"...a light blast," Rev!

Always consider moderation... especially here at HF! :lol:

Almost all computer devices have electric fans, many of them unfiltered. :(

It's when they are not cleaned with a light blast of air or propellant, and dust gets thick, that it becomes a problem....

Sorry to add to your confusion, but all synthetic thread and all synthetic fabrics are polymer fiber products.

You don't use cotton, do you? :scared:

I would like to suggest a change to the term "thread injector"... it's not quite manly enough.

I prefer "polymer fiber injector!" :thumbup:
