3M 9004GV Anti Pollution Mask (Pack of 3, Grey)

this really protects from pollution. I got them for me, my son and my father. we are roaming so freely on the road now. If there is dust, it cannot touch us, if there are lot of dragon flies in the night, nothing will happen, you can drive through them, without feeling a thing. Only problem I faced was, I did not understand how to wear them. we are wearing only top part of it, all last week. Just now i saw a video on how to wear this. First you wear the top flap behind the head and then come to bottom flap. Place bottom flap, on the neck below the hair. Great product, we breathe so comfortably. Its good for 22 days, if used 4hrs per days, so that's pretty good deal. Go for it.

Used it for more than a month. It does make you feel difference when you use this. But it is very uncomfortable , the joint of string with mask is if staple which ofcourse pricks your skin and leaves marks on your face. Also nose clip initially gets adjust but after fee use it becomes useless also again it's uncomfortable . Well conclusion being do not buy if using for daily use , u get much better mask. But for occasionally using u can buy considering price

Very good

DO NOT BUY नकली है ये। प्रदूषण रोधी साँस छोड़ने वाला वाल्व किसी काम का नहीं है। सारा गाड़ियों का धुआं, कूड़े की बदबू, सिगरेट का धुआं, कुछ भी नहीं रोक सका ये फिल्टर मास्क पिचले 2 - 3 दिनो में। Filter is useless: The anti-pollution exhalation valve is useless. This filter mask has been unable to block out vehicle exhaust, garbage odors, cigarette smoke, nothing in the last two to three days. रुमाल इस्से बेहतर रोक रहा था प्रदूषण।

Good product

So these are very cheap and effective masks in the market. They have an active carbon filter and can be used as an anti-pollution mask in medium to heavily polluted areas. It blocks all the dust and harmful particle in the mask filter and gives you pure air to breathe. Although they are little fragile as they have strips which if no taken care can be easily damaged making it of no use. You can use one mask for 20 -30 days in medium pollution areas, if you are living in metro cities you should start using these or other masks, but not that black colour which you will find in streets as they are of no use.

I did not quite understand what exactly those white square filters are doing, but they do not pose serious impediment to the ease of breathing. Folded mash fits nicely in small bag compartments. Can be reused multiple times and lasts long time. I have it in bag for close to an year now, kept as emergency for wind storms. I also use it while doing cleaning inside house (ceiling, laundry, spray work). It can not be worn for long time. It slightly suffocates and sweats. For about 10-20 minutes, it is bearable.
