Last week, Saigon woke up to unhealthy air measuring 156 AQI at the US Consulate or roughly 65 micrograms. This gave me an opportunity to test my SmartAir Original DIY fan and HEPA filter in my other room. As you can see from the photos below, LaserEgg gave an AQI reading of 95 or 32 micrograms. The safe US levels are 12 micrograms so my room was 3 times above the safe level.
Hence, the SmartAir Original, with HEPA filter is a good DIY air purifier option. You will be available to buy them from the Southeast Asia Action for Clean Technology (SEAACT). We are currently working with SmartAir to organize their first workshop in Hanoi. This will be followed by Saigon and then Phnom Penh. Attendees will get an option to buy a DIY air purifier kit with HEPA fan at the workshops. More details will be provided at SEATAC’s website when it is launched this month. As of July, 2018, we were not able to register a company to sell HEPA filters in Vietnam. To stay under the radar, it is best to order the HEPA filters directly from SmartAir and build your DIY air purifier with the Senko model pictured above.
