OxiClear N99 Anti Pollution Face Mask with 4 Activated Carbon Filters & Detachable Headband D.R.D.O Certified (Black)

Awesome

Very comfy, soft, adjustable , breathable and they also give you four extra filters that you can change after a few weeks of regular use like for outdoor its the perfect mask the one thing i like abt it the most is that foam bit for the nose thats adjustable, i don't really use the back strap cause it feels a bit excessive the side one are enough and adjustable so perfectly fine. Worth your money

It's awesome product, must buy if you are living in Delhi like region, fitting is very good and product quality is premium, best part is it made in india product and company is also indian if you support indian product must buy it

The round band in the third photo is what keeps the tightening grip of the band in place. But that round band at the end of the ear band is poooor quality. It came off upon first use. Because there circle thing had a gap so it slipped

Fit on face. Effective work.

The protective mask has insufficient size, so it either inadequately covers the nose or the chin. The necessary size should be such that the upper edge of the mask overlaps the bridge of the nose, almost under the eyes, and the lower one reliably covers the chin. If this condition is not met (which is the case with this product), the mask does not provide a tight fit to the face. As a result, during inhalation, dirty air enters through the gaps between the mask and the face, bypassing the filter.During exhalation, the air should exit through the specially designed built-in exhalation valve, but this also does not happen because the valve is located behind the filtering element, which creates resistance. Thus, exhaled air is expelled through the existing non-sealed areas (described above), as it is evidently easier for it to exit through the gaps than through the filter element and the valve. If you wear glasses while using this mask, be prepared for them to fog up due to the exhalation flow.Achieving a snug fit of the mask to the face is almost impossible. The best fit requires significant tightening of the lacing. However, this causes pain on the bridge of the nose after 5-10 minutes of use.The positioning and size of the filtering element do not provide quality air filtration, even if you tighten the lacing strongly and ensure the best fit of the mask to the face. The reason is that the size and position of the filter element allow inhaled air to pass around it.After two hours of work in a dusty environment with this protection, the entire inner (mucous) surface of the nose is dirty, and over time, dryness in the throat and coughing occurred.A regular white KN95 mask provides no worse (and often better) protection.Despite expectations from this protective mask, my purchase turned out to be extremely disappointing.

Fitness should be improved further by nose spring more rigid, sothat no fine particles/air can enter through nose/eyes in between area.Apart this is a nice product. Filters pungent smells also. ( it has carbon filter).

Good quality long lasting. No issues after washing. Fits good on medium size face. Price should be a little low
