We have an office in Singapore, here's one of our colleagues report alongside with this image.

Singapore at 8.30 this morning, as Ali and Michael struggle to work through what appears to be Dickensian fog. The PSI (Pollution Standard Index) hit 321 which is well within ‘Hazardous’ levels, as Sumatra conducts its annual burning to clear land for palm oil, killing wildlife in the process. Reports say that nearly a 3rd of the only 200 remaining Sumatran Orangutan have already died as a result of this year’s burning. The whole island is wreathed in smoke, everything smells, inside and out, some people are wearing masks in their offices... a far cry from Leeds.

I have to fly to Singapore next week. I can bring some masks if you want. Can someone with familiarity with 3M products recommend which of these might be more suitable? http://www.3mdelivery.com/cid-85-name-r-no-1.html

There's a crowdsourced list of shops selling N95 masks on Google Docs: https://docs.google.com/spreadsheet/lv?key=0AuLloIXRvoaOdGxJ...

Look for NTUC Unity. There are many branches around the island.
