Quick Take

• What it is: 2-pack combo (1x refrigerator water filter + 1x fridge air filter)

• My verdict: 4.7/5 — fantastic value, easy install, and noticeably better water taste and fridge freshness

At a Glance

• Certifications: NSF 42 (chlorine, taste & odor), NSF 372 (lead-free materials)
• Filter media: Coconut shell carbon block from Sri Lanka (large surface area, more micropores)
• Lifespan: Up to 6 months or 200 gallons (varies by water quality and usage)
• Includes: Monthly install reminder stickers
• Also called: Waterdrop F46 (replacement for LG LT1000P/MDJ64844601)

Filtration Performance You Can Taste

Waterdrop’s coconut shell carbon block is the star here. Compared to common charcoal blends, it has more micropores to capture impurities and improve taste.

• Reduces: Chlorine, taste and odor, turbidity, rust, and sediment
• Independently tested to reduce: Heavy metals like mercury, copper, cadmium; VOCs; chromium; THMs; and other suspended particles
• Materials: BPA-free housing; NSF 372 lead-free certified

The result is crisp, clean water that tastes better for drinking, coffee, and ice.

Water Filter vs. OEM: How It Stacks Up

• Taste: On par with OEM in most fridges after the initial flush
• Certifications: NSF 42 and 372 match typical OEM standards
• Price: Usually significantly cheaper than LG-branded filters
• Extras: Monthly reminder stickers and included air filter are great bonuses

Air Filter (LT120F) = Fresher Fridge

The included LT120F-compatible air filter helps trap odors from onions, leftovers, and strong cheeses so your fridge smells clean. Replace it about every 6 months for best results.

Installation Tips (Easy, 5–10 Minutes)

Water filter (LT1000P style):

1. Turn off the water supply if needed (check your fridge manual).
2. Open the filter housing and remove the old filter.
3. Insert the new filter until it clicks/locks.
4. Flush 2–3 gallons of water to clear carbon fines and prime the filter.
5. Reset the filter indicator and place a monthly sticker as a reminder.

Air filter (LT120F style):

1. Open the air filter cover (usually in the back panel inside the fridge).
2. Remove the old filter; snap in the new one.
3. Close the cover and reset the air filter timer if your fridge has one.
