Abstract
A hard disk drive (HDD) filter assembly may include an inlet for receiving an input gas, a cyclonic particle separator configured for separating certain sized particulates from the gas, and a trap chamber for securing the particulates separated from the gas. Such a filter assembly may be designed and configured to separate and secure nanoparticulates from the input gas, such as nanoparticulates with diameters less than around 100 nm. A filter assembly may further include a desiccant chamber for controlling the humidity of the cleaned gas and a membrane for absorbing and/or adsorbing some remaining particulates from the gas before the gas enters the main chamber of the HDD.
