SoilSpoil Posted November 15, 2018 Share Posted November 15, 2018 FIRMS Fire map shows a lot of big fires north of Bangkok. As no government dares to upset farmers just before an election, it's time to blame Bangkok's traffic problems again. Link to comment Share on other sites More sharing options...
chubby Posted November 19, 2018 Share Posted November 19, 2018 Today Monday starting @ 137 Orange, brought up this topic with some expat friends over weekend they said, they don't like AC and would have to use it if they sealed their apartments adequately of all drafts I wonder , therefore if there is any point in closing my large sliding glass balcony door on an "Orange" day if I have no Air Filter ? I saw the Xiamo Purifier along with their other products in a glass case inside the Asoke BTS interestingly and I saw a guy walking out of Robinsons with an N95 Mask on (1st one I've seen since looking for one here ) Would it make any sense to buy a air purifier in the US and bring it here to Bangkok, maybe a wider choice and cheaper price ?

balo Posted November 19, 2018 Share Posted November 19, 2018 My meter shows around 50 today or 136 AQI, in Pattaya. It's a clear sky but the pollution is worse now , I can feel it in my throat. So will wear a mask today. Link to comment Share on other sites More sharing options...
TonyClifton Posted November 19, 2018 Share Posted November 19, 2018 So many stupid and non-factual replies. If you aren't blind, then look out your window. If you can only see 1.5 miles then assume the pollution is high. I run two very good air filters 24/7 along with air conditioning. I breathe clean air.

I have a very good, large capacity Honeywell HEPA purifier I brought from the U.S. many years ago and have used all along. But, as noted, using it or anything similar from the U.S. requires also having a step down transformer to convert the local 220 electricity into U.S. 110V. With such a transformer, a U.S. sourced air purifier can work perfectly fine here. And step down transformers are available here locally from electronics shops like Amorn in FortuneTown. HEPA air purifiers tend to be overpriced here compared to what you'd pay in the U.S. for comparable models. But at the same time, air purifiers and transformers tend to be large / bulky / heavy items that don't go particular well in the typical airline check-in suitcase. In my case, the purifier and transformer arrived as part of a relocation shipping container shipment. Link to comment Share on other sites More sharing options...

On the recent 11.11 sale on Lazada, the official Xiaomi shop was selling its 2s purifier for under 4000 baht, which is comparable to its price in China. They were also selling the Pro model, which is for rooms up to 60 square metres, for under 7000. If you don't have a room larger than that, there's no point importing from the US. Even if you do, running two purifiers would be effective. Link to comment Share on other sites More sharing options...
kekalot Posted November 20, 2018 Share Posted November 20, 2018 I'd assume that getting your hands on US sourced purifiers filters might be a bit of a headache as well.. unless of course you buy a bunch of them along with it. that is only if they would even work down there, would need a voltage switching power brick input Link to comment Share on other sites More sharing options...
oval Posted November 21, 2018 Share Posted November 21, 2018 Moved to a new condo on a higher floor and this morning the air looked shocking from my windows. Re. air purifiers I decided to go the cheap DIY way so bought a bunch of 3M Filtrete from Central Chidlom and taped it over the filters of the 3 AC units in my place. I don't have a air quality monitor so I don't know how well they are actually working, but the Filtrete has a solid reputation and is already going a little grey. Give me the wet season over the cool season any day. I'd rather be getting wet than breathing the crap that's in the air now. Link to comment Share on other sites More sharing options...
JimShorts Posted November 21, 2018 Author Share Posted November 21, 2018 (edited) A good quality air purifier from the US will not be any better then a good quality air purifier purchased here in Thailand. As noted it will also require a step down converter and may be a hassle getting replacement filters for it. Many top brands are available here in Thailand, such as Blueair. If you buy them during sales the prices are not too bad. Personally, I really like the Thai brand Bwell. Used by many hospitals and government agencies here in Thailand. Very reasonably priced. They have HEPA filters that filter both air pullution as well as VOC. The default Blueair filters do not filter VOC and the upgrade Blueair filters are twice the cost of the standard ones. You can find more info and order Bwell from their website here: http://en.bwell-inter.com/ I have a few Blueair as well as a few Bwell purifiers. I also have two different brands of monitors. The Bwells work just as well as the Blueair filters, if not better. The Bwells are much less expensive to buy and the replacement filters are way less expensive. They also make small portable units which you can use when traveling or in the car. If I could do it over, I would have only purchased Bwells and saved myself a lot of money. Actually the next time I need to replace my Blueair filters, which cost more then a brand new Bwell purifier, I may just sell the Blueairs and replace with Bwells. (Hehe I sound like a Bwell sales person. Really I am just trying to share the information that others may find useful) Edited November 21, 2018 by JimShorts 2 Link to comment Share on other sites More sharing options...

TallGuyJohninBKK Posted December 19, 2018 Share Posted December 19, 2018 (edited) W-T-F???? I thought my air purifier at home had stopped working properly, when my indoor sensor levels started climbing unusually high with the purifier running on medium... But no, it's the air outside, not the purifier. This is one of the highest PM2.5 readings I've seen for BKK in the year that I've had sensors and purifiers at home. This began Weds night and continued into Thurs morning. Is there some big fire somewhere or something?

balo Posted December 21, 2018 Share Posted December 21, 2018 It's been really bad here in Pattaya as well , I measure 120 ++ which is the highest I have seen since I bought my AQI reader.

If the coming smog season is anything like last year in BKK, the bad air won't be continuous, but there will be frequent and extended spikes of heavy air pollution depending on the weather conditions, as Thais upcountry and others elsewhere engage is their seasonal burning rituals, despite repeated government pledges to put a stop to them. Thailand and its SE Asian neighbors literally on fire. Link to comment Share on other sites More sharing options...

Does anyone know are the yearly spikes related to crop burning, or wildfires? Cool stuff. Thanks for sharing that site. WRI uses NASA Fire Information for Resource Management Sytem (FIRMS) near real time (NRT) active fire data from the MODIS and VIIRS satellites to map fire locations. The sensors on these satellites detect the heat signatures of fires from the infrared spectral band. When a fire is detected, the system indicates the area where the fire occurred with an “alert.” Because each satellite orbits the earth twice per day, these alerts can be provided in near-real time. Fire alerts are posted on the NASA FIRMS website within 3 hours of detection by the satellite. The accuracy of fire detection has improved greatly since fire detection systems were first developed for the MODIS satellites. Fire data from the MODIS satellite are approximately 1km resolution and VIIRS satellite data has a resolution of 375m. Today, the rate of false positives is 1/10 to 1/1000 what it was under earlier systems first developed in the early 2000s. The algorithm used to detect fires includes steps to eliminate sources of false positives from sun glint, water glint, hot desert environments and others. When the system does not have enough information to detect a fire conclusively, the fire alert is discarded. In general, night observations have higher accuracy than daytime observations. Desert ecosystems have the highest rate of false positives. Many papers have been published to validate the NASA MODIS active fire alerts for use in various applications.
