Patent ID: 7871821

Claim:
A method for forming a simulated household dust composition, the method comprising the steps of: A) providing a first container and a second container; B) introducing a fibrous fraction component into the first container, the fibrous fraction component comprising up to about 45% to about 55% by weight of the simulated household dust, and wherein about 78% to about 100% by weight of the fibrous fraction component is formed from cotton fibers; C) mixing the fibrous fraction component in the first container; D) introducing a particulate fraction component into the second container, the particulate fraction component comprising from about 45% to about 55% of the simulated household dust, and wherein about 40% to about 70% by weight of the particulate fraction component is formed from skin cells; E) mixing the particulate fraction component in the second container; and F) mixing the fibrous fraction component from the first container with the particulate fraction component from the second container.
