Glacier Fresh GF-1000P Compatible with LT1000P Refrigerator Water Filter, 3-Pack

Coconut shell activated carbon is widely considered the highest quality carbon source for water filtration. Compared to coal-based carbon, coconut shell carbon has a higher surface area and more micropores, which means better adsorption of chlorine, taste, odor, and organic contaminants. The GlacierFresh GF-1000P uses 100% Sri Lanka-selected coconut shell charcoal block — the same premium material used in high-end filtration systems — and is BPA-free and food-grade certified.

A 3-pack is excellent value for most households. Unopened filters have a shelf life of 2–3 years when stored in a cool, dry place away from direct sunlight and strong odors. Since each filter lasts 6 months, a 3-pack covers 18 months of filtration — well within the shelf life. You'll save money per filter and avoid the hassle of reordering every 6 months.

The GF-1000P uses a three-stage filtration process within the carbon block: first, a pre-filter layer captures larger sediment and rust particles; second, the coconut shell carbon block adsorbs chlorine, chemicals, and organic compounds; third, a post-filter layer catches any remaining fine particles before water reaches your glass. Importantly, the filter is designed to reduce harmful contaminants while retaining beneficial minerals like calcium and magnesium that your body needs.

Leaking from third-party filters is almost always caused by imprecise tolerances in the filter housing. The GlacierFresh GF-1000P is precision-engineered to match OEM dimensions exactly — the O-rings and housing geometry are designed for a watertight seal with no modifications. If you experience any dripping after installation, the most common fix is to remove the filter and reinstall it, ensuring it's fully twisted clockwise until it clicks firmly into the locked position.

It works with both. Kenmore refrigerators sold under part numbers 46-9980 and 9980 use the exact same filter as the LG LT1000P — Kenmore sources many of its refrigerators from LG. The GlacierFresh GF-1000P is a direct replacement for both brands with no modifications needed.

The GF-1000P carries three independent certifications: NSF/ANSI verifies contaminant reduction performance and material safety; IAPMO (International Association of Plumbing and Mechanical Officials) is an accredited third-party testing body that validates the NSF claims; and ISO certification confirms the manufacturing facility meets international quality management standards. Together, these mean the filter's performance claims are independently verified — not just self-reported by the manufacturer.

Slow flow after a new filter installation is almost always caused by trapped air in the filter. This is completely normal and easy to fix: continuously dispense water for 3–5 minutes to purge the air pocket. Also make sure to run and discard at least 2 gallons to flush the new filter before drinking. If flow remains slow after flushing, double-check that the filter is fully locked — a partially seated filter restricts water flow significantly. If the issue persists, contact our support team.

After installing the new GF-1000P, press and hold the "Filter Reset" button on your fridge's control panel or dispenser for 3–5 seconds until the indicator light turns from red to green or turns off. On some LG models, the button may be labeled "Reset" or found inside the fridge near the filter housing. The fridge does not auto-detect a new filter — you must manually reset it every replacement cycle.
