I have confirmed this to be 1,1-difluoroethane R-152a (HFC-152a) with zero ozone depletion potential and a global warming potential of 124 compared to R-134a with a GWP of 1430. The bitterant doesn't appear to be corrosive or affect it's performance as a refrigerant in my applications.

Dust-off has been around a long time. Quality is second to none. It gets in to the hard to reach crevices, especially on PC Boards. One great use is short bursts using the included long nozzle in to the lighting jack on an iPhone and/or iPads. Excellent on Keyboards too.

I have been using this product for years. Best prices are usually at the club stores for a set of 3 cans. When I saw this was available online for a 12 pack, I readily ordered. The savings over 4 3-packs was significant. The delivery was very prompt and tracking was accurate. Very satisfied with the whole transaction.

Convenient and Easy ordering process.

Excellent product. We use it to clean chainsaw when working in the woods and the air compressor is not available.

You cannot find this compressed air cheaper ANYWHERE. Sam's price on this throughout the years is awesome. And shipped to my door, don't have to stand in line. Thanks Sam's

I purchase this product all the time at Sams Club but needed more of it on hand and did not have the time to go back to city to get more. I purchased this on line at a great price and received it quickly and in great condition. I will definitely be using this service again.

The Dust-Off spray is an excellent cleaner for electronics. The only issue that I have is with your delivery carrier FedEx. They often pull onto my paver driveway with their 3-ton trucks instead of parking on the street like every other carrier does - UPS is great. A 3-ton truck onto the pavers will damage my driveway - leaking oil is impossible to clean off the pavers too. My neighbors are also "up in arms" about FedEx deliveries. Now the drivers aren't even making the deliveries to the front porch - This shipment was left on the side of the driveway and then the rain hit leaving a nice soggy package. The delivery before this one was left in plain site from the street in front of the garage door. The driver just had a few more steps to go to the front porch. Not acceptable to many of us. Please think about switching carriers to UPS.

Always expect this stuff to be in stock! And then it wasn't! I freaked! I use this product daily on my computer area, the car, the kitchen, and the washer/dryer areas. I have a dog that sheds like crazy so this is my go to to combat the hair and get it cleaned up faster than a brush.

The air duster cans had very very low pressure. I purchased 12 cans and have used 5 so far. All of them were completely low and didn’t dust Off my gadgets effectively at all.
