InstructionsRemove the housing cover and insert the filter cartridge down into the well in the housing. It fits in the well diagonally. The bottom of the filter is more narrow than the top and the black side faces outward (toward the spout). If the fit is too tight, it is either in upside down or in the wrong groove at the front (move it back one groove). Rinsing the filter before use will help remove any loose bits of charcoal, which are harmless.Filter should be changed approximately every six to eight weeks.Made in Mexico.
