How to Replace Your LG Water Filter Replacement Cartridge: A Complete Step-by-Step Guide
Maintaining clean, fresh-tasting water from your LG refrigerator is essential for your family's health and well-being. Regular replacement of your LG water filter cartridge ensures that contaminants, chlorine, and other impurities are effectively removed from your drinking water. In this comprehensive guide, we'll walk you through everything you need to know about replacing your LG water filter replacement cartridge.
Why Regular Water Filter Replacement Matters
Your LG refrigerator's water filter works tirelessly to provide clean, safe drinking water. Over time, the filter becomes saturated with contaminants and loses its effectiveness. LG recommends replacing your water filter every 6 months or after filtering approximately 200 gallons of water, whichever comes first. Failing to replace your filter on schedule can result in:
- Reduced water flow and ice production
- Unpleasant taste and odor in your water and ice
- Decreased filtration effectiveness
- Potential damage to your refrigerator's water system
- Bacterial growth in an old, saturated filter
Identifying Your LG Water Filter Model
Before purchasing a replacement filter, you need to identify which model is compatible with your LG refrigerator. The most common LG water filter models include:
LG LT700P Water Filter
The LG LT700P is one of the most popular LG refrigerator water filters. It's compatible with many LG French door and side-by-side refrigerator models. This filter reduces chlorine taste and odor, sediment, and other contaminants while maintaining beneficial minerals in your water.
LG LT1000P Water Filter
The LG LT1000P filter is designed for select LG refrigerators and provides excellent filtration performance. It's NSF certified to reduce various contaminants and is easy to install without tools.
LG LT800P Water Filter
The LG LT800P is a vertical filter that fits in the upper right corner of your refrigerator compartment. It's known for its compact design and effective filtration capabilities.
LG LT500P Water Filter
The LG LT500P is designed for specific LG refrigerator models and offers reliable water filtration with easy twist-and-lock installation.
LG LT600P Water Filter
The LG LT600P filter is compatible with various LG refrigerator models and provides up to 6 months of clean, fresh-tasting water.
Step-by-Step Guide: How to Replace Your LG Water Filter
Method 1: Replacing Internal Filters (LT700P, LT1000P)

Open your refrigerator door and look for the filter housing. For most LG models with LT700P or LT1000P filters, you'll find it in the upper right corner of the fresh food compartment.
Step 2: Remove the Old Filter
Push the filter housing cover to open it. Twist the old filter counterclockwise (to the left) about a quarter turn until it releases. Pull the filter straight out. 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. Remove any protective caps or seals from both ends of the filter.
Step 4: Install the New Filter
Insert the new filter into the housing, aligning the arrow or indicator marks. Push the filter in firmly and twist clockwise (to the right) until it locks into place. You should feel it click when properly seated.
Step 5: Close the Cover
Close the filter housing cover until it clicks shut.
Method 2: Replacing Vertical Filters (LT800P)
Step 1: Locate the Filter
The LT800P filter is typically located in the upper right corner inside the refrigerator compartment.
Step 2: Remove the Old Filter
Lift the filter cover. Press the eject button to release the old filter, then pull it straight down and out.
Step 3: Install the New Filter
Remove packaging from the new filter. Insert the new filter straight up into the housing until it clicks into place.
Step 4: Close the Cover
Lower the filter cover back into position.
Method 3: Replacing Base Grille Filters (LT500P, LT600P)
Step 1: Locate the Filter
Look at the bottom front of your refrigerator. The filter is located behind the base grille.
Step 2: Remove the Old Filter
Twist the filter cap counterclockwise about a quarter turn and pull the filter straight out.
Step 3: Install the New Filter

Important Post-Installation Steps
Flush Your New Filter
After installing a new LG water filter, it's crucial to flush the system to remove any carbon fines or air from the filter. Follow these steps:
- Dispense water for 5 minutes (approximately 2-3 gallons) to flush the system
- Discard the first few batches of ice made after filter replacement
- Check for any leaks around the filter housing
- Ensure water flows smoothly without sputtering
Reset the Filter Indicator Light
After installing your new filter, reset the filter status light on your refrigerator:
- Locate the "Filter Reset" or "Ice Plus" button on your control panel
- Press and hold the button for 3-5 seconds
- The filter indicator light should turn off or change color (typically from red to green or blue)
- If your model doesn't have a dedicated reset button, consult your owner's manual
Choosing Between OEM and Compatible Filters
When shopping for replacement filters, you'll encounter two main options:
OEM (Original Equipment Manufacturer) Filters
These are genuine LG filters like the LT700P, LT1000P, LT800P, LT500P, and LT600P. They're manufactured by LG specifically for your refrigerator model and come with LG's quality guarantee.
Compatible Aftermarket Filters
High-quality compatible filters offer the same filtration performance as OEM filters at a more affordable price point. Look for filters that are NSF certified and specifically designed to be compatible with your LG model. Many compatible filters meet or exceed OEM specifications while providing significant cost savings.
Troubleshooting Common Issues
Water Flow is Slow After Replacement
If water flow is reduced after installing a new filter, the filter may not be properly seated. Remove and reinstall the filter, ensuring it clicks into place. Also, make sure you've flushed the system adequately.
Filter Won't Lock Into Place
Ensure you're using the correct filter model for your refrigerator. Check that you've removed all packaging materials and that you're aligning the filter correctly before twisting.
Water Tastes Strange After Replacement
This is usually due to carbon fines from the new filter. Continue flushing the system with 2-3 more gallons of water. The taste should improve significantly.
Filter Indicator Light Won't Reset
Try holding the reset button longer (up to 10 seconds). If it still won't reset, unplug your refrigerator for 30 seconds, then plug it back in and try again.
Maintaining Your LG Refrigerator Water System
Beyond regular filter replacement, follow these tips to maintain optimal performance:
- Mark your calendar for filter replacement every 6 months
- Clean the exterior of the filter housing periodically
- Check for leaks around the filter area during routine cleaning
- Keep spare filters on hand so you're never without clean water
- Monitor your water quality—if you notice changes before the 6-month mark, replace the filter early
Where to Buy LG Water Filter Replacement Cartridges
Finding the right replacement filter for your LG refrigerator is easy. Whether you need an LG LT700P, LT1000P, LT800P, LT500P, or LT600P filter, or a compatible alternative, make sure to purchase from a reputable supplier that offers genuine or certified compatible products.

Frequently Asked Questions About LG Water Filter Replacement
1. How often should I replace my LG water filter?
Answer: LG recommends replacing your water filter every 6 months or after filtering approximately 200 gallons of water, whichever comes first. However, if you notice reduced water flow, unusual taste or odor, or if your household uses more water than average, you may need to replace it more frequently. The filter indicator light on your refrigerator will also alert you when it's time for a replacement.
2. What's the difference between LG LT700P, LT1000P, LT800P, LT500P, and LT600P filters?
Answer: These filters are designed for different LG refrigerator models and have different physical designs and installation locations. The LT700P and LT1000P are typically internal filters located in the upper right corner of the fresh food compartment. The LT800P is a vertical filter also located inside the refrigerator. The LT500P and LT600P are often base grille filters located at the bottom front of the refrigerator. While they all provide excellent filtration, you must use the specific model designed for your refrigerator. Check your owner's manual or the existing filter to identify the correct replacement.
3. Can I use a compatible aftermarket filter instead of a genuine LG filter?
Answer: Yes, you can use high-quality compatible aftermarket filters as long as they're specifically designed for your LG refrigerator model and are NSF certified. Many compatible filters meet or exceed OEM specifications and offer the same filtration performance at a lower cost. Look for reputable brands that guarantee compatibility and performance. However, ensure the filter is certified to reduce the same contaminants as the original LG filter.
4. 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 properly seated. First, ensure the filter is correctly installed and locked into place. Then, flush the system by dispensing 2-3 gallons of water to remove air pockets. If the problem persists, remove and reinstall the filter, making sure it clicks securely. In rare cases, a defective filter could be the issue—try a different filter if problems continue.
5. Do I really need to flush the filter after installation?
Answer: Yes, flushing is essential. New filters contain carbon fines (tiny carbon particles) that need to be flushed out before consumption. Flushing also removes air from the system and ensures proper water flow. Run 2-3 gallons of water through the dispenser (about 5 minutes) and discard the first few batches of ice. Skipping this step can result in cloudy water, black specks in your water or ice, and an unpleasant taste.
6. How do I reset the filter indicator light on my LG refrigerator?
Answer: After installing a new filter, locate the "Filter Reset" button on your refrigerator's control panel (it may also be labeled "Ice Plus" or have a filter icon). Press and hold this button for 3-5 seconds until the indicator light changes color or turns off. The light typically changes from red to green or blue. If your model doesn't have a dedicated button, consult your owner's manual for specific reset instructions, as the process varies by model.
7. What contaminants do LG water filters remove?
Answer: LG water filters are NSF certified to reduce various contaminants including chlorine taste and odor, lead, mercury, asbestos, benzene, carbofuran, p-Dichlorobenzene, and other potentially harmful substances. They also reduce sediment and particulates while retaining beneficial minerals like calcium and magnesium. The specific contaminants reduced depend on the filter model and its certifications. Check the filter packaging or manufacturer's specifications for detailed information about what your specific filter removes.
8. Can I clean and reuse my LG water filter instead of replacing it?
Answer: No, LG water filters are designed for single use and cannot be effectively cleaned or reused. The filtration media inside becomes saturated with contaminants over time and loses its effectiveness. Attempting to clean or reuse a filter won't restore its filtration capability and could actually release trapped contaminants back into your water. For your family's health and safety, always replace the filter with a new one every 6 months.
9. What should I do if my filter is leaking after installation?
Answer: If you notice water leaking around the filter area, first check that the filter is properly installed and fully seated. Remove the filter and reinstall it, ensuring it's aligned correctly and twisted until it clicks into place. Check that you've removed all packaging materials, including any protective caps. Inspect the O-rings on the filter for damage. If the leak persists, the filter may be defective—try a different filter. Also ensure you're using the correct filter model for your refrigerator, as an incompatible filter won't seal properly.
10. Where can I find the model number of my current LG water filter?
Answer: The model number is printed directly on the filter cartridge itself. Remove your current filter and look for a label or text printed on the side or end of the filter—you'll see numbers like LT700P, LT1000P, LT800P, LT500P, or LT600P. You can also find this information in your refrigerator's owner's manual, on a label inside the refrigerator door, or on the filter housing cover. If you're still unsure, you can look up your refrigerator's model number (found on a label inside the fridge or on the back) on LG's website to determine the compatible filter model.
