Fellowes Air Duster 350ml – Compressed Air Can, HFC Free, Dust Cleaner for PC, Keyboard, Printers & Electronic Devices, Home & Office

Great for laptop cleaning- take care to keep the bottle upright ... really... KEEP THE BOTTLE UPRIGHT - it will spray liquid otherwise (obviously not water, and the liquid evaporates instantly, but not ideal). Good pressure most of the time, it drop off with use as the bottle cools (obviously) so you're best using short bursts and then leaving it to come back up to room temperature (do not try and heat/warm it- just put it down for 5-10 minutes), that way you'll keep good pressure nearly all the way through the can. The supplied straw (mine had one) helps direct the air nicely and lets you do a good cleaning job.

This stuff is so useful. I had a problem with my PC and opened it up to find a thick layer of dust. Having used a vacuum and still having a problem I gave it a good blast with this stuff and I could suddenly see circuit boards and connections that were previously hidden. It's now clean and working and a good deal cooler for losing the dust. Since then I have cleaned the connections on several other pieces of electronics and everything is running more reliably. I'll need another can soon and this will likely be my choice. Good stuff.

For cleaning those "difficult areas to clean" - computer keyboards, computers, cameras etc this high pressured air cleaner is excellent. Recommended.

I have used this product before and it is really great for clearing the dust in computer cooling fans and for cleaning out all electrical items.

I bought this product to dust off my PC components and the clean the various keyboards and laptops around aswell. This can only lasted use between my PC and a set of keyboard and mice. To be fair, my PC has many drives and had 0 dust filters so alot was used. But I would say that a different product that I had bought before had lasted 2 times longer. The can is also not invertible, when inverted, a small spray of mist comes out which freezes anything it touches. If you read the back of the can, it states that it should be used in an upright position, so I'd suggest the seller clarify this rather than giving completely contradicting information. A small "straw" like tube is attached which fits snugly into the nozzle. This is the best part about this product as it makes it very easy to aim it at a small area and really increases the pressure, which made it perfect to declog my PC's heatsink. I do not recommend using this on any electronics that are still plugged in. If you do prepare for your device to be fryed. The liquid that sometimes comes out can easily short anything it touches so make sure any capacitors are drained and the item is unplugged before use.

Great product, really does the job. Really recommend

I bought this to help clean out my desktop computer and accessories, there was more than enough air to clean the whole computer, keyboard etc. with air to spare. There is good pressure in the can which is great for moving those tough bits of dust. My only comment is the can does get very cold and can cause condensation which would occasionally result in a small amount of water being sprayed out, nothing too major to be concerned about but did have me worried when cleaning around some high value items. I found keeping the can vertical stopped this issue.

Seems to deliver a reasonably powerful jet which can be directed. Managed to clear out a lot of dust from some fans attached to a water cooler. This didn't solve the problem, but at least showed that the water cooler had failed. Would buy again.
