US Patent 7074260 - Nanotube Filter For Air Conditioner

Carbon materials have been used in the past in filters of air conditioners for adsorption of contaminants. This patent from Samsung teaches that nanotubes have increased ability at removing VOCs (volatile organic compounds) in an air conditioner. Claim 1 reads:

1. A filter for an air conditioner, comprising: a carbon nanotube, wherein nano-sized metal particles of at least one type of metal are deposited into the carbon nanotube.
