You can also get blowers on Amazon. I got the MECO High Pressure Air Duster Blower Computer Cleaner Keyboard for Cleaning Dust, Hairs, Crumbs for Computer, Laptop, Tower Fans, Printer, Replaces Compressed Air Cans for $50. I take stuff out on my back porch, check the wind direction, and use it to blow off dust. It comes with various attachments to either concentrate or diffuse air flow. It’s very powerful - a video I saw where someone is lifting a smartphone is not fake - so you have to be careful using it. I’ve read a number of blog posts about cleaning computers and blowers are typically recommended over vacuuming.
