This cartridge is built for side-by-side refrigerators and is labeled with the USC100 model string, which is the specific identifier you need to match against your current unit. It is rated for 1500 liters of water, a capacity that dictates how often you will need to schedule a replacement.

Look at the product photo to confirm the physical length and the specific shape of the inline connector. If your existing filter is a different length or has a different connector geometry, this unit will not seat correctly in the line, leading to leaks or a complete failure to filter.

The title specifies a 5-year lifespan for this inline filter, which is a significant difference from the standard 6-month cycles of most other cartridges on this list. This longer duration is the primary selling point for those who want to reduce the frequency of maintenance.

Check the photo to see the exact dimensions of the inline housing. A 5-year filter often has a larger physical footprint to accommodate more media, so if your refrigerator's filter housing is compact, this unit may not fit inside the cabinet or may block the door from closing properly.

This filter is marked with the 15UC-UF model number and claims a 0.01 μm filtration rating, which is a specific technical spec you should verify against your refrigerator's requirements. It is designed for a 2-year replacement cycle, which is a middle ground between standard and extended-life filters.

In the product image, look closely at the connector type. If your current filter uses a different fitting, this inline unit will not connect. The 0.01 μm rating also implies a higher resistance to water flow, so if your ice maker is already slow, this filter may exacerbate the issue rather than solve it.

This is a direct replacement for the Frigidaire EPTWFU01 model, a specific part number that is critical for compatibility. It is a white, single-count cartridge designed for Frigidaire refrigerators that use this particular filter system.

The photo shows the standard white plastic housing. If your refrigerator uses a different Frigidaire filter model, such as the ULTRAWF or FPPWFU01, this EPTWFU01 will not fit. The shape and the internal media configuration are different, so using the wrong part number will result in a filter that does not lock into place or does not filter correctly.

This listing is for a 3-pack of UKF8001 filters, which are replacements for the EveryDrop Filter 4. The 3-pack format is a bulk purchase option, which is useful if you want to stock up and reduce the frequency of ordering.

Look at the photo to confirm that the UKF8001 model number is clearly visible. If your refrigerator uses a different EveryDrop filter, such as the Filter 2 or Filter 3, this UKF8001 will not be compatible. The 3-pack also means you are committing to a specific volume of water filtration, so if your usage is low, you may not use all three before they expire.

This is the LG LT500P filter, which has a 6-month or 500-gallon capacity. The LT500P model number is the key identifier for LG refrigerators that use this specific filter system.

The photo shows the white, rectangular housing. If your LG refrigerator uses a different filter model, such as the LT700P, this LT500P will not fit. The internal media and the connector type are different, so using the wrong part number will result in a filter that does not lock into place or does not filter correctly.

This is the Frigidaire FPPWFU01 filter, which is a specific model number that is critical for compatibility. It is a white, single-count cartridge designed for Frigidaire refrigerators that use this particular filter system.

The photo shows the standard white plastic housing. If your refrigerator uses a different Frigidaire filter model, such as the EPTWFU01 or ULTRAWF, this FPPWFU01 will not fit. The shape and the internal media configuration are different, so using the wrong part number will result in a filter that does not lock into place or does not filter correctly.

This is the Frigidaire ULTRAWF filter, which is a specific model number that is critical for compatibility. It is a white, single-count cartridge designed for Frigidaire refrigerators that use this particular filter system.

This is the Waterdrop INL inline filter, which is designed for both refrigerators and ice makers. The INL model number is the key identifier for this specific filter system.
