DIY Air Purifier Bedroom Test (with real person)

At the request of a couple Expats from both Saigon and Hanoi, I decided to do a test of the DIY Air Purifier in my bedroom. My main air purifier since August, 2016, has been the BlueAir 203. BlueAir is a popular brand in Shanghai, China, so it was a good choice for me. When I moved back to Saigon, Vietnam, I brought my BlueAir with me.
 
I also started using the SmartAir Original fan and HEPA filter in Shanghai as well. I brought it to work, on occasions, but it ended up being my main air purifier on trips to Vietnam. I have a couple photos from Instagram where I used the Original DIY air purifier on a trip to Saigon. As you can tell, it worked very well in a hotel room roughly 40 square meters.

Start of Test

I will be using the same SmartAir Original fan and HEPA filter for this test. My bedroom is 20 square meters and has one CO2 ventilator between the room and kitchen area. I started the test around 10:45 am which is the normal time for me to turn my air purifier on after my session at the gym. The AQI in the bedroom was at 55 AQI which is not bad for sealed room.

The CO2 is a must have for bedrooms since the level of CO2 actual goes up while you sleep. It is also helpful in spreading clean air around the house.

Day readings

After running for one hour, my bedroom’s AQI just went down by 2 but 15 minutes later, it went to a healthy 37 AQI. The reason for this strange reading most likely the AirVisual Node was updating when I took this screenshot. Hence, it took about 75 minutes for the SmartAir DIY air purifier to get my bedroom to a healthy air quality. Not bad. Four hours later, the AQI dropped to 8 which is very good. Normally this is the range for my BlueAir 203. Even more surprising, when the air quality for Saigon got to 161 AQI, the SmartAir Original was able to maintain my bedroom at a healthy AQI.

Evening Readings

With the door closed, the SmartAir Original did very well maintaining the air quality in my bedroom. I normally go to sleep between 11:30 pm and midnight. I kept the SmartAir Original running all night. Normally the air conditioner is on at this time which helps clean the air as well, though just a bit.

Final Morning Readings

My final two readings in the morning. The AQI did go up a little but this is the norm even with my BlueAir 203. It is still at the healthy level. I ended my test at 9:10 am which is roughly the time I always turn my air purifiers off, unless the air is bad.

Final Thoughts

As usual, I am quite happy with the results of the DIY SmartAir Original. I will do another test with SEAACT’s DIY Air Purifier next week.

Until the next air purifier test, stay safe and breath in clean air.
