I think those small handvacs for cars and couches should be just fine. I agree with the article... I wouldn’t use the most powerful home vac system money can buy.
Never use a vacuum with computer components! Additionally, air from a compressor can contain water droplets and should not be used if the computer is going to be turned on right away. The vacuum, regardless of size, will generate a magnetic field due to the vortex of dry dust and sand. If an arc occurs, you will fry any component on that board.
Use the compressed air if you have to blow out the case. Filters are a great idea and very functional. Nylon is a great idea, I hadn't thought of that, but I would be cautious since nylon can be whipped into a magnetic field as well. I use plastic "wool" material that can easily be removed, cleaned, and dried with a few pats of a paper towel. Make sure you have an equal number of intake to exhaust fans. Include the fans in your power supply. Having one extra exhaust isn't a bad idea.
PCs are very much like automobiles. I had to relate it to my old man in car terms and he understood it that the processor was the engine, the RAM was the carbeurator, the hard disk was the fuel tank, etc. If we maintain our automobiles, we should look at computers are items that can use some TLC, esp. if you live in filth or smoke indoors.
