NBDIB 4 Pack Unisex Adjustable Reusable Dust Face Protection with 8 Carbon Filters and 8 Breathing Valves for Bicycle Riding Running Cycling Outdoor Sport Black

They can be a worthwhile protection if you use them with one of the activated charcoal filters,but at this stage in the Pandemic there isnt a nationwide government mandate to wear a mask whenever you're not in your residence so charcoal filters and replaceable paper filters arent that neccessary.But masks that can do that,like these,are high quality and most of them have a cup shape with enough room to cover you very thoroughly.8 sets of masks for $35! You cant get 8 decent pantyhose for $35,anymore,just the ones that'll run while you're putting them on.

These are great for teens and individuals with. Smaller head. They are uncomfortable around the ears and after a long period of time, they start to fall down your face.

I love these but it’s a little tight around the ears and if I keep it on for about 30/40 minutes I have to take it from around my ear and rub my ears gently because it hurts so bad. Maybe it’s made for teenagers and not adults.

Strap came off during my workout but the loop around the ear prevented the mask from falling off my face. Decent for large particles in the air but not meant for smaller particles or viruses. Material of the mask feel cheap but breathable on the side, which some people may feel discouraged about. The filter is fine and the valves as well so you get your money's worth from them. Overall, if you need something for doing daily activities with heavy particles in the air then it does the job. Just be warned that these masks aren't meant to last.

I am happy with these, they are more than i expected, the assembly was tricky, the instructions weren't too informative, but once i figured it out it was a 'breeze'. These masks, I feel, were a great bargain for the price. (wish they came in different colors). They are very comfortable and breathable, don't fog glasses and work very well for my husband who has COPD.

They are too small and they don't fit a man's face. When I tried the first one on the straps over the ears broke. These are total crap and not worth wasting money on

The design is good and comfortable but, keeping track of the valves is a hit and miss. You loose them as they don’t stay attached to the make & filter when you are active using the mask. Not a bad idea for the protection they provide.

Takes a minute to figure out where to position the strap behind the head, but once you figure that out, it's a nice mask. I like being able to quickly unhook from my ears and leave it around the neck, when needed.
