In a recent study conducted by TERI to see the impact of Air Purifiers in improving indoor air quality with special focus on particulate matter (PM) and gaseous substances, it has been found that Sharp’s advanced Plasmacluster technology emits ions that destroy the chemical pollutants and neutralize harmful VOC and other toxic gases, thus purifying the air people breathe indoors. Sharp’s advanced Plasmacluster Ion technology works by generating Positive and Negative Ions by breaking water vapour in the atmosphere which through the fan mechanism is pushed out of the Purifier and spreads in the room. These Ions then react with the pathogens to create Water vapour which combines with the indoor atmosphere.
To assess the effectiveness of Sharp’s Air Purifiers, The Energy and Resources Institute (TERI) installed these air purifiers in three different types of locations in two major tropical cities in India, namely Bangalore and Delhi during the period Feb-Mar 2017 for continued monitoring & indoor air quality assessments.
Indoor air quality monitoring was performed in real world conditions and for the following parameters at all the selected locations with and without air purifier:-
- Respirable suspended particulate matter less than 10 μm (RSPM/PM10)
- Fine particulate matter less than 2.5 μm (PM 2.5)
- Fine particulate less than 1μm (PM 1)
- CO (Carbon monoxide)
- CO2 (Carbon dioxide)
- Ammonia (NH3)
- Nitrogen dioxide (NO2)
- Formaldehyde (HCHO)
GRIMM Aerosol Spectrometer was used for the measurement of PM10, PM2.5 and PM1 indoors. CO, CO2, Temperature and Relative Humidity (RH) were measured simultaneously using a portable Q-track monitor. For gaseous pollutants like NH3, NO2 and HCHO, air is allowed to bubble through a suitable absorbing solution using a handy sampler which was further analysed by wet chemical methods. The procedures followed were strictly in accordance with the guidelines laid down by Central Pollution Control Board (CPCB) and Bureau of Indian Standards (BIS). Sharp Air Purifier model FP-F40E was used in this study for impact evaluation. Indoor Air quality monitoring was carried for continuous 8 hours at each of the locations and after installation of air purifiers, monitoring was carried out for five time periods- 15 mins, 30 mins, 45 mins, 60 mins and 90 mins.
On analysing the data which was collected from same building type of both the locations, it was evident that the levels of PM10, PM2.5 & PM1 at all the locations throughout the study period was found to be following a decreasing trend as time elapses. This clearly indicates that irrespective of the building type, the performance of the air purifiers improves with time. The maximum reduction in all cases was observed when the air purifier runs for 90 mins. At most of the points, there was a continuous reduction in CO, CO2 (23-35%), NO2 (18%), HCHO (33%) with the use of air purifier.
Commenting on the study Mr. Shuvendu Mazumdar, National Manager, Air Purifier Business, Sharp Business Systems India Pvt. Ltd. said “Although there are several technologies which are being used for air purification like HEPA, Activated Carbon, UV, Negative Ion, Ozone but the time required in purification is counterproductive in some and the microbes that survive due to limited time of purification can become even more dangerous.” “Plasmacluster is Sharp’s original air disinfecting technology which is successful in suppressing the effects of airborne viruses, mould, allergens, dust mites, bacteria and removing odour to a large extent that traditional filters cannot”, he added.
The above study confirmed a drastic reduction in particulate matter levels (irrespective of size range) especially in finer particulates responsible for serious respiratory illness. Designed as an effective solution for the alarming pollution levels in the country, Sharp Air Purifiers now with a proven study can help to reduce airway inflammation among people with asthma and allergy thus making it a natural method of prevention from respiratory illnesses.
