A system and method for removing contaminants in a fluid, particularly water from lubricating oil, is provided which may comprise a particulate zeolitic adsorbent in conjunction with a non-porous PTFE barrier that has been modified to be permeable to water and impermeable to oil. Such a system is capable of reducing the level of water in lubricating oil to less than 100 parts per million.
