N99 Anti-Pollution Reusable Face Mask With 20 Activated Carbon Filters & Detachable Headband D.R.D.O Certified For Unisex (Black) (Pack Of 5)

Using for 1 year and it is a good product.

Product was great and breathable. Have to test it in my work place to see how much is it worth. I think the price is very high and should be lower seeing the quality. Easy to wear and size is adequate, the nose clip is just right. Hope they lower the price to make it more affordable.

Bought the OxiClear N99 mask from Amazon and I’m really happy with it. It’s very comfortable to wear, made with soft fabric, and feels like good quality right out of the package. The fit is snug without being irritating, and it’s effective while still being easy to breathe in. Overall, a useful and reliable mask that does what it’s supposed to do.

Good quality but the price is ridiculous at 700

Recieved in good condition.

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.

Good but nose sponjh I've already lost once I wash the mask,also the back belt which holds the mask is also sticker damaged when alwash gently.

Just for for it...very comfortable
