Frequently Asked Questions About LG Water Filters
1. How often should I replace my LG refrigerator water filter?
LG recommends replacing your water filter every 6 months or after filtering 200 gallons of water, whichever comes first. However, if you notice reduced water flow, changes in taste or odor, or if your filter indicator light turns red, you should replace the filter immediately regardless of how long it's been installed. Households with higher water usage or poor source water quality may need to replace filters more frequently.
2. What's the difference between LG LT700P and LT1000P filters?
While both filters provide excellent filtration, they're designed for different LG refrigerator models and have slightly different specifications. The LT700P is compatible with a wider range of LG models and is certified to NSF standards 42, 53, and 401, making it effective against emerging contaminants including pharmaceuticals.

Both offer 6-month lifespans and reduce over 99% of common contaminants, but you must use the filter specifically designed for your refrigerator model.
3. Are compatible LG water filters as good as genuine LG filters?
High-quality compatible filters, such as Smart Filter products, can perform just as well as genuine LG filters when they're certified to the same NSF standards. Reputable compatible filters use similar carbon block technology and are manufactured to the same specifications as OEM filters. The key is to choose compatible filters that are NSF certified and come from trusted manufacturers. These filters offer the same filtration performance and fit while typically costing 30-50% less than genuine LG filters, making them an excellent value for budget-conscious consumers.
4. How do I know which LG water filter fits my refrigerator?
The best way to identify the correct filter is to check your refrigerator's model number, which is located on a label inside the refrigerator, typically on the side wall or ceiling of the fresh food compartment. You can also check your owner's manual or look at your current filter for the model number (LT500P, LT600P, LT700P, LT800P, or LT1000P). Additionally, LG's website offers a filter finder tool where you can enter your refrigerator model number to find the compatible filter.
5. Why does my water taste bad after installing a new LG filter?
A slight carbon taste immediately after installing a new filter is completely normal and harmless. This occurs because of loose carbon particles from the manufacturing process. To eliminate this taste, flush your new filter by running 2-3 gallons of water through the dispenser before drinking. This process typically takes 3-5 minutes and will clear out any carbon fines and air from the system. If the bad taste persists after flushing, the filter may be defective, or there could be an issue with your water source that requires investigation.
6. Can I use my LG refrigerator without a water filter?
While most LG refrigerators will operate without a filter installed, it's not recommended. Running your refrigerator without a filter means you'll be drinking and making ice with unfiltered water, which may contain chlorine, sediment, and potentially harmful contaminants. If you choose to operate without a filter, you'll need to install a filter bypass plug (usually included with your refrigerator) to maintain proper water flow. However, for health and taste reasons, it's always best to keep a properly functioning filter installed.
7. What contaminants do LG water filters remove?
LG water filters certified to NSF standards 42 and 53 remove a wide range of contaminants including chlorine taste and odor (up to 97%), lead, mercury, asbestos, benzene, and cysts like Giardia and Cryptosporidium. Some models, like the LT700P, are also certified to NSF 401, which means they reduce emerging contaminants including certain pharmaceuticals, pesticides, and industrial chemicals. However, LG filters do not remove beneficial minerals like calcium and magnesium, which contribute to water's taste and health benefits.
8. How do I reset the filter indicator light on my LG refrigerator?
After installing a new filter, locate the filter reset button on your refrigerator's control panel (it may be labeled "Filter Reset" or have a filter icon). Press and hold this button for approximately 3 seconds until the indicator light changes from red to green or turns off, depending on your model. If the light doesn't reset, try unplugging your refrigerator for a few minutes, then plug it back in and attempt the reset again. Some newer LG models may reset automatically when a new filter is installed.
9. Why is my water flow slow after changing the LG filter?
Reduced water flow immediately after installing a new filter is usually caused by air trapped in the water line. Run 2-3 gallons of water through the dispenser to purge the air from the system. If water flow remains slow with a new filter, ensure the filter is properly installed and fully seated in the housing. If you're experiencing slow flow with an older filter (approaching 6 months), the filter is likely clogged with contaminants and needs replacement, even if the indicator light hasn't turned red yet.
10. How much money can I save by using a refrigerator water filter instead of buying bottled water?
The savings are substantial. A typical LG water filter costs between $25-$50 and filters 200 gallons of water over 6 months. This equals about $0.12-$0.25 per gallon. In comparison, bottled water costs approximately $1-$2 per gallon. For a family drinking 2 gallons of water per day, using a refrigerator filter instead of bottled water can save $500-$1,000 per year. Additionally, you'll reduce plastic waste and your environmental impact while enjoying water that's often cleaner and better-tasting than many bottled water brands.
