Range of pollutants found in testing zone 

Pollutants	Value	Boundary condition
PM 2.5 µg/m3	222	The acceptable level of PM 2.5 is ≤ 30
PM 10 µg/m3	245	The acceptable level of PM 10 is ≤ 100
TVOC (ppm)	33456	Acceptable level is 160 i.e 0.3 mg/m3.
AQI (Index)	376	Which shows the tested zone is very poor according to AQI index

Table 1.1 Pollutants level

From table 1.1 it can be seen that in the tested zone PM 2.5 was very high and was constant throughout the measured time, the mass concentration was found to be 222 μg/m3 which is 7.4 times higher than the acceptable level. PM 10 was also crossing the acceptable limit with an average of 245 μg/m3, where the boundary lies below 100.  TVOC was found to be the highest source of pollution after PM 2.5, where the ppm spiked up higher up to 33456 ppm and the limit is only 160 ppm i.e. 0.3 mg/m3.  The Air Quality Index (AQI) was found to be 376 and the value lies in severe range, where AQI less than or equal to 50 is considered as good. 

Solution

Based on the area of the tested site, structure and the number of employees we propose a solution of recommending two units of “Aermax 500” and one unit of “CS250” (Ceiling suspended)  air cleaning systems in order to ensure clean air is distributed to the overall space and provide a safe environment for the students and employees. The ideal recommendation for the site would be to install two AerMax 500 and one CS250 given the location and pollution level around the site.

1. Range of pollutants found in testing zone, prior to the use of “Aermax 500”

From table 1.1 it can be seen that in the tested zone PM 2.5 was very high and was constant throughout the measured time, the mass concentration was found to be 221 µg/m3which is 7.3 times higher than the acceptable level. PM 10 was also crossing the acceptable limit with an average of 255 µg/m3, where the boundary lies below 100. TVOC was found to be the highest, where the ppm spiked up higher up to 1762 ppm and the limit is only 160 ppm i.e. 0.3 mg/m3 . The Air Quality Index (AQI) was found to be 378 and the value lies in severe, where AQI less than or equal to 50 is considered as good. 

Pollutants	Value	Boundary conditions
PM 2.5 µg/m3	221	The Good level of PM 2.5 is ≤ 30
PM 10 µg/m3	255	The acceptable level of PM 10 is ≤ 100
TVOC (ppm)	1762	Acceptable level is 160 i.e 0.3 mg/m3.
AQI (Index)	378	Which shows the tested zone is severe according to AQI index

1. Range of pollutants found in testing zone with the use of “Aermax 500”

After the installation of “Aermax 500” it was observed there was a moderate reduction of pollutant levels. From table 1.2 it is seen that the mass concentration of PM 2.5 was reduced from 221 µg/m3 to 46 µg/m3 which is an acceptable level. PM 10 was found to reduce from 255 µg/m3 to 53 µg/m3. The overall AQI after the performance of “Aermax 500” was below 80, which comes satisfactory category according to AQI index. The other pollutant such as CO2 did not vary because it depends on the number of occupants presented in the room.

PM 2.5 µg/m3	PM 2.5	46	PM 2.5 is satisfactory and was constant for a particular time.
PM 10 µg/m3	PM 10	53	The acceptable level of PM 10 is ≤ 100
TVOC (ppm)	TVOC	-	-µg/m3
AQI (Index)	AQI	76	Where the AQI gets satisfactory.
CO2  (PPM)	CO2	653	Moderate

Table 1.2 Pollutants level: With the use of “AERMAX 500” at speed “3”

  Fig 1: Comparison of AQI vs Time & PM 2.5 vs Time with use of “AerMax 500”

 

From fig 1. It is seen that PM 2.5 was in the range of above 221 and AQI was above 378 for the measured period of time without the use of “Aermax 500”, it is also seen that after the installation of “Aermax 500” the mass concentration reduced drastically when operated at speed - 6. 

When kept at speed -3 there was a slight increase in small peaks which were due to the outdoor air that comes from the exit door and then the reduction started again which was constant during the entire period of measurement. The reduction in pollutant level was maintained throughout the period of measurement by “Aermax 500” which made the environment safe and healthy throughout the day.

 Hence, during the use of “Aermax 500” it is recommended to start running the purifier at speed 6 for at least 30 minutes in order to get a quick reduction in pollutant level.
