In this guide, we’ll explain why it’s important to replace your LG water filter, how to do it, and share limited-time deals to help you save on your next water filter purchase.
Why You Need to Replace Your LG Fridge Water Filter
Your LG refrigerator water filter plays an important role in removing chlorine, lead, mercury and other contaminants from your tap water. Over time, the filter becomes saturated and loses its effectiveness, which means your drinking water may no longer be truly filtered.
We recommend that you replace your water filter for LG refrigerator every 6 months or after filtering approximately 200 gallons of water, whichever comes first.
Neglecting to change your LG fridge water filter can result in:
- Bad tasting water and ice cubes or odors
- Slower water flow from the dispenser
- Potential buildup of contaminants in your drinking water
- Pressure on your refrigerator’s water supply
Which Filter Fits Your LG Refrigerator?
Choosing the correct water filter model for LG refrigerator is critical for optimal fit and performance. First, read your refrigerator’s owner’s manual. The manual will usually list compatible water filter models. If you’ve lost your manual, open your refrigerator and locate your existing water filter. Most LG fridge water filters have the model number printed on the side or top of the filter. Common LG water filter models are LG LT1000P, LT800P, and LT700P. You can also find the model number on a label inside the refrigerator (usually on the wall or side panel near the vegetable drawer). The label will usually include information about compatible parts. If you’re unsure, search online for your refrigerator model number and type in “water filter” to find the appropriate replacement water filter.
