Glass Fibre Filters are the non-organic filter media that consist of fine glass fibres and are used for filtering liquids and gases which contain a large amount of particles. They provide very fast flow rate and good dirt holding capacity, hence, are useful in pre-filtration, air sampling, and gravimetric measurement. They are resistant to heat and most of the chemicals, hence, find their application in environmental, chemical, pharmaceutical, and industrial laboratories for performing emission measurement, water testing, and particulate sampling, among others.
