No, there are multiple, different types of filters responsible for removing components of the air.

Carbon Dioxide, being the main culprit, is absorbed on a zeolite and dumped overboard (by reheating).

Other minor impurities (such as methane and thiols from your butt) are captured in Carbon filters, which are regularly replaced and disposed of.
