The life of refrigerator water filters is dependent upon the volume of contaminants in the water as well as the estimate of use of the filter. Well water is more likely to consist of contaminants not found in publicly treated water and may need more frequent filter changes. As a rule of thumb, the filter should be changed as specified by the manufacturer or at least every six months.
Carbon is the original substance used in water filtration methods because carbon has the potential to suck in many of the chemicals found in water. Most refrigerator water filters, which meet Nsf/Ansi 42 certification standards, use granular activated carbon (Gac) to attract chemicals and impurities responsible for bad taste and odor, such as those that are a by-product of chlorine. These filters are not capable, however, to rid water of more dangerous, health-threatening contaminants. The recipe by which water is channeled through Gac filters does not allow enough time to complete the absorption of such substances. Discrete bacteria are formed, trapped and allowed to multiply, which added contaminates water processed by the filters. Carbon is not capable to suck in heavy metals, such as lead. Gac filters may trap some heavy metals and sediments, but allow others to filter through to the yield water. Failure to change the water filter, every six months, allows unabsorbed water contaminants and newly formed bacteria to saturate the filter, forcing the filter to leak contaminants back into processed water. The water yield may consist of more contaminants than the filter was intended to take off in the first place.

Technology has lead to the improvement of more absorbent carbon-based filters, solid carbon block filters. These filters consist of solid blocks of carbon to suck in contaminants from water. Water takes longer to strain through carbon blocks than it does carbon granules, so that carbon blocks contribute enough time for the absorption of more health-threatening containments. While carbon block filters are capable to suck in toxics, pesticides, Tthm's and other contaminants, they cannot suck in heavy metals or contaminants that are by-products of agricultural fertilization, such as nitrates or sulfides. The compound of carbon blocks allows them to restrain heavy metals and bacteria away from yield water, however, nitrates and sulfides are not filtered. Even so, carbon block filters are enough to meet Nsf/Ansi 53 certification standards. Failure to change carbon block filters, every six months, allows contaminants to saturate the filter, forcing the filter to leak contaminants into the processed water. When sediments are not removed from water, those sediments buildup and corrode filter fittings and water fixtures, causing them to leak. This type of damage to filters and fixtures may cause the yield water to consist of more contaminants than the water input to the filter. Failure to change the filters might also sacrifice the water pressure, within the filtering system, forcing it to be ineffective.
Some refrigerator water filters may consist of fiber water filters. These filters are made of tightly wrapped fibers of rayon or spun cellulose, which trap rust, lead and other sediments found in water. When used alone, these filters are ineffective in reducing any chemical or health-threatening contaminants. Fiber filters are best suited for use with other types of filters to sacrifice the attentiveness of sediments. They should be replaced, every six months, to avoid a build-up of sediments that would force the filter to leak the contaminants back into the processed water.
