There were a couple of e-mail addresses at some of the sub sites: The first was the home page of the manufacturer of the filters, the second was what appears to be the distributor. Both are in Taiwan ROC

Again, I have never used these devices, and can't say anything for or against the quality or suitability of the product for use in the cars. I like the idea of adding extra filtering capacity for a wider range of pollutants (as done in current MBs). However, I would want to see some data showing that air flow had not been restricted over OEM filters, and some info showing the size particles and filtration efficiency of the particulate material, and adsorbtion/absorbtion efficiencies for various organics of the charcoal filters to see if they were really an improvement. Good luck, and let us know how it works if you proceed.
