The rest will fall in the small category." I assume that the reason 93% fit medium to large because men typically are the users. I am 6', 225lb guy that wears a medium. My 5'4" wife uses small. I can almost wear a large, but larges are set for people with long faces. **Q: What filters come with it?** A: None - you order the filters separately. There are several/many different filters depending on what your application is. Simply sawdust? Chemical fumes? Buy the filters that fit your use. **Q: Even after reading the q&a i'm still confused as to which filter i need. i just need dust particle filtration for woodworking. shape/model #?** A: A set of the 3M P100 filters work great. I use the 2091 model for woodworking. The P is for particulate and the 100 means it filters 100%. For anything with fumes like finishes I use a paint set of filters like the 3M 6001 **Q: What is the difference between this mask and the 3m(tm) half facepiece respirator assembly 6291 ?** A: This one is made with silicone that seals against your face which is more comfortable and durable. If you plan on wearing it often or for long periods of time get this one. ## Customer Reviews ### ⭐⭐⭐⭐⭐ a must have to keep you safe *by on Reviewed in the United Kingdom 30 October 2025* works well no detectable odor in mask ### ⭐⭐⭐⭐⭐ Great mask *by on Reviewed in the United Arab Emirates 14 November 2020* More better than the previous model. ### ⭐⭐⭐⭐⭐ COMFORTABLE, SIMPLE AND PROTECTIVE (The best one for me) *by on Reviewed in the United States 4 June 2015* MOST COMFORTABLE DESIGN. SOFT SILICONE, with simple features that don't cake up with saw dust in the shop. THIS MASK IS AMAZING, however, many other reviews and the 3M description cover most of that..COMFORTABLE FIT AND QUICK RELEASE. Soft silicone face mask easily conforms to many shapes of face.. This (LARGE) one is large enough to fit comfortably on my big mug. So too small is no good for me, and the medium didn't work for me. I like masks to ride on top of the bridge of my nose. Remember, it doesn't matter as much how good the customer service is, nor how the shipping and packaging are..WHAT MATTERS IS.. HOW DOES IT FIT!!Fit and size is all that matters here.. Measure your face and look at these photo measurements, and compare..MEASUREMENT INSIDE THE (LARGE) MASK: (see pictures)Height: 4 1/2" (inches)Width: 3 1/2" (inches)Great Mask.. at a Great Price on Amazon.. (however after all this comparison, i decided to go with this one rather than the 3M 6503QL because it fit a little better and has less detail on the front of it to catch and trap sawdust.)HOW DOES IT FIT.. Check your measurements. I tried several masks and sent back the ones that didn't fit right. (The third party ones "not" purchased from Amazon, i had to pay for shipping and even one from Amazon i had to pay for return shipping.) So buyer beware, try to get the right fit the first time. Also, buy a size up from the one you think. I tried to show photos with measurements to help. This is the mask i feel the most comfortable in. It's a LARGE, which fits up over the bridge of my nose nice and comfortably. 30 yrs of wearing masks and this is the best one ever. ## Frequently Bought Together - 3M Reusable Respirator Half Facepiece 7503, NIOSH, 3M Cool Flow Valve, Dual Airline Supplied Air Compatible, Integrated Dropdown Suspension, Bayonet Connections, For Chemical Handling, Painting, Large - 3M P100 Respirator Cartridge/Filter 60923, 1 Pair, NIOSH Approved, Helps Protect Against Organic Vapors, Acid Gases, and Particulates, Magenta, Yellow - 3M 2091 P100 Particulate Filter, 3 Pairs --- ## 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.co.uk/products/53651517-7503-reusable-half-face-mask-large](https://www.desertcart.co.uk/products/53651517-7503-reusable-half-face-mask-large) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-08-26*
