Magnetic air filters for the home, anyone? Its an untouched market! Not to mention magnetic filters for motorcyclists. Asia is full of motorcyclists who use dust masks. Adding a "magnetic filter", even one barely effective, might be very popular in Hanoi and Saigon, for example: https://www.google.com/search?q=motorcyclists+in+saigon+wearing+masks&client=opera&hs=fJq&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiDt_TFwbbUAhUKw4MKHSm2Dj0Q_AUICigB&biw=1105&bih=845 https://www.google.com/search?q=motorcyclists+in+saigon+wear... Finally, an application for old disk drive magnets!8-)): grind them up into coarse domain-sized grains at low temperature (so they don't lose their magnetism) and then toss them into the paper/fiber pulp mixture used to make masks. You should get a mask that filters the usual particles and also captures iron nanoparticles. Add a few billboards on major highways depicting nursing-home residents with Alzheimers' disease and saying "Don't end up like this!" and those masks will be flying off the shelves. Profit!

This sounds like a pretty brilliant idea to me, why isn't it already on the market? The article specifically calls the problematic particles "airborne iron-rich strongly magnetic combustion-derived nanoparticles (CDNPs)".

  It _has_ been discussed before: I just found a 2007 paper about dust problems in lunar living environments; the suggested solution is a magnetic air filter. Their solution is different of course (I was simply brainstorming about the powdered domains solution - there are many ways to magnetically filter particles from the air): "DUST MITIGATION: LUNAR AIR FILTRATION WITH A PERMANENT-MAGNET SYSTEM " http://www.lpi.usra.edu/meetings/lpsc2007/pdf/1654.pdf http://www.lpi.usra.edu/meetings/lpsc2007/pdf/1654.pdf There are probably many more such ideas published.
