It focuses on air cleaners for residential use; it does not address air cleaners used in large or commercial structures such as office buildings, schools, large apartment buildings, or public buildings. It should be particularly useful to residential housing design professionals, public health officials, and indoor air quality professionals. It may serve as a reference for anyone who designs, builds, operates, inspects, maintains, or otherwise works with buildings, heating, ventilating and air conditioning (HVAC) equipment, and/or portable air cleaners/sanitizers. This includes home services professionals, builders, remodelers, contractors, and architects. In addition to providing general information about the types of pollutants affected by air cleaners, this document discusses the types of air-cleaning devices and technologies available, metrics that can be used to compare air-cleaning devices, the effectiveness of air-cleaning devices in removing indoor air pollutants, and information from intervention studies on the effects that air cleaners can have on health and on health markers. A briefer companion publication, designed for the general public, Guide to Air Cleaners in the Home, is also available on the…

We investigated outdoor and indoor ultrafine particle number concentrations (PNC) from 16 residences located in two study areas in the greater Boston metropolitan area (MA, USA) for evidence of aviation-related impacts. During winds from the direction of Logan International Airport, that is, impact-sector winds, an increase in outdoor and indoor PNC was clearly evident at all seven residences in the Chelsea study area (∼4−5 km from the airport) and three out of nine residences in the Boston study area (∼5−6 km from the airport); the median increase during impact-sector winds compared to other winds was 1.7-fold for both outdoor and indoor PNC. Across all residences during impact-sector and other winds, median outdoor PNC were 19 000 and 10 000 particles/cm3, respectively, and median indoor PNC were 7000 and 4000 particles/cm3, respectively. Overall, our results indicate that aviation-related outdoor PNC infiltrate indoors and result in significantly higher indoor PNC. Our study provides compelling evidence for the impact of aviation-related emissions…
