And it's going to be much harder to get the dust back out than with a traditional fan due to the tight tolerances and enclosed design.

They seem to have forseen that problem: the air intake has a filter over it.

Even with a filter some dust is going to get in.

I believe the filter is incredibly fine because it can generate very high suction. I think they claim its dust proof.

And how does this filter not clog?

I don't know, but the filtration media that goes into consumer products that filter dust from indoor air last about 5 years before they need to be replaced. Many of those products use HEPA filters, which get all of the dust out of the air that passes through them, and even those last 5 years.

I have once serviced a PC that had been running for about 9 years as a fax receiver. The inside was literally like a block of dust. Every available space had dust in it with the consistency of a pillow.

I serviced it because the PC refused to boot :') Once I removed all the dust and reseated all the boards it worked fine for several more years :)

This. Sysadmins have air compressors for agood reason. A surprising proportion of the job is janitorial. Remember the famous bug that caused an error? Dust and cat hair are a much bigger problem than insects. Airflow obstructions are the number one killer of PCs and servers.

Those have massively greater surface area than this one. Have you seen how dusty it gets inside a laptop? This looks like it could choke in a month.
