Bangkok Air Pollution

Recommended Posts

I don't need a SNDWAY.

I just look out of my window (high floor) and visibility has never been so good since the beginning of December.

 

Just to make sure its true i verify with the website and yes, the reality isn't fake! The internet says it.

You verified your window's (high floor) visibility on a website?! Which website was that? :stoner:

You might want to close that window as the recent high PM2.5 pollution level seems to be causing you some false euphoria.

We've been in the green zone for almost a week now here in Pattaya. From 15 to 35 PM 2.5. Very happy right now.

The air in BKK is medium yellow moderate right now, and has been either green or low to moderate yellow for most of the past week -- a time that usually is BKK's worst smog season with normal levels this time of year routinely in the red unhealthy levels.

 

The most interesting issue about this is why the sudden and unlikely change. Could be partly weather related with the pickup in breezes lately. But I also wonder if the powers that be finally felt enough heat to do something (other than the useless fire hose water spraying) to cut down on pollution emissions.

Got an email from Big C Online lately advertising this PM2.5 sensor. Don't know anything about it, never seen it before. Lately, a lot of the Thai retailers have been pushing smog related products... When there's a buck to be made....

Power Buy's also been getting into the act on this. The email I received from them today advertises Samsung inverter air cons claiming to filter PM2.5 and an electric clothes dryer claiming to remove "pollutants" from clothes because they're not going to be hung outside....  Hmmmm....

 

The air con thing is interesting though. I have no idea what kind of filtration these kinds of units provide and what's required to maintain them. But it's long occurred to me, with air cons already running a lot here in hot climates, why couldn't HEPA filter technology be incorporated into regular air cons vs. having to run and pay for a second, separate air purifier unit.

The technology looks extremely unconvincing to me. How does this normal looking filter manage to get the pm2.5 to stick to it?

Check this out........seems like one can buy PM 2.5 filters for existing aircon units:

That's now, 80 I can live with (would prefer the 30-40 of the last few days), was back up to 165 here at around 3pm though with readings on Air Visual from Soi 20 / 22, like I say, didn't last long 😞.  Traffic's back I guess.  Be interesting to see how the remainder of the month plays out.

Not sure about the reading you're citing... I don't think it is/was reflective of the day at large.

 

For example, when I look at the hourly history of Air Visual's reporting for Pathum Wan for today, I see nothing but yellow moderate readings for the entire day. Same basic results for Chula Hospital and the NIST sensors around Asoke.

The image below likewise shows the hourly readings for Chula being entirely yellow for the entire day Thursday, and for most of Wednesday as well.

I believe, that's pretty much the same as the red Filtrete sheets sold in the stores here, which can be placed over traditional air con filters. But they provide nowhere near HEPA filtering capability.

 

In fact, interestingly, if you look at the product details for the item you've linked to above, it says the following:

 

Quote

Proven to capture 83% PM2.5 from indoor air in just one hour of use.

Quote

Designed to cover around 80% surface of existing mesh of most models of ACs (to balance air flow and PM2.5 capture rate) – you may cut it smaller as per your AC size if you feel it is reducing air flow by large extent

 

The official HEPA standard, by comparison, is removing at least 99.97% of airborne particles 0.3 micrometers (µm) in diameter.

Samsung appears to be claiming 99% filtration capability of PM2.5 within 100 minutes of operation in a 30 sq meter room.

 

Quote

Reduce small dust 
Over 99% 
Ultra Wide PM2.5 Filter 
 
Tiny particles in the air may creep into your lungs. PM2.5 Filter helps keep the air clean. By trapping small dust particles up to 99% in 100 minutes * It also covers 100% of the inlet Therefore filtering all air entering the machine completely
