I think that people in Beijing and other Asian or American countries should stand up more often and force their governments to install filters on each fabric's smoke pipe and charge those who don't comply with a big fine. You can then open a petition that votes for using the money generated from that fine to for deploying fuel-less car alternatives… Come on, tell me you're helpless and dependent on your government and that your voice is not worth anything, that you can't change your country.. If you agree sir, I'm sorry. Sorry that you're not standing up for your rights. But then dear citizen, have the courage and inhale the smog in all it's glory and purity. The DIY Filter idea is great to have a transitional solution and I applaud the startup for this idea. But a government, a country, a company, or a stakeholder, none of them can make profit and money, when there are no trees to cut, no clean air to breathe, no healthy citizen to employ, no educated class to teach, no unpolluted earth for the seed and no will for change. Then you've created the perfect environment for a colony of sheep that follows a butcher who sells himself as a shepard.
