In the air filtration segment, nonwovens compete with a wide range of other materials including paper, fiberglass and wovens in applications including dust collection at large industrial installations, heating, ventilating and air conditioning (HVAC) systems, carburetors, vacuum cleaners and air cabin filters. Common nonwoven technologies include spunlace, meltblown and needle punched. On the liquid side of the industry, applications include pool and spa filters, oil and lubricant filtration, water filtration, tea bags and coffee filters and blood filtration. Nonwoven technologies commonly used in this subsegment include spunlace, meltblown and spunbonded.(from www.nonwovens-industry.com).
