Round Robin Testing Confirms Comparable Performance Results
When Blue Heaven ASHRAE Dust was developed a comprehensive series of tests were conducted with three major filter manufacturers to verify the test results were directly comparable with other sources of dust commonly available.


Reliable Test Results Require Consistent Dust Formulation
Reliable test results that allow accurate comparability from test to test require dust with a consistent formulation. Blue Heaven dust is manufactured in strict accordance with ASHRAE specifications (52.1 and 52.2). Our process control and state-of-the-art blending equipment assure each batch is produced per spec and with the exact same formulation. Blue Heaven test technicians have 16 years experience producing ASHRAE dust.



The three components of ASHRAE dust are
blended into a standardized composite used
to load filters during the test procedure. A
vial of each component is shown, along with
the composite blend. (Left: Cotton Linters;
