COLLECTION OPTIONS

Choose the method that matches your test

Different services use different sample types. Follow the method associated with your specific order.

DUST COLLECTION

Swiffer Sampling

A convenient option for collecting settled dust from indoor surfaces for eligible environmental testing.

DUST COLLECTION

Where Should I Collect Dust?

For a representative settled-dust sample, collect from dry interior surfaces where dust naturally accumulates over time.

GOOD PLACES TO SAMPLE

Tops of interior door frames, moldings, entertainment centers, shelves, dressers, nightstands, and HVAC return vents.

AREAS TO AVOID

Bathrooms, laundry rooms, kitchens, visible mold directly, rusty areas, construction or drywall dust, and areas close to stoves, heaters, or other high-heat sources.

Collect enough visible dust. Continue sampling until the cloth contains a clearly visible amount of settled dust. Very limited sample material may affect the laboratory’s ability to complete the requested analysis reliably.

Using your own cloth? Use a brand-new, unused disposable sweeping cloth (such as a Swiffer-type cloth) and use only one cloth per test.

Keep paperwork separate from the sample. Do not place the Chain of Custody form inside the plastic bag containing the sample.

Vacuum Sampling

A vacuum sampling device can be selected when a more controlled dust-collection method is preferred.

SWAB COLLECTION

Dry Swab

For services that accept swabs, submit a dry swab and keep it clearly identified with the corresponding sample information.
