Matched-weight filters are often chosen when using gravimetric analysis to analyze a sample because no filter preweighing or conditioning is needed. Matched-weight refers to two filters that are matched in weight and loaded into a cassette in a strictly controlled lab environment of 68 F (± 0.5 F) temperature and 50% (± 0.5%) humidity.
