Dust in Residential Air. Sampling kit and laboratory test


The kit includes several sampling cassettes, a sampling pump, and a sampling instruction.  Please note that the cassettes and the pump should be returned for calibration and analysis to our laboratory in London, Ontario, Canada within a month from this order.  Your samples will be analyzed using a standard method NIOSH 0500, which was modified by our laboratory to improve the method sensitivity. During the test, we compare the weight of the filter with the accumulated airborne dust against the weight of the fresh filter.   Once the test is completed, we produce a formal laboratory report, which includes all findings and observations.

The price includes a 1-month equipment rental, prepaid laboratory analysis, and a laboratory report. The return shipping cost is not included in the price. Please check the shipping tab for more information. The standard turnaround time for this test is 10 business days. You will be able to request expedited service when you return the samples for testing.



The laboratory reports produced by our lab will show the concentration of Total Suspended Dust in air expressed in micrograms per meter cube (µg/m³). The following reference numbers will help you to decide if your house requires additional cleaning:

<30 µg/m³ – concentration of dust in the air was below the laboratory detection limit. The dust level is negligible

120 µg/m³ – This is recommended limit for clean air (Ambien Air Quality Criteria Ontario 2012)

120-15,000 µg/m³ – Dust level in the air is too high and likely dangerous. The source of dust should be eliminated.

>15,000 µg/m³ – Dust level is dangerously high and exceeds the regulated limit for the industry. Re-entry is not allowed without personal protection equipment.
