I see, did not think they thought that point through.
Maybe worth mentioning is that I somehow filled in the flight out section even if I do not have a flight out of Thailand, so i just filled in as fly out date a year ahead and for the flight i gave: not known yet...
as we know now that was ok... at least for me...
Came in BKK yesterday, showed the QR code to the IO, which was enough, he did not check at all, could have shown him any QR code found randomly on the web... It would have been ok... They know this whole data collecting thing is nonsense...
Cheapest option is the Hatari one for just below 3000 Baht. Because I buy pm 2.5 fabric that I cut by myself to add it in front of the original Hatari filter, thus extending the life span of the Hatari filter by 500%.
Effectiveness is 100%, meassured with my pm 2.5 meter...
Just for our 60m2 lobby/living room we need 3 purifiers to get pm 2.5 to around 5 ppm on days when outside pm 2.5 exceeds 50 ppm...
I would never obstruct the airflow off the air conditioner in any way.
We are using the air purifiers from Hatari since I can easily mount a Filtrete in front of the original Hatari filter. Just takes a few minutes. This makes them very cheap to operate in the long run. The actual filter from Hatari I only replace every one or two years.
So in our 50 m² lobby we operate three such air purifiers and get down the AQI index down to about between 15 and 25. In my a bit less than 15 m² office I only operate one such purifier and I have an AQI index between zero and 12. The given values applied to outside AQI about 150.
But why in CW they do still accept 90 day report by Mail? And then not send back the confirmation despite provided envelope with stamp?
So after more than one month of sending in my 90 day report and nothing hearing back:
I went there by myself (had to go for EoS anyway). As proof that I did my part I presented the receipt from the post office which was accepted. I approached counter number 4. They wrote down my phone number which was called back 10 minutes later with the information that I could pick up the confirmation of my 90 day report right away. No need to wait in any queue or something like that. No need to show any documents. It seems they knew what they need to give me from the QR code on the post office receipt... The confirmation slip was dated back to July 25. So the confirmation slip was sitting on some desk for almost a month. They were to lazy to put it in the provided envelope to hand it to the postal service.
What was really annoying that they did not want to give an explanation why they do not send back the confirmation for the 90 day report. I really don't want to go there the next time I come back from overseas just to do the 90 day report.
Of course for the EoS they asked for a bank statement...
How to do a 90 day report online after coming back from another country? Not possible in my experience...
