Frequently asked

What water filter does a LSXS22423B refrigerator use?

The LSXS22423B uses the LT800P water filter.

Does the LT800P remove lead?

Yes - the LT800P is NSF/ANSI 53 certified to reduce lead.

Should I buy the OEM filter or an aftermarket one?

The OEM LT800P is the safe, exact-fit choice. A cheaper aftermarket filter can fit the same slot too - just confirm it carries its own independent NSF certification for the contaminants you care about, since a generic aftermarket filter without certification isn't proven to remove anything.

How often should I replace the LT800P?

Most refrigerator filters are replaced every 6 months regardless of the exact model - use your fridge's filter-change indicator as the trigger if it has one.

Where is the water filter on a LSXS22423B?

Location varies by fridge design - commonly inside the fridge compartment (upper right or lower kickplate/grille) or in the water line behind the unit. Check your owner's manual for the exact spot on this model.
