That is because I was using a VPN at the time of my previous 2 posts. now you should see me in Singapore now. Nowadays IP address does not tell much.
The recent haze got my attention to air quality, did some research online, and IQair seems to be the best. I could not find any info on their web site regarding where to buy those in Singapore, that was why I have to ask someone in the forum. Again, no funny business here.
