If you’ve got an LG French Door fridge like the LFX28979ST, the filter you choose actually matters. The LG LFX28979ST water filter - an LT700P-compatible cartridge - is made to fit both 00 and 01 versions, so you don’t have to second guess the fit.

It helps reduce chlorine taste and odor, along with the common impurities that affect how your water looks and tastes. You don’t notice it much at first… but once the filter wears out, it’s obvious.

Installation is easy. Twist, lock, done. No tools needed. And yes, it’s NSF 42 and 53 certified, so it’s doing what it’s supposed to. Replace it every 6 months. Keeps the flow steady. Keeps the ice clear. Simple habit, big difference.
