I dislike the fact that the product description does not tell us what size particles this mask filters! That is, it does not tells us the size of the smallest particles this mask will remove. That makes it impossible to know whether it will do the job we want it for or not! Furthermore, the "questions" section will not accept the simple question "What are the smallest particles this mask will filter?" In fact, given that no questions have been asked, it seems it may not be accepting any questions at all, whatsoever!I think I know the reason for the lack of information... The seller wants to sell this mask to as many customers as possible, without their knowing whether it will work or not, which might of course create a mortal hazard! If you buy and use this mask, you might wind up in a hospital - as a direct result!What a waste of time this has been. I hope this seller does not sell a single one. ### ⭐ First review is the truth *by A***S on Reviewed in the United States on March 15, 2020* No, it doesn’t. “Particulate matter” isn’t a measurement. This mask has no official rating. ### ⭐⭐⭐⭐⭐ Great mask *by J***N on Reviewed in the United States on March 17, 2020* Love this mask. It is an N99 and blocks small particles. It is very comfortable to wear all day, even when exercising. I did need to sew elastic loops to secure it to my head (my head is smaller than the mask was made for). It has no stinky rubber smell like other masks. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/184417442-mirstan-dust-mask-dustproof-safety-breathing-mask-respirator-activated-carbon](https://www.desertcart.us/products/184417442-mirstan-dust-mask-dustproof-safety-breathing-mask-respirator-activated-carbon) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-12*
