Good but no data of its effectiveness
This is a good idea, i.e. microfiber, or micro-organic cotton.<br />But the manufacturer lists no tests as to its effectiveness, as well as no lab reports, or how many microns it can filter.<br />It may as well endanger the health than help people as its use may not be either for chemical sensitivities since a mere cloth material does not seem to filter gases, or harmful smog substances.<br />It may filter up to dust, pollen, etc.<br />For the serious commuter, they should get a real smog mask, or gas mask specific for volatile gases if they job necessitates this.<br />They should at least put specific info as to the microns it can filter. On the other hand, the comsumer should stay away from using it in harmful environments.
