Compressed Air Duster For Computers

of November 2023

Whether you use a desktop or laptop computer, they use one or more fans to dissipate the heat that builds up inside around the CPU and on the graphics card. Fans draw cool air into the computer from the outside, but they’ll bring in dust along with it. Dust that accumulates around the fan and inside the computer chassis will cause the fan to slow down, and cause heat to build up inside. In fact, dust is the main reason for computers to fail–and all of the software upgrades in the world won’t be able to help. It’s imperative to remove the dust regularly for your computer to function properly. And a compressed air duster can help with that.

We’ll see that there are two main types of compressed air dusters: there are disposable cans of compressed air and battery-powered devices with a motor that propels air at a tremendous speed to blast away any dust. They’re sure to knock out any dust from your computer’s fans. And they can be used to clean your computer keyboard, mouse, game console, and much more! A compressed air duster can extend your computer’s life, and also improve its performance as well!

Why should I use a compressed air duster?

Compressed air dusters are a great way to clean hard-to-reach areas and remove dust and debris from sensitive equipment. Dust in your computer can make it run slower, and may even shorten its lifetime. And besides using compressed air to clean out your computer’s fans and motherboard, you can also use them to inflate an inflatable kayak or other flotation devices. Some even recommend using it to provide more air to a barbecue grill, to make the charcoal burn more brightly!

Looking over the Best Reviews Guide of the best compressed air dusters, we see a number of options available:

• Cans of compressed air: There are cans of pressurized air which come with a detachable nozzle to get into tight areas, like in between the keys on your keyboard. An example is the iDuster Compressed Air Duster.

• Battery-powered: There are also compressed air dusters that are battery-powered. For example, the PGroup Compressed Air Duster charges up using a USB cable and can work for over 20 minutes on a single charge. It comes with five different types of nozzles, to either blow a concentrated stream of air or over a wider area. It can even be used to inflate a kayak or balloons!

Here are some of the impressions of customers regarding their choice of compressed air dusters:

• Advantages of battery-powered compressed air dusters: Buying cans of compressed air may be a better option if you only intend to use them to clean out your computer once in a while. But, if intend to service people’s computers, or if you will use compressed air for other cleaning jobs, you’ll prefer the battery-operated compressed air gadget.

  • More economical: The extra cost of the device will pay for itself, instead of having to buy cans of compressed air every so often.

  • Safer: There is also less of a risk of damaging your electronics from condensation or injuring yourself from the refrigerant in a can.

  • Versatile: A can of compressed air can blow away dust efficiently But a battery-powered duster can have other functions. We already mentioned the various nozzles available. And there are compressed air dusters that can also vacuum for you, such as the PeroBuno Compressed Air Duster.

• Read the instructions: Some customers who used the canned compressed air didn’t read the instructions sufficiently. As a result, they didn’t hold the can upright, and the liquid propane in the can oozed out on their keyboard and froze. So, make sure that you 1) keep the can upright, and 2) don’t shake it before use!

Here are some tips and essential features to look for when selecting a compressed air duster:

• Don’t shake the can: With most aerosol cans, like room deodorizer or antiperspirant spray, you shake the can before spraying it. This is because these cans have a fragrant product, plus a propellant. In order to get the fragrance out properly, it has to mix with the propellant. Otherwise, without any propellant, there will just be a fragrant liquid inside the can. However, with compressed air, if you shake or tilt the can, it can make the refrigerant inside the can come out in a liquid form instead of as a vapor. This can cause “freezer burn” or frostbite. So, it’s best to let the can settle before spraying.

• Dangers of cans of compressed air: Although it’s called “compressed air”, it’s not really the same thing as the air that we breathe, just in a can under pressure. For example, the product Dust-Off has a refrigerant-based propellant, difluoroethane. Others may use butane or tetrafluoroethane. But trying to inhale the product can produce a euphoric “high”, which can lead to delusions, heart irregularities, or even paralysis. So it’s highly advised to use the cans of compressed air solely for their intended purpose: to blow away debris. Also, they add a bitterant to the canned compressed air, to prevent any substance abuse.

• Different nozzles: The Heyjar Compressed Air Duster comes with 4 different nozzles. The inflator nozzle is suitable for inflating a soccer ball or swimming ring. The wide nozzle can be used for inflating air mattresses. The long nozzle is for getting inside electronic devices. There is also a nozzle with a brush at the end, so that you can brush out dust before blasting it away with compressed air. (The PeroBuno Air Blower allows you to attach the brush to any of their nozzles, which gives you greater versatility.)

• LED light: Another nice feature of the Heyjar Compressed Air Duster is that it has an LED light. That way, you can illuminate the inside of the computer while you’re cleaning it. That way, you can make sure that you got out all of the dust.

Final Verdict

We studied some of the features of compressed air dusters, noting the advantages of canned compressed air, and battery-powered compressed air dusters. It’s important to clean out your computer’s power supply and CPU fan so that these parts don’t clog up with dust and overheat. A compressed air duster can help with that. And they can blast out dust and debris from your computer keyboard or other sensitive electronics. All told, it’s a worthwhile investment to protect delicate devices that are important to you!
