To ensure reliable filtration performance in practical applications, bubble point testing is typically performed. This test is a crucial method for evaluating the minimum pore size and uniformity of filter elements. The method involves gradually increasing the pressure in a specific liquid medium to determine when the filter element begins to bubble, thus identifying its minimum pore size.
