Great! Now it’s time to figure out some other way to get dust and grime out of your electronics or other devices. So you’ve arrived at the idea that shipping yourself compressed refrigerants is not a sustainable practice. Your Non-Canned Alternatives: Easy, Medium, and Intense Inhaled dusting gases displace oxygen in the lungs, remove carbon dioxide from the blood, and can cause heart irregularities or failure, even after one session. But even one huffing session with canned air can lead to death, and 100-200 people die each year from inhalant abuse. Canned air may be abused by up to 10 percent of Americans at some point in their lives. You know you’re in a dark place when you find a Snopes post that checks out true. Having read far too many posts about using canned air to clean electronics, it seems like spraying freezing-cold refrigerants on a circuit board likely won’t short the components, because it evaporates so quickly and is not full of circuit-shorting impurities like water. So to be fair, all you have to worry about is global warming, frostbite, fire hazards, and its deadly properties as an abused inhalant. Some gas used in canned air is highly flammable. The can itself very rapidly cools, such that you can receive cold burns on your hand from holding it too long. If it touches your skin, you can get frostbite. The liquids will rapidly cool anything they land on. As noted in that explanation, spraying a gas duster any way but straightforward and upright can result in dispensing the liquids inside-I’ve done this nearly every time I’ve used it. If you’re using canned air with butane inside, that’s both an environmental nightmare and highly flammable, so please dispose of that responsibly.Ĭanned air works through a useful, and honestly fascinating quirk of thermodynamics, explained in a quick video by Minute Physics. Cans containing tetrafluoroethane are far worse, with a GWP of 1,300, and lasting 14 years in the environment. It has a Global Warming Potential (GWP) of 140, according to the EPA, meaning one pound of difluoroethane is the equivalent of 140 pounds of carbon dioxide when it comes to global warming.
While not an ozone-depleting gas, difluoroethane is a greenhouse gas. Take a look at the contents of a can of common gas duster, like Dust Off. Why You Should Ditch Canned Air Iimage by Drb400atx/Wikimedia And you can kick your habit at a few different price points and commitment levels. But neither are ceramic dishes and reusable totes instead of styrofoam and plastic grocery bags. I’ll warn you up front: The alternatives to gas dusters are not as convenient as buying a cheap, disposable product. Whatever you call it, spray dusters are bad for the environment, less agile than hand tools, and deadly if abused. But you shouldn’t use it.Īllow me to suggest some alternatives to canned air, which, for starters, is not canned air, but compressed refrigerant.
It seems like the right tool for the job.
It’s easy to find at big-box stores or online, it’s relatively cheap (if you don’t think about paying for air), and it moves dust. Canned air, or gas duster, is what you probably reach for when there’s hard-to-reach gunk inside your gear.
