The present invention discloses a filter apparatus () for a liquid vessel (), in particular for aqueous urea solution. The filter apparatus () comprises a filter housing () having a through opening (), and a liquid-permeable and air-impermeable filter element () which is connected to the filter housing () in such a way that the filter element () closes the through opening () of said filter housing () at least partially, with the result that the through opening () is liquid-permeable and air-impermeable. The filter apparatus () comprises, furthermore, at least one liquid outlet connection () which is fluidically connected to the through opening () of the filter housing (). The filter apparatus () according to the invention is distinguished by the fact that it comprises a heating device () which is connected directly to the filter housing () and/or is integrated into the filter housing (). As a result, the volume which surrounds the filter apparatus () is heated reliably.
