You think? I'm ready for it. I just installed a 12 inch intake fan with an Hatari HEPA filter in one of my bathroom windows. I was a little kludgy since it's actually a high-volume exhaust fan which I reversed.

 

I can, by cracking the other bathroom window (which is normally sealed airtight), ventilate the bathroom with clean (PM 2.5 = 0.x) air or ventilate all my rooms by cracking a window on the opposite end of my one bedroom apartment from the bathroom. Air flow volume is not great with the HEPA filter in place, but the air is clean, at least.

 

The strategy is to not let raw (unfiltered) Bangkok air into my apartment, except through the two doors, which are kept open for for a matter of seconds.

 

Also have an Hitachi air purifier using the same filter (Hatari) in the bedroom where I spend most my time and have a portable, digital PM2.5 measurement device which appears to give accurate, reasonable readings. All my HEPA filters (there are 3) as well as my A/C evaporator are pre-filtered with a single layer of 3M FiltretéTM filter material.

 

I wear a two-layer PM2.5, one-way-valved mask whenever I'm outside my room in the air pollution of (ahem) Beautiful Bangkok.

You sound like fun....

Really? I'm been accused of that by someone else here recently. You quoted my post before I had finished editing it to add my out-in-Bangkok, two-layer, PM2.5 one-way-valved, filter mask. I'm a lot of fun. 😁

It's not bad / unsafe yet in BKK. But this week's levels definitely have been a jump up from the low/green/safe levels that have been prevalent the past few months.

 

We're still mostly in the yellow/moderate range, and not much yet into the orange/unhealthy for sensitive groups range. However, worse air is undoubtedly coming as we head toward the end of the calendar year and the start of the smog season.

By now, after several years experience with this, I'm well prepared:

--two functioning HEPA air purifiers at home (one for living room and the other for the main bedroom) with plenty of replacement filters in hand.

--supply of Filtrete sheets if needed to add to my regular air con filters.

--ample supply of N95 valved and unvalved masks for when having to go outside during the really bad times.

--Door and window jams at home already sealed with weather stripping to prevent bad air outside from leaking inside.

 

Get your stocks and supplies before the really bad air hits, because once that happens, all the stores here typically tend to sell out and these kinds of supplies/equipment become hard to find.

Usually September is the cleanest month. We could be in for the worst dry season ever.

 

The air in BKK usually doesn't start to get really bad until December, based on past seasons, and then that usually continues through March or April.  But there's usually an gradual upward slope of pollution levels in the run-up to December.

Best time to shop is November 11 (11/11), the Chinese online shopping day. Since Lazada is a part of Alibaba they drop their prices and shops are still well stocked with HEPA and 3M filters.

Bangkok air seems to be coming from Cambodia for the last week (at least storms are traveling East or North-East to West or South-West when I have checked).  So does not appear to be Indonesia burning related.

Not sure what's going on with the monthly sale dates on Lazada. I just bought a new mobile phone from them at a legitimate substantial discount, and it was part of a big "9/9" promotion they were having that day. The next day, the price of the same phone I bought had doubled back to its pre-9/9 sale price.  So it may be a recurring thing and not just an 11/11 only thing.

 

I noticed PowerBuy seems to be doing the same thing on the matching day/month dates....

Here's Berkeley Earth's current PM2.5 mapping for Asia. AFAIK, the white areas such as the PH means they don't have valid PM2.5 data for those areas.

yes , he made quite an understatement! 

at different times; I've been in BKK, Georgetown(lived 5 years), and Singapore... when the annual Indonesian rice fires were lit...
