Filtration Efficiency Testing

Filtration efficiency testing is a process used to determine how well a filtration system removes or reduces specific contaminants. This is achieved by testing the concentration of the specific contaminants before and after the filtration process. A higher filtration efficiency means that a greater amount of contaminants are being removed from the medium being filtered, such as air or water.

Typically, filtration efficiency testing involves exposing the filter to a specific concentration of particles and then measuring the amount that passes through. This can be done using a variety of testing methods, including laser particle counters, microbial challenge testing, or chemical analysis techniques.

Filtration efficiency can be affected by a variety of factors, including the size and shape of the particles, the flow rate of the medium, and the design and material of the filter itself. Therefore, it is important to conduct a thorough testing process that considers all of these variables.

STEMart provides comprehensive and reliable filtration efficiency testing services to determine the strength of the materials and how effective it is at protecting a wearer from inhaling a certain particle, and protect the wearer from the transmission of diseases, deadly viruses, and harmful particulates that can cause serious respiratory damage or other ailments.
