polyvinyl chloride

Polyvinyl chloride

Degradation during service life, or after careless disposal, is a chemical change that drastically reduces the average molecular weight of the polyvinyl chloride polymer. Since the mechanical integrity of a plastic depends on its high average molecular weight, wear and tear inevitably weakens the material.

Filtration Efficiency - an overview | ScienceDirect Topics

Very high efficiency air filters, for which efficiencies range upwards from 99.99%, are sometimes characterized in terms of percentage penetration, and are in fact classified as ULPA (Ultra Low Penetration Air) filters; thus, Eurovent class EU 15 can be described as having an efficiency of 99.9995% or a penetration of 0.0005%.

High efficiency particulate air (HEPA) filters must meet the efficiency rating of 99.97%, on particles as small as 0.3 microns, set by the US Department of Energy in order to be a true HEPA filter 5. Some HEPA filters marketed for consumers do not meet these standards and are not true HEPA filters with the same capability or efficiency.
