ResproTechno Anti-Pollution Mask - Extra Large - Black

This mask is an Amazing mask . I am not a Dr or anything. One thing I can attest to , this mask has given great protection to my husband after 2 Bone Marrow Transplants he has worn it through this pandemic has stayed healthy. I am not saying this is the only reason he’s stayed healthy as he is extremely careful takes other precautions , uses other things with it to protect himself.It is thicker , it’s comfortable it’s not the the easiest to breath through what many fail to think of is the protection this mask provides . This mask was recommended by Dr’s to my husband.Crazy thing this is the 3 rd mask we’ve purchased 2 weeks after receiving the new mask he dropped it out of his pocket getting into the semi and lost it.There’s not even a second thought to purchasing a different kind of mask even with the cost being what it is . If it’s protection your looking for along with comfort this is definitely your mask .Sizes are important ! My husband wears a XL we bought a L had to exchange it years ago .He washes his by hand , air dry overnight. We always use the filters that are for this mask.You get what you pay for with this mask and filter.Thank You for making this mask ❣️ I know it has protected my husband and others .Greatly appreciated

TO BE UPDATEDI have been testing out various masks on and off for the past month, and I have to say I love the utility of this mask.It does a great job of blocking out smells and allergies, and I use it around my friends who smoke and don't "taste" it.Which leads me into a few bad things about this mask. When I use it, my nose is usually blocked up, but breathing through your nose with this mask (regardless the size) seems to be difficult at best. And since it only has a single strap wrapping around your neck, keeping it in place and proper tends to be hit and miss.It is comfortable and after a while of wearing it, the sweat that builds up isn't too noticeable.More to come as I continue testing it.

I have COPD and on oxygen 24 hrs day. I also have really bad allergies. When you combine these two issues together and any one or more of the ozone, particulates, and pollens range into the yellow or higher, I cannot go outside. With this mask and filter I have been able to go outside and walk with no affects of allergies or the weighing down of my lungs from the pollution or ozone. I use this with my oxygen canula without issues. Of course there is more effort to draw air in through the mask than there would be without the mask, but I am hoping it will help to strengthen my lungs more.Great product and great - quick - seller!

Fits fabulously, and is comfortable all day long.Just make sure you remember to unscrew the valves, and take out the filter, before you hand-wash the mask itself with a drop of dawn liquid soap. Rinse repeatedly in lukewarm water, then air-dry in a warm, well-ventilated room before you use it for the first time.

I haul coal for a living and when I go to unload I tend to end up breathing in a lot of "dust" in the air... this is an issue weather it's coal or dirt, most dust masks suck into your mouth or nose causing it to be difficult to breath...since beginning to wear this filter system I have been able to breath better both as I work and after... and yes heavy use requires Monthly replacement of filters!

If it is humid or raining, this thing cause asphyxiation. I noticed it hard to breathe in dry stints as well, enough that it caused a lot of yawning, and a pull over to the side of the road in order to pull the filter.The nose piece is nothing like the one in their foggy mask, which worked well for me in the past.Tried to return, they want you to pay shipping and a re-stocking fee.(edited for spelling and clarification -Bryan)
