The Institute is situated near the National Capital Region of India where the AQI typically ranges between 150 and 250 during March-September, and between 400 to 500 (maximum on scale) during the months of October-February. The air quality in India‘s capital city, according to a WHO survey of 1,650 world cities, is the worst of any major city in the world. This can cause several ailments, ranging from premature birth to a decrease in lung immunity. Chronic headache, eye irritation, and skin irritation are common complaints due to the rising level of bad indoor quality in the capital city.
Business travelers started postponing meetings and events due to unacceptable air quality in the NCR area highlighted by the media.
Camfil’s scope included providing solutions to keep the PM2.5 levels less than 60 micrograms per cubic meter on a 24-hour mean. We carried out the site surveys detailing every air handling unit, evaluating the fresh air intake units, and return air paths. Existing non-graded local filters were replaced with Camfil ISO 16890 rated PM2.5 filters (Ecopleat F9) on each of the 20 AHU’s. New mainframes and universal frames were installed after dismantling the old frames. Besides, we added fresh air intake filters (ePM10 rated Dual 10 and frames) to check the ingress of polluted air through the fresh air inlet. The effectiveness of the reductions achieved were displayed by our air image sensor – one measuring the ambient air quality levels after the filtration treatment. Also, a Camfil digital screen showing the real-time AQI stats is being maintained at various parts of the building.
In addition to upgrading the air handling units and fresh air intake systems, the phase 2 part of the solutions included setting up of stand-alone air cleaners - City M and CC 2000 at various locations including the main training hall, the offices of executive directors, the waiting lounges and other training rooms. With the combination of AHU up-gradation with ISO 16890 rated filters and the stand-alone units, the resultant improvement achieved is 90% in the ambient air quality readings.
The quality of indoor air can be up to 50 times more polluted than the outdoor air. Indian capital region is witnessing harmful levels of air pollution that is affecting both work and life. IiPM has managed to improve the indoor ambient air quality by 90%.
