Write the date and mark the day of the week on the Vacuum Bag Kit with the marking pen provided. Obtain the vacuum that is used most frequently in your home (Photo 2). If the vacuum that is used most frequently in your home is a handheld vacuum, obtain the standard sized vacuum that is used most frequently. If you do not have a standard sized vacuum, collect the dust from a hand-held vacuum. Open the plastic-lined towel and place it on the floor next to the vacuum cleaner.	Photo 2.

If you have a vacuum with a bag
Carefully remove the bag from your vacuum cleaner. Holding the vacuum bag over the plastic-lined towel, place the vacuum bag on the aluminum foil provided. Fold the aluminum foil around the vacuum bag. Place the foil-wrapped vacuum bag in the 2-gallon zip-lock bag provided. If you need to bend the foil-wrapped vacuum bag to fit it inside the zip-lock bag, that’s okay. Just be careful not to spill the dust. Carefully squeeze any excess air out of the zip-lock bag. Seal the zip-lock bag. (Go to step 10 below.)	Photo 3a. Wrapping the vacuum bag in aluminum foil. Photo 3b. Vacuum bag wrapped in aluminum foil and placed in sealed zip-lock bag.
If you have a bagless vacuum
Carefully remove the dust collection cup from your vacuum cleaner. Holding the vacuum dust collection cup over the plastic-lined towel provided, pour the dust onto the aluminum foil provided. If the contents are dense and do not pour out easily, reach in and grab the dust with your fingers. Make sure you have removed as much of the fine dust as possible. Shake if necessary. Fold the aluminum foil around the dust. Place the foil-wrapped dust in the 2-gallon zip-lock bag. If you need to bend the foil-wrapped dust to fit it inside the zip-lock bag, that’s okay. Just be careful not to spill the dust. Carefully squeeze any excess air out of the zip-lock bag. Seal the zip-lock bag.	Photo 4a. Aluminum foil layed out on top of plastic-lined towel. Photo 4b.

Open the FedEx shipping box and place the zip-lock bag containing the vacuum bag or vacuum dust and the packing slip inside the box (Photo 11). Seal the box with the provided tape.	Photo 11. Place packing slip and sample in FedEx box.
Call FedEx to schedule a pick up (1-800-463-3399) for the next day or bring to a FedEx office the same day. This is prepaid. There will be no charge to you. Seal the FedEx box. Write the date that the Vacuum Bag Kit will be picked up or dropped off on the prepaid, addressed FedEx label and attach it to the FedEx envelope (Photo 12).	Photo 12.
