This grade has finer particle retention than Grade 292 but with slightly lower filtration speed. Grade 292 a also has higher absorption than Grade 292. It is used in general laboratory applications to retain particles above 2 μm in size. Grade 292 a is also found in agricultural and environmental laboratories for plant growth trials, soil testing, and air analysis for monitoring specific contaminants and in the filtration of organic and sulfide precipitates.
