand up to being washed on a regular basis but I assume not putting it in the tumble dryer will prevent it flattening out.

It took its time coming but worth the wait as its comfortable to wear and with the valves I find I am not 'steaming up' as I wear spectacles and basically why I thought I would give this a try. Plus as it included the cost of postage, so that's why I ordered it. Overall not a bad buy and it works for me

This mask was very cheap so should have realised that it would not be very good. I was very uncomfortable therefore I didn't wear it and before I even had the chance one of the filters dropped off.

Glasses steam up, other than that suitable for covid face cover. Not sure it's comfortable enough to workout with one on. Can be worn with neckstrap behind head so to take off and on
