According to Whirlpool's blog: Not all replacement water filters are equal, and there are plenty of knockoffs out there. Their filters (and their everydrop brand) reduce up to 73 contaminants depending on your fridge, including up to 99.9% of lead. They also suggest looking for filters certified by NSF International, an independent group, and they say theirs are certified in all three categories: taste and odor, health concerns, and emerging contaminants.
My two cents: that filter is easy to forget about. Every 6 months is the common suggestion, but how often you need to swap it really depends on your water quality to begin with. Hard water or a lot of sediment can clog a filter sooner, and cleaner water may let it go longer. If your water starts tasting off, has cloudy discoloration, or the flow slows down, that's a good sign it's time. When you buy a replacement, check the box for the NSF certification and make sure the part number matches for your fridge.
If you're not sure which one your fridge takes, send me the model number (inside the fridge door or wall) and I'll help you figure it out and can also order OEM for you.
