Therefore, we suggest 3ESpace install larger industrial units like the Smart Air Blast purifiers in these rooms.Д«elow are room-by-room suggestions for purifier installation: Room For the larger rooms, small household purifiers like the Xiaomi would not be adequate to clean the entire space. We highly suggest that existing purifiers be turned on when the outdoor AQI level is above 100. We were surprised to find that although 3ESpace had 6 purifiers installed, not all of them were turned on. We recommend that affordable yet effective air purifiers like the Cannon be used to lower indoor PM2.5 levels. During this test, the Cannon reduced the roomвЂ™s PM2.5 concentration from 71Вµg/m 3 to 23Вµg/m 3, a reduction of almost 70% in just a 30 minute period.ДЇigure 1: PM2.5 levels when testing the Cannon Using the Smart Air Cannon purifier, we performed a simple 30 minute test in one of the 19m 2 meeting rooms. It is important that all the staff understand the benefits and importance of having an air purifier indoors, and turning it on whenever the AQI reaches вЂunhealthyвЂ™ levels. Furthermore, some of the staff did not believe that air purifiers do anything to reduce air pollution. We discussed purifier operation habits with the 3ESpace staff, and found that purifiers were only turned on when the pollution вЂlooks badвЂ™. The Xiaomi in question was in its вЂautoвЂ™ mode, which weвЂ™ve previously tested and found to be extremely ineffective. Unfortunately, during the time of our inspection, only one of the purifiers was turned on. Purifier habitsД¦ Xiaomi purifiers had been installed by the 3ESpace staff on the premises 5 months ago. See Figure 3 and Table 3 in Appendix 1 for more detailed results on the indoor air quality tests we performed.

Having windows open when purifiers are running drastically reduces their effectiveness at removing air pollution. However, the windows were open in one of the small incubators and rooms. The windows are well-sealed with a low risk of them leaking PM2.5 into the building. Inside, we used the Dylos DC1700 device to check for leaks around windows. From this, we can conclude that the premise is well ventilated and there is unlikely to be a large build up of VOCs or other gases inside. Using the AirVisual Node, we measured indoor COВ 2 levels, and found the average to be 578 (a typical outdoor CO 2 reading is around 400-600). The corresponding AQI is 158 (US), which coincides with an air quality level of вЂUnhealthyвЂ™. We tested the indoor air quality in 6 of the 3ESpace rooms, and the average indoor PM2.5 concentration was measured as 70 Вµg/m 3. However, we also noted that the 3ESpace building is generally surrounded by houses, which are unlikely to produce large sources of pollution. VOCs and PM2.5 from smokers outside the building main entrance.VOC and large dust from the construction works behind the building.We then made visual inspections of the surroundings and found the following possible sources of local pollution which could affect 3ESpaceвЂ™s indoor air quality: This AQI level corresponds to an вЂUnhealthyвЂ™ air quality level. The average outdoor PM2.5 concentration was 115 Вµg/m 3, which equates to an Air Quality Index (AQI) of 182 1. We used a Dylos DC1700 to measure the outdoor air quality along the front and sides of the 3ESpace building.
