Therefore, we recommend replacing your refrigerator's water filter typically every six months or when the gallon capacity is reached. We offer compatible replacements for Whirlpool refrigerator water filters, Kenmore, Frigidaire, Samsung, LG, Maytag and other popular refrigerator brand water filters.

While I am sure you can safely go a little longer than six months before replacing your filter itâs not a good idea to leave the same filter in there forever.
