> whether or not the MOF will also trap dust particles and other things This is the crux of the matter, yes. Of course you will need filtration to avoid clogging your MOF with sand and dust. Then you increase the power draw, having to push the air through a filter, and you have added a potentially expensive consumable. As TFA states, people have been making MOFs since the mid 90s. And people have been scrambling for applications since. The unanswered questions are, as always: Can they be made cheaply enough? Do they last long enough?
