Evaluation of Air Filtration Systems to Reduce Aerosol Transmission of PRRS
ثبت نشده
چکیده
(1) High-efficiency particulate air (HEPA) filtration: the HEPA-filtration system used a prefilter screen, a bag filter (Eurovent [EU] 8 rating), and a HEPA filter (EU13 rating). (2) 2×-low-cost filtration: The low-cost-filtration system contained mosquito netting (prefilter), 2 fiberglass furnace filters, and 2 electrostatic furnace filters. (3) Bag filtration: Bag filtration involved the use of a filter rated EU8 and a minimum efficiency reporting value (MERV) of 14. (4) Filter tested against particles derived from dioctylphthalate (DOP): The 95%-DOP, 0.3-μmfiltration system involved a pleat-in-pleat V-bank disposable filter with a 95% efficiency rating for particles 0.3 μm or greater in diameter and ratings of EU9 and MERV 15.

متن کاملForced-air warming design: evaluation of intake filtration, internal microbial buildup, and airborne-contamination emissions.
Forced-air warming devices are effective for the prevention of surgical hypothermia. However, these devices intake nonsterile floor-level air, and it is unknown whether they have adequate filtration measures to prevent the internal buildup or emission of microbial contaminants. We rated the intake filtration efficiency of a popular current-generation forced-air warming device (Bair Hugger model...
