Barrhaven Home Inspectors Inc.

Description

- Inside the building, the air pump sampling should run for 10 minutes. If there is a lot of indoor activity, then the air pump sampling should be reduced to 5 minutes. If there is an active source of dust, such as construction or cleaning, then the air sampling time should be reduced to 1 minute. Be sure to follow the recommendations of the manufacturer of the sampling device or collector; there are some devices that are designed to take a sample in 5 minutes (i.e. Z5 cassette).

- There are many different types of air pumps, measurement meters, and spore collectors that can be used for an air sample at a mould inspection. The air pump should be adjusted to collect air at a flow rate that is recommended by the manufacturer of the collection device. The flow rate could be 15, 10 or even 5 liters per minute. The result of an air pump sample is recorded in spores per meter cubed (spores/m3).
