This disposable N95 particulate respirator features the proprietary 3M™ Cool Flow™ Valve and helps provide comfortable, reliable worker respiratory protection. It is ideally suited for hot/dusty work settings that require long periods of wear.

 

3M™ Particulate Respirator 8511, N95 is a disposable particulate respirator that is designed to help provide reliable respiratory protection of at least 95 percent filtration efficiency against certain non-oil based particles. The respirator is designed for use for particles such as those from grinding, sanding, sweeping, sawing, bagging, or other dusty operations. This respirator can also help reduce inhalation exposures to certain airborne biological particles (examples: mold, Bacillus anthracis, Mycobacterium tuberculosis), but cannot eliminate the risk of contracting infection, illness, or disease. Soft inner material provides added comfort while the cup shape design makes the respirator spacious and durable. Braided headbands and an adjustable M-noseclip are designed to help enhance user comfort and increase wearability. The respirator incorporates 3M’s proprietary technology with advanced electrostatically charged microfiber filter media designed for ease of breathing. This respirator is compatible with a variety of protective eyewear and hearing protection.

Fitted with a 3M Cool Flow™ Exhalation Valve, this respirator is ideally suited for work situations involving heat, humidity, or long periods of wear. The proprietary 3M Cool Flow valve is designed to release hot, humid exhaled breath quickly, helping to prevent an unpleasant build up of heat inside the facepiece - a significant cause of discomfort to respirator wearers. The Cool Flow valve’s efficiency in keeping breathing cool and comfortable has been demonstrated through testing*: the atmosphere inside a respirator with a Cool Flow valve is on average 7.5°F cooler than the similar product without the valve. This makes Cool Flow valve respirators ideal for long periods of wear, especially where conditions are hot, humid or physically demanding. *Testing conducted in a 3M laboratory. Testing protocol, data generation and conclusions were reviewed and approved by an expert from The University of Minnesota. The testing performed by 3M is not a part of the testing and certification conducted by NIOSH.

This particulate respirator is NIOSH (National Institute for Occupational Safety and Health) approved for environments containing certain non-oil based particles and provides at least 95 percent filter efficiency.

Breathing hazardous particles can pose a risk to your health. NIOSH, a Federal government regulatory agency, has tested and approved the 3M Particulate Respirator 8511, which is designed to help reduce exposure to certain airborne particles. WARNING: These respirators help reduce exposures to certain airborne contaminants. Before use, the wearer must read and understand the User Instructions provided as a part of the product packaging. In the U.S., a written respiratory protection program must be implemented meeting all the requirements of OSHA 1910.134 including training, fit testing and medical evaluation. In Canada, CSA standards Z94.4 requirements must be met and/or requirements of the applicable jurisdiction, as appropriate. Misuse may result in sickness or death. For proper use, see package instructions, supervisor, or call 3M OH&ESD Technical Service in USA at 1-800-243-4630 and in Canada at 1-800-267-4414.

One of the Few Fuel Additives I Keep Buying
Color: Pack of 2
I've been using this product in my 2015 Ford F-150 for more than five years, and it's one of the few fuel additives that has earned a permanent spot in my maintenance routine. I originally started using it as preventive maintenance, but over time I noticed the engine seemed to run smoother after treatment. It's not the kind of product that suddenly turns your truck into a race car, but it has consistently done what I hoped it would do. I've purchased and used it multiple times over the years, which probably says more than anything else I could write. If a product doesn't work or isn't worth the money, I usually don't buy it again. This one keeps finding its way back into my shopping cart. I trust the product, I've had good results with it, and I think it's a reasonable value for the money. Based on my experience, I'll continue using it as part of my regular maintenance routine. If you believe in taking care of your vehicle before problems start, this has been a worthwhile purchase for me.

Mechanic Recommends Sea Foam -- Best Gas Treatment for All Engines
Color: Pack of 1
We have a small-engine mechanic who turned us onto SeaFoam motor treatment -- and against most gasoline preservatives and treatments. He said he'd drained, or seen inside, thousands of gasoline tanks, and the stuff sold as gasoline storage additives was often still there, sitting as gel on the bottom of the tank. Just gunk. He also said most brands of engine treatment weren't worth the money. However, he swore by SeaFoam, which I'd never tried at the time, and my experience since has proved him out. I've had many rough-running engines find their power and performance again, with nothing different, but a shot of SeaFoam in the gas tank (and the crankcase). We own a number of vehicles and equipment with small engines, from a compact backhoe, to a ride'em Husqvarna mower, weedwacker, chainsaw -- and on the larger size, a Honda SUV and Ford F150 pickup. All of them have benefited greatly from the regular use of SeaFoam. However, when we're running the road vehicles a lot, especially in the summer, we go through gas and don't necessarily add SeaFoam with every fill. Recently, the Ford began to run rough. It stalled as I pulled up to corners and lights. In the past, that would have meant a mechanic and an expensive tune-up. All I did was go for a fill-up, and started by adding a full can of SeaFoam. Problem solved, just like that. The Terramite (made in the USA) backhoe is not used a lot -- and as with most motors, that is a problem. It's bad for an engine not to run it -- and especially, in most cases, for it to sit with gas in the tank. The backhoe has a Kohler Command 25-horse gasoline engine that powers the hydraulics that run the wheels, steering, front-loader, and backhoe. I change the spark plugs each season, but it, like my Stihl chainsaw, and 6500 watt backup (gasoline) generator, and for that matter, all the small engines, can be hard to start after a hiatus. And even when they get going, they'll run rough. I used to drain the tanks frequently, then run them dry, then fill again before use, and hope for the best. But SeaFoam has changed all that. Throughout the summer, I can leave treated gas in the tank, and have little problems with starts or rough running. In the smaller equipment, I dose the gasoline with each fill (1 oz per gallon), as SeaFoam cleans both carburetors and full injection systems. It is good for gasoline and diesel engines. Added to your crankcase (1.5 oz per quart of oil), it cleans deposits and quiets noisy lifters. These days, most gasoline is mixed with ethanol and that's a bad thing for small engines. Ethanol goes hand in hand with water -- and as we all know, water in the gas is anathema to motors. Again, my small engine mechanic told me, 90% of the no-start problems he had to deal with were caused by ethanol-caused water in the fuel system. SeaFoam actually controls moisture and prevents this problem. It also de-ices and is anti-gel. In my opinion, when it comes to gasoline and diesel engines, large and small, SeaFoam is THE Silver Bullet. My equipment is often running, while my neighbors are running with theirs to the shop. I've told many about SeaFoam, but some people seem to want to do it the hard way. By the way, I also swear by PRI-G fuel additive for long-term gasoline storage. I keep 100 gallons of gas in tanks for emergency use. We are in a rural, wilderness area. I was introduced to that by survival expert, Steve Harris. He said he's had gasoline that was 10 years old still run equipment, because he'd added PRI-G to it (you can buy here on Amazon). Of course, you have to remember to add more PRI-G each year -- that's the catch. So our rule of thumb is, PRI-G for long term fuel storage -- and SeaFoam for month to month. Also -- this price is right! Of course, when you compare the cost of equipment breakdown, and having to take anything to a mechanic, this is almost free. However, apples to apples, this price is cheaper than Walmart -- and up to $4 cheaper per can than many auto supply and hardware stores. Can't say enough good things about this product! Highly recommended.

I swear by Seafoam, especially for small engines
Color: 3 Pack
I swear by Seafoam. It has really helped out my small engines, especially the 2 strokes and ones that sit around for long periods of time like my leaf blower and roto tiller. After I started adding Seafoam every time I get fuel I have had zero starting issues. They can sit all year and they will still start right up. In my car/trucks with higher miles I've used it to clean out the crankcase with great results. I add a can to the oil right before doing an oil change. I add a can then take a short drive(10 miles) to make sure the oil is up to operating temperature and change the oil once I get home. It does a good job cleaning any sludge out of the pan and the new oil stays looking fresh/clean way longer.

It's Sea Foam (but not green)
Color: 3 Pack
What is there to say? If you're buying Sea Foam, you know what it is and what it does, and you're probably going to continue buying it. It's great stuff.
