The RF217ACRS does not come with an internal water filter for the icemaker. Instructions for installing an external water filtration system can be found on pages 17-18 of the User Manual, which can be downloaded from this link: http://tinyurl.com/29ctyvw
Please note that the Samsung part number (DA29-00015A) mentioned on page 18 has been discontinued. Your local retailer should be able to help you choose a filtration system that best meets your needs.
Thank you for the question,
