It would appear the air intake is on the bottom like the Mac Studio.
As someone who lives in a very dusty 150 year old house, My Mac Studio does not appreciate the air input being directly on the desk. It collects all the dust that lands anywhere near it.
I have a large levoit air filter running 24/7 in my office and still end up with this[1] regularly. I wish I could at least reasonably take the thing apart to clean it out.
In many big cities, getting a lot of dust is nearly out of your control, the only factor you can control is how often you gather it all up. I used to live practically next to a four-lane road when I was younger and even if you kept the windows closed, the dust would still creep in with every coming and going. If you ever opened a window, you'd know you'd need to vacuum soon.
Agree on dust removal. But if you have a constant source of pollutant input such as air pollution, dust or pollen, you want to be running a filter 24/7.
Large buildings don't run their HVACs in burst and then turn them off.
Many people are eager to plug in their air purifiers and get started, but they often miss the fine print about checking inside the unit. Leaving the plastic bag on the filter basically turns the purifier into a fan, without any actual filtering. I saw someone post that they ran theirs like that for months before realizing it—no air getting filtered the whole time! Your dust photo reminded me, so just wanted to mention it in case you hadn’t checked for the bag inside.
However, I don't see how this leads to more dust going into the computer compared to e.g. front-facing ventilation.
The dust landing on the desk next to the computer will slowly drift down onto the surface, passing right in front of any opening and being sucked into the device anyway.
