Collecting a sample is easy!

• First, clearly label your sample bag with your address and the date the bag was filled and sealed. Note: this is sometimes easier to do BEFORE you fill your bag with dust.

• Put the entire contents of your vacuum cleaner bag, or cylinder (or several cylinders worth if needed), into your re-sealable bag. Carefully release excess air and seal it up. You may prefer to fill your sample bag in a well-ventilated area, and use a disposable mask, if you are concerned about inhaling the dust.

• • We recommend that you place this bag into another bag, as this helps protect the label and protects against any leaks.

A useful video explaining the process is available here:

All that is left is for you to send us your sample! Please mail your sample to one of the locations detailed below. Once we receive your sample, we will analyse it and email you back within 3-6 months with a bespoke report of the metals/trace elements within your dust sample.
