The Best LG Refrigerator Replacement Water Filter 2025

If you own an LG refrigerator with a built-in water dispenser and ice maker, keeping your water clean and fresh is essential. A high-quality water filter removes contaminants like chlorine, lead, mercury, and other impurities, ensuring safe and great-tasting water for you and your family.

In this guide, we’ll cover the best LG refrigerator replacement water filters, how to choose the right one, and tips for maintaining your filter for optimal performance.

Why You Need a Quality Replacement Water Filter

Over time, water filters lose their effectiveness as they become clogged with impurities. Using an expired or low-quality filter can lead to poor water taste and potential exposure to harmful contaminants. That’s why replacing your LG refrigerator’s water filter every 6 months (or after 200-300 gallons of water) is recommended.

Look for NSF-certified filters, ensuring they meet safety and quality standards. Avoid generic, unbranded filters that may not properly filter contaminants.
