@TallGuyJohninBKK It is true what you say about HEPA. Please go to their website where you can find the CMU testing report.

In the report the averaged efficiency of the HEPA filter comes to 99.86%, this is still not 99.97%, although this is a good number which has been found by testing, therefore it can be seen that it is not just some marketing number but actual test results.

Hello,

I have developed a working prototype of a budget Air Purifier and portable AQI Monitor. I am currently looking for wholesalers and distributors in Thailand that can place big orders.

Any advice on where to start? Is there a website where I can list my product? An event where these companies gather? How efficient it is to send emails in English language to these potential distributors? Is it better to call or just go in person?

Thank you
