Good product, the best part is neutral smell. After wearing for few hours there is no bad smell because of the activated carbon. The elastic is of good quality. Please increase the elastic length by 5mm. The seller needs to be educated to pack a surgical mask. It came in an envelope and inside the box was torn apart.

Its fairly good at filtration, a little more than the single layer masks available in the local medical store.However, there are some caveats-1. There is a 'not so mild' smell of some chemical which lingers on for around an hour when first using a mask (each mask can be used for up to 8 hours). This may irritate people with sensitive noses,or allergies.2. Gaseous fumes (like CNG fumes) which are prevalent in 'non polluting' roads like Delhi, do not seem to be adequately filtered. Similarly petrol fumes also come through. It is difficult to say whether it is an absolute fail or not, but it has to be better than nothing at all.EDIT AFTER 2 WEEKS OF USAGE- After 2 weeks of wearing it in peak traffic, I have made some changes in my review-1. The initial smell of chemical can be reduced a lot by roughing up the mask before wearing it, and leaving it out of the box for a day.2. Even though smells, and some fumes do come through, it does seem to have a good effect. The nasal discharges I used to feel when in peak traffic (which then continued for the rest of the day), has dramatically reduced. Though I can't say if it''s successful in filtering CNG fumes or other toxins, it does have an impact. And that is what matters.3. When wearing it, I found it more effective if the mask is put on the nose and lips without pulling it over the chin (as the product image suggests). That is, it seems to be more effective if you do not stretch out the pleats (folds) on the mask. Leaving the folds as they are, seems to act like a dual layer, which is more effective. Its practical, after all, its my nose which needs the filtration, not my chin or neck. And as long as I am not breathing through my nose, I am fine.4. I have worn it for up to 12 hours, and it seems to be effective for around 10-12 hours in reality, when the mentioned limit is 8 hours.

The product is overall good. But in 2 in years the price has tripled. :) May be covid19 demand. This is not fair.I purchased it in 2018 for Rs 250 for 50 pieces. Now its Rs 750 for 50 pieces.

Second Buy ...worth every paisa.Firstly Thankyou amazon for the timely delivery and pricing.I am a bike rider with an avearge of minimum 80 kms a day riding between navimumbai n mumbai city.after a lot of research, i came accross this mask on amazon, read t reviews and though of buying n trying them.My experience with the filtra carbon activated mask after riding around 128kms on one mask in one day, temperature usage around 29 to 34 degrees in n around mumbai city n highway use. humidity over 90 percent(as it also did rain at some places where i used it).Does it filter dirt? yes i does the way manufacturers claim.Does it filter odours while riding? yes to a large extend. i did get t usual petrol fumes, carbage truck stink ahead, heavy unburnt diesel from trucks n buses...but only for t first 1 second and the mask carbons pull off the bad odours....very effectively.size fits large head/face ppl.it does cover your nose and mouth very well.the elastic bands do come out at times if u pull hard, just use t staplepin.the elastic band did over the time gave me a skin burnt on the back of my leftear when i was constantly lowering the mask with helmet on,to speak at stops to find my way...i believe over time my soft skin will get use to it.i have found that its not that hot or sweaty on the face even in hot weather and high humidity.Verdict, highly recommend for riders to use on polluted highway and city .Cost effective even if one is used daily, hardly works out to rupees 4 a day, what is more important then your health !i forgot to mention i use a open head/ chinless helmet. i have not tried it in a close faced helmet yet, but am sure it wornt be hot with this face mask inside.

Good stuff.. Works perfect in bangalore's muddy roads. Even though the pack says "Do not reuse", I still use a mask for 2-3 days.Pros: Works great against dust particles, Cheap. Now whenever I don't use this mask, I quickly get a cold. That means the mask worksCons: The fit could have been even better.

Good quality masks. I have always bought FILTRA brand.

Quality is equivalent to 3M in surgical mask form factor. Good for upcoming Mpox and general purpose. Good Going! Will purchase again.
