buying & using can of compressed air

Is it worth it to buy a can of compressed air to clean the inside of a PC? How many uses does it take to finish the whole air content of this kind of can? How much should I pay to get one?

Would not it be the same just using a feather duster or a paintbrush which might be used for much longer without having to buy new cans of compressed air once they get finished?

Compressed air blows the dirt out of things like fans. You can use a fine bristle brush to remove heavy dirt, then blow it out with the air. It doesn't matter what brand you get, shop around for the best price. I used a 10 oz. can for about 4 computers already. Be careful with a brush or duster, you can dislodge wires etc.

I read that as "Buying a Used Can of Compressed Air" and LOL'd.

Canned air works fine (and is much better than a paint brush), but if you have many computers to clean, get an air compressor.

Please do not use a feather duster. The static electricity will kill your computer.

Actually those cans are not very eco friendly.

Consider an ESD safe vacuum. It is the best and most safe way.

Second but dangerous is low pressure/high volume compressed air. Compressed air can be a source of esd damage if you are not careful. Small parts and junk can be blown off into your eyes or breathed in. Do it outside and wear PPE.

Why did it take me over a year to phone in a problem to ATT?

A while back I bought a 15 gallon air tank at walmart. I'd fill it up at a gas station but it became increasingly hard to find one that was free and working. So I got a 1 gallon 100 psi pancake air compressor to fill up the tank.

I'd recommend you consider that. My son boiught the compressor I'm using so I don't know exactly how much it cost but harbor freight has some 3 gallon ones for $60. I think the air tank was about $25.

Besides not having to make special trips to the store to get cans of compressed air, you can use the air tank for any other air tools you may have or just fill up the occasional leaking tire.

I too use an air compressor. $129 thirty years ago. Along with a dust rag, paint brush, tooth brush and cotton swabs, you should be able to clean most of the dirt. Air alone will not bet off all the dust and grime. Machines near kitchens may be dripping grease and machines from smoke filled rooms are nauseating.

Could using a hair drier with a cold mode instead of "air compressor/can of compressed air" be considered a good option?

I doubt a hair dryer will be able to generate the air pressure necessary to blow the dust out.
