How Long Do Air Dusters Last? [Top 3 Air Dusters That Last Longer]

How long do air dusters last?

Think of air dusters as pressurized air sealed in a can or tin and forced out through a straw-like nozzle. An air duster is one of the most convenient ways to remove dust and dirt from computer keyboards and other electronics.

Their portability and mobility are the reasons they’re easy to use but are also the same reason you may be wondering just how long they’ll last.

A typical air duster is small and the tin can be held in the palm of one hand, so it’s okay to wonder if you’ll be able to use it for a long time, for multiple cleaning sessions.

It’s also important to respond to questions about the shelf life of an air duster and we’ll do justice to them in this post. Can you use an air duster more than once? How should you use them? Will an air duster last more than one use?

We’ll find out in a bit. We’ll also talk a bit about electric air dusters that became popular last year and how they’re changing the narrative of air duster use.

Do Air Dusters Expire?

Yes and No. Most canned air products or air dusters do not have a stated expiry date because manufacturers ordinarily do not expect anyone to have a can for more than 10 years, which is their average shelf life.

As long as the can is intact and the valve is undamaged, it should be able to sit pretty on a shelf for about 10 years.

Sometimes, depending on where it is stored or the quality of the container, you may find that the product has lost pressure, but the content itself may not have expired. Without pressure, it’ll be almost impossible to use an air duster.

This is why it’s a bit tough to answer the question. But it’s more correct to say No than to say Yes. As gases, propane and butane, which are ingredients of a typical air duster, do not have an expiry date.

When properly sealed, both will last beyond 10 years and may never go bad, unless kept in bad conditions or environment.

Remember that we can only say for sure when it is properly sealed. Once used for the first time, you’d need to secure the can properly for long-lasting usage.

How Long Does an Air Duster Last?

On the shelf, an air duster will last for 10 years or more. In terms of how long you’d use one, it depends on how you use it. It’s better you apply short bursts of 2-seconds air at the right angles than holding the trigger down continuously.

If you take the first approach, you can have such 2-second bursts in 200 places or more. However, holding it down may only last for 5-10 minutes. There’s a need to be careful and prudent when you use an air duster if you want it to last for long.

Be sure that the nozzle is not damaged or broken after every use in a bid to ensure it is well preserved and doesn’t leak out.

In recent times, we’ve also seen a number of brands introducing electric air dusters that use motors to collect and forcefully push air out to clean up those hidden spaces and remove dirt and dust.

When To Replace the Air Duster?

The simplest answer would be to replace the air duster when the can is empty. This can be after one use or several uses, depending on how you use it.

Also, if you haven’t used the air duster for many years and you find that the pressure is lost, you may also need to replace it.

The pressure is what gives it the force with which it comes out and blows dirt off the motherboard or keyboard, or whatever else you need to clean. Without the pressure, an air duster is as good as useless because there’s air but it cannot dust.

Also, you may have preserved the can in poor conditions, like in a warm environment or it may have been dented and leaked out. This is another factor that should trigger a replacement.

If you’re using an electric air duster, a power surge may damage the circuit, overheating may destroy the unit (especially if it’s a bad product), or the unit may simply just go bad over time. These factors present a good opportunity to replace the unit.

Important Tips To Improve the Lifespan of Air Dusters

There are a few steps to take if you wish to improve the lifespan of an air duster and keep it in good condition.

Tips to improve the lifespan of Air dusters
  • Preserve in a cool place, away from fire or heat.
  • Ensure no heavy item is placed on it as this can press the can and force the gas to come out.
  • Do not freeze, as this will cause the content inside to turn to ice and then possibly introduce water inside the can.
  • Keep the nozzle in good condition to avoid damaging or blocking the air pathway.

Top 3 Air Dusters with Best Lifespan

1. DOROBEEN Compressed Air Duster

Value for Money

As an electric air duster, you do not have to worry about the can getting empty or replacing it, because this product only requires charging and you can use it for 30 minutes before another round of charging is required. This makes it really long-lasting.

DOROBEEN is a trusted brand as far as electric air dusters are concerned and their products are quite durable, so expect this one to last for about 10 years of continuous use, as long as you’re using the right outlet.

With 41,000 RPM step-less speed, this unit released a maximum wind force of 2.47 OZ.

The 6,000 mAh rechargeable battery also makes it a very strong product as you can use it for 3 hours non-stop on its lowest speed.

Best for Features

ATEngeus is another pretty popular product for its resilience, durability and performance.

As an electric device, it also doesn’t require a mixture of gases, but uses an electric motor to pull in air and push it out with the kind of force that can blow dirt away from computer keyboards and other items.

This unit also has a very impressive lifespan, often reaching 8 years or more if used the right way. It is a very handy and functional unit, blowing at a force of 2.47 OZ. Its 41,000 RPM makes it the top choice on the market.

All of these qualities come along with its speed control, fast charging technology, and the fact that it can be charged in your car, with a computer or a regular outlet/extension.

3. Dust-off Falcon Compressed Gas Air Duster

Best Price

This is the only non-electric air duster that made it to our list of top 3 air dusters with a long lifespan.

Ordinarily, electric air dusters have an advantage over non-electric options because they do not run out, but this is one product that will stay preserved for as long as you need it to and as long as you store it properly and in the right conditions.

It is also pretty affordable as you can get some cans for a few bucks. If well sealed and there’re no leaks, this air duster can last for up to 10 years or even more. This largely depends on how frequently and generously you use it.

Another advantage is that it doesn’t need electricity to work so it can be used anywhere.


  • Very affordable.
  • No cost incurred on power.
  • Cannot be abused due to bitterant content.
  • Easy to use and handle.
  • Quieter than most units.


  • Bitterant may cause plaques on electronics.

Final Words:

Apparently, it may be wiser to go with electric air dusters because of the freedom they offer. They’re easy to use and you won’t have to worry about replacements too often.

What’s more, they’re likely not to be inhaled because they lack the components that give the feeling of euphoria. However, electric appliances cost money to run, and this is no exception.

Charging the battery will take some time, and some money out of your pocket as well. Hence, you may also want to consider some of the more common non-electric models.
