Under $20 for a 10-pack. Buy a box and stash extras in your bag to give away to people.

They concentrate the heat around your mouth, and don't direct your breathing like a respirator. And, they look silly. An RZ mask forms to the face better and directs airflow MUCH better. Gas Masks are not for the pussies! But they work! Shemaghs are for trendy fucks who believe everything their told. AGAIN! It's really a personal choice!junglesmacks wrote:

Cause they really kicked ass!!!!!!
The one way valve doesn't let heat build around your mouth in the least and does direct your breathing directly out the vent. You don't even feel like you're wearing a mask breath wise.TomServo wrote:They concentrate the heat around your mouth, and don't direct your breathing like a respirator.

DUDE! I had my 7-up bottle brownbagged, when I was too sick to drink Malt Liquor! Reputation, Reputation, Repetition! It really is a PERSONAL choice! I happen to LOVE gas masks! I've passed out in 6 hour dust storms in a gas mask...worked GREAT! And, having had to use these devices in the professional realm, I prefer the expensive ones.junglesmacks wrote:The one way valve doesn't let heat build around your mouth in the least and does direct your breathing directly out the vent.

That's a pretty strong statement.junglesmacks wrote:Certified against mineral dust with complete and total filtration...
Searching now. Here's the manufacturers info page on it.Canoe wrote:That's a pretty strong statement.junglesmacks wrote:Certified against mineral dust with complete and total filtration...
Where's the data on what percentage of what size of particle it filters?
Savannah wrote:It sounds freaky & wrong, so you need to do it.
On surgical masks:
Surgical masks are not designed for use as particulate respirators and do not provide as much respiratory protection as an N95 respirator. Surgical masks provide barrier protection against droplets including large respiratory particles. Most surgical masks do not effectively filter small particles from the air and do not prevent leakage around the edge of the mask when the user inhales.
Collection efficiency of surgical mask filters can range from less than 10% to nearly 90% for different manufacturers’ masks when measured using the test parameters for NIOSH certification.
The FDA, in part, accepts the NIOSH filter efficiency and breathing resistance test results as exceeding the usual surgical mask requirements.
Given the particle size distribution of Black Rock Playa soils:on NIOSH-Approved Particulate Filtering Facepiece Respirators:
Whether the goal is to prevent the outward escape of user-generated aerosols or the inward transport of hazardous airborne particles, there are two important aspects of performance. First, the filter must be able to capture the full range of hazardous particles, typically within a wide range of sizes (<1 to >100 µm) over a range of airflow (approximately 10 to 100 L/min). Second, leakage must be prevented at the boundary of the facepiece and the face.
the most important aspect of a NIOSH-certified respirator’s performance will be how well it fits to the face and minimizes the degree of leakage around the facepiece. This must be measured for each individual and their selected respirator.
It is more difficult to fit a half-facepiece respirator (one that covers the mouth and nose only) than a full-facepiece respirator (one that also covers the eyes).
all particulate filters used in NIOSH-certified respirators, including N95s, are designed and engineered to provide very high levels of particle collection efficiencies
perhaps the most misunderstood aspect of filter performance and bears repeating. Filters do NOT act as sieves. One of the best tests of a filter’s performance involves measuring particle collection at its most penetrating particle size, which ensures better performance for larger and smaller particles. Further, the filter’s collection efficiency is a function of the size of the particles, and is not dependent on whether they are bioaerosols or inert particles.
Whoever wrote that is pretty silly. It's going to depend on things like particle size, and I wouldn't be surprised if things like how hard you're breathing made a difference...Canoe wrote:I'd read before that the N95 rating meant that it only filtered 95% of particles.
So go read the definition of N95 if you don't believe the copy and paste I did of it.theCryptofishist wrote:Whoever wrote that is pretty silly.

N95 is a NIOSH standard.theCryptofishist wrote:Who said it? Three M? OSHA? Wikipedia? Because everything on the internet is 100% accurate.
Sorry, I believe you found it on the internet, I just find that unless it's something like "95% of particles size n at suction strength y" I just wont believe it.
Yes, if N95 and a half-mask is enough for one's needs, it sure looks like a good choice. Accommodation for sealing well with eyeglasses too.junglesmacks wrote:Thanks for digging that up, Canoe. Yeah.. the embedded picture is that of the 9211. There is now the "9211+" which is further enhanced with comfort/design features.
I wish there was a picture of the inside of it to show the foam seals. It's way more than it looks from the front..

Yeah. It's a bit of a nuke, but to provide enough of a core of good info so people can decide if they have enough info to choose with or if they need to find out more...theCryptofishist wrote:Ah. TLDR. I just reacted to the second line. Sorry
Not sure if I'm allowed to post the link to these, but if you search for "ATV Tek Pro Series Rider Dust Mask" they are easy enough to find. I did the XL, user feedback was that the mediums are too small for most ppl. There's a fabric discounter I was alerted to on reddit's burning man group yesterday, fantastic deals. ok I've rambled enough about bm items on sale 
"Playalung" dust masks is just someone trying to capitalize off of TTITD by associating their name with the Respro brand dust masks and reslling them for jacked prices next to burny looking people complete with playa chicken feathers in their hair. Google the true company name and you'll find all kinds of discussion on them both on eplaya and off.Earthwalker wrote:Apologize if I missed it, but I read the entire thread and didn't see any feedback on the original topic: Playa Lung Dust Masks.
