How to Replace Your LG Side-by-Side Refrigerator Water Filter
Maintaining clean, fresh-tasting water and ice from your LG side-by-side refrigerator starts with regular water filter replacement. Whether you're a first-time owner or simply need a refresher, this comprehensive guide will walk you through everything you need to know about replacing your LG refrigerator water filter.
Why Regular Filter Replacement Matters
Your LG refrigerator's water filter plays a crucial role in removing contaminants, chlorine, sediment, and other impurities from your drinking water and ice. Over time, these filters become saturated with the very contaminants they're designed to remove, reducing their effectiveness and potentially affecting water taste and quality.
LG recommends replacing your refrigerator water filter every six months or after filtering approximately 200 gallons of water, whichever comes first. However, if you notice a decrease in water flow, unusual taste or odor, or if your filter indicator light turns on, it's time for a replacement regardless of the timeline.
Identifying Your LG Water Filter Model
Before purchasing a replacement filter, you'll need to identify which model your LG side-by-side refrigerator uses. The most common LG filter models include:
- LG LT700P - One of the most popular models, found in many LG French door and side-by-side refrigerators
- LG LT1000P - Commonly used in various LG refrigerator models with internal filtration
- LG LT800P - Features a compact design for specific LG refrigerator configurations
- LG LT500P - Used in select LG side-by-side and bottom freezer models
- LG LT600P - Another popular option for LG refrigerators with vertical filtration systems
You can find your filter model number on the existing filter cartridge itself, in your refrigerator's user manual, or on a label inside the refrigerator compartment near the filter housing.
Step-by-Step: Replacing Your LG Side-by-Side Water Filter
Most LG side-by-side refrigerators feature an internal water filter located in the upper right corner of the fresh food compartment. Here's how to replace it:
Step 1: Locate the Filter
Open your refrigerator door and look in the upper right corner of the fresh food section. You should see a cylindrical filter housing with a cover or cap.
Step 2: Remove the Old Filter
To remove the old filter:
- Push the filter housing cover to open it (some models may require you to press a release button)
- Grasp the filter firmly and turn it counterclockwise (usually about a quarter turn)
- Pull the filter straight out once it's unlocked
- Be prepared for a small amount of water to drip out - this is normal
Step 3: Prepare the New Filter
Remove your new LG water filter from its packaging. Some filters come with a protective cap - remove this before installation. Do not remove any O-rings or seals on the filter.
Step 4: Install the New Filter
To install the replacement filter:
- Align the new filter with the filter housing
- Insert the filter straight into the housing
- Turn the filter clockwise (usually about a quarter turn) until it locks into place
- You should feel or hear a click when it's properly seated
- Close the filter housing cover
Step 5: Flush the System
This is a critical step that many people skip. After installing a new filter, you must flush the system to remove any air and carbon fines:
- Dispense water through the refrigerator's water dispenser for at least 5 minutes (approximately 2.5 gallons)
- Discard this initial water - it may appear cloudy or contain small black particles (carbon fines), which is normal
- Continue flushing until the water runs clear and steady
Step 6: Reset the Filter Indicator
After installing your new filter, reset the filter indicator light:
- Locate the filter reset button (usually on the control panel or near the ice/water dispenser)
- Press and hold the button for 3-5 seconds until the indicator light changes or turns off
- Consult your specific model's manual if you can't locate the reset button
OEM vs. Compatible Filters: What's the Difference?
When shopping for replacement filters, you'll encounter two main options: OEM (Original Equipment Manufacturer) filters made by LG and compatible aftermarket filters.
OEM LG Filters
OEM filters are manufactured by LG specifically for their refrigerators. They guarantee compatibility and are tested to meet LG's specifications. Our store carries genuine LG filters including the LT700P, LT1000P, LT800P, LT500P, and LT600P models.
Compatible Aftermarket Filters
Compatible filters are manufactured by third-party companies to work with LG refrigerators. Quality compatible filters, like our Smart Filter line, are designed to meet or exceed OEM specifications while offering cost savings. We offer Smart Filter options compatible with LG models LT700P, LT1000P, LT800P, LT500P, and LT600P.
Both options can provide excellent filtration when sourced from reputable manufacturers. The choice often comes down to personal preference and budget considerations.
Troubleshooting Common Installation Issues
Filter Won't Lock Into Place
If your filter won't lock, ensure you're turning it in the correct direction (clockwise for installation). Also verify you have the correct filter model for your refrigerator.
Water Leaking After Installation
A small amount of dripping immediately after installation is normal. However, persistent leaking may indicate:
- The filter isn't fully seated - remove and reinstall
- The O-ring is damaged - inspect and replace if necessary
- You have the wrong filter model
Reduced Water Flow
If water flow is slow after installing a new filter:
- Ensure you've flushed the system adequately (at least 5 minutes)
- Check that the filter is fully locked into position
- Verify there are no kinks in the water supply line
Filter Indicator Light Won't Reset
If the indicator light won't reset:
- Ensure you're holding the reset button long enough (3-5 seconds)
- Try unplugging the refrigerator for 30 seconds, then plugging it back in
- Consult your owner's manual for model-specific reset procedures
Maintaining Your LG Refrigerator's Water System
Beyond regular filter replacement, consider these maintenance tips:
- Mark your calendar: Set a reminder for six months from installation to ensure timely replacement
- Monitor water quality: Pay attention to taste, odor, and flow rate as indicators of filter condition
- Clean the dispenser: Wipe down the water and ice dispenser area regularly to prevent buildup
- Check for leaks: Periodically inspect the filter housing and connections for any signs of moisture
- Use quality water: If your home has particularly hard water or well water, you may need to replace filters more frequently
Environmental and Health Benefits
Regular filter replacement isn't just about taste - it's about health and sustainability:
- Contaminant removal: Fresh filters effectively remove chlorine, lead, mercury, and other potential contaminants
- Reduce plastic waste: Using filtered refrigerator water reduces reliance on bottled water
- Cost savings: Filtered tap water costs significantly less than purchasing bottled water
- Convenience: Always have fresh, filtered water and ice available at home

Frequently Asked Questions About LG Side-by-Side Refrigerator Water Filters
1. How often should I replace my LG refrigerator water filter?
Answer: LG recommends replacing your refrigerator water filter every six months or after filtering approximately 200 gallons of water, whichever comes first. However, if you have a large family, use more water than average, or notice changes in water taste, flow, or quality, you may need to replace it more frequently. Always replace the filter when the indicator light activates.
2. What happens if I don't replace my LG water filter?
Answer: Failing to replace your water filter can lead to several issues: reduced water flow as the filter becomes clogged, decreased filtration effectiveness allowing contaminants to pass through, unpleasant taste or odor in your water and ice, and potential buildup of bacteria or mold in the saturated filter. An old filter essentially becomes ineffective at its primary job of purifying your water.
3. Are compatible aftermarket filters as good as OEM LG filters?
Answer: High-quality compatible filters from reputable manufacturers can perform as well as OEM filters. Look for filters that are NSF certified and specifically designed to meet or exceed OEM specifications. Our Smart Filter line, for example, is engineered to provide the same level of filtration as genuine LG filters while offering cost savings. Always purchase from trusted retailers to ensure you're getting a quality product.
4. Why is my water cloudy after installing a new filter?
Answer: Cloudy water immediately after installing a new filter is completely normal and is caused by air bubbles and carbon fines (tiny harmless carbon particles) being flushed from the new filter. This is why it's essential to flush the system by running water through the dispenser for at least 5 minutes (about 2.5 gallons) after installation. The water should run clear after proper flushing.
5. How do I know which LG filter model I need?
Answer: You can identify your filter model in several ways: check the label on your current filter cartridge, look in your refrigerator's user manual, find the model information on a sticker inside the refrigerator near the filter housing, or search online using your refrigerator's model number (found on a label inside the fridge or on the back). Common LG filter models include LT700P, LT1000P, LT800P, LT500P, and LT600P.
6. Can I use my LG refrigerator without a water filter?
Answer: Most LG refrigerators require a filter or a bypass plug to operate the water and ice dispenser. Running the refrigerator without either can cause leaks or prevent the water system from working. If you choose not to use a filter, you must install a filter bypass plug (usually included with your refrigerator or available for purchase). However, this means your water won't be filtered and may contain contaminants and chlorine.
7. Why is my water flow slow after installing a new filter?
Answer: Slow water flow after installing a new filter is usually caused by air trapped in the system or the filter not being fully seated. First, ensure the filter is locked completely into place by turning it clockwise until you hear or feel a click. Then, flush the system for at least 5 minutes to remove air pockets. If flow remains slow, check for kinks in the water supply line or verify you have adequate water pressure (LG recommends 20-120 psi).
8. How do I reset the filter indicator light on my LG refrigerator?
Answer: To reset the filter indicator light, locate the filter reset button on your refrigerator's control panel (it may be labeled "Filter Reset," "Ice/Water Filter," or have a filter icon). Press and hold this button for 3-5 seconds until the light changes color, turns off, or you hear a beep. The exact procedure may vary by model, so consult your owner's manual if this doesn't work. Some models may require you to press a combination of buttons.
9. Is it normal for water to drip when I remove the old filter?
Answer: Yes, it's completely normal for a small amount of water to drip when removing the old filter. The filter housing and lines contain water, so some spillage is expected. To minimize mess, place a towel beneath the filter housing before removal. The dripping should stop once the old filter is removed and the new one is installed. If you experience continuous leaking after installation, the new filter may not be properly seated.
10. Do LG water filters remove fluoride and other specific contaminants?
Answer: LG refrigerator water filters are primarily designed to reduce chlorine taste and odor, sediment, and certain contaminants like lead, mercury, benzene, and some pesticides. However, they typically do NOT remove fluoride, which requires specialized filtration. For specific contaminant reduction claims, check the filter's NSF certification and performance data sheet. LG filters are generally NSF certified for specific contaminant reduction, and this information should be available on the product packaging or manufacturer's website.
