After look thru this, I think the number I referring to was aqi. I mistakenly took the pm2.5 as aqi. So got to switch the menu to aqi.
Tampines is missing from the map. This is the closest stn to my Punggol and sk.
There is a Longvale station, at the Southeastern corner of Bedok Reservoir. But i find the numbers (AQI) a bit on the high side, but nevermind you can just self-moderate if you wanna.
Past few days/current conditions seem pretty decent, but i guess nobody can fortell the future.

Just remember, AQI 150 is PSI 100 level.
AQI 170 is PSI 140 kinda equivalent.
AQI 185 is PSI 169.
Longvale did hit a peak of AQI 189 last Friday. And yeah if you are talking about your said smell test, there certain was a smell then.
I think if it is not like a fast interval LT2 workout with total volume of 40-60 mins , below AQI 185 (PSI 169) for this near real-time reference i think shd be fine for healthy pax without underlying medical conditions for other sessions that dont tax our breathing volume rate to super high. For eg, lower to mid zone 2.
Dont apply any health advisories to it, it's just a number at the moment for you to refer to and decide if the workout shd proceed.
