Dental Aerosol Control  A 2010 peer-reviewed study in the British Dental Journal, found that the IQAir FlexVac extraoral air cleaning system significantly reduced potentially hazardous bioaerosols created during dental procedures. Classroom Air Pollution Control  A 2013 peer-reviewed US government study conducted by researchers from the South Coast Air Quality Management District (SCAQMD) published in the International Journal of Indoor Environment and Health found that IQAir stand-alone air purification and HVAC-based air purification was able to lower concentrations of ultrafine particles, fine particulate matter (PM2.5) and black carbon (BC) between 87% and 96%. In-Vehicle Air Pollution Control  A 2014 peer-reviewed passenger vehicle study funded by CARB (California Air Resources Board), conducted by researchers at the UCLA Fielding School of Public Health and published in Environmental Science & Technology found that an IQAir high-efficiency cabin air filtration was able to reduce ultra-fine particle exposure by 93% while keeping carbon dioxide concentrations in the range of 620-930 ppm. School Bus Air Pollution Control  A 2015 peer-reviewed study funded by CARB, conducted by researchers at the UCLA Fielding School of Public Health and published in Environmental Science & Technology, found that an IQAir school bus air purification system was able to reduce harmful air pollutants by 88 percent. In-home Air Pollution Control  A CARB-funded study by Lawrence Berkeley National Laboratory investigating reducing in-home exposure to air pollution found that IQAir MERV16 filtration on a supply system provided the greatest reductions in outdoor pollutant levels with indoor time-averaged concentrations that were lower than corresponding outdoor levels by 97– 98% for PM2.5, 97–99% for UFP, and at least 84–92% for BC and at least 97% for ozone. A two-year study conducted by UC Davis and funded by CARB focused on households with asthmatic children found that the use of high-efficiency filtration improves indoor air quality. Installation of IQAir stand-alone air cleaners and high-efficiency filters in central air conditioning systems were shown to improve indoor air quality across all particle size fractions, with the greatest improvement in the smaller size fractions. The study also found that while participants did not report reduced asthma symptoms, they did have fewer visits to doctor's offices and hospitals for asthma care and slept better if they also kept their bedroom door closed. Air Purifiers:   Air quality monitor:       Al Maqal  Al Maqal is a district of Basra, Iraq which lies in the north of the city centre, where the Shatt Al Arab Hotel, and Al-Maqal Port lie.
