This guide focuses on the Waterdrop CLCH121 and CLCH122 refrigerator water filter replacements. These products are crucial for maintaining clean, fresh-tasting water from your refrigerator. They help address common issues like sediment, chlorine, and other contaminants, ensuring healthier drinking water for your household.

Curated by Kitchen Bench · Updated June 2026

Built for home cooks using LG or Kenmore fridges who need a reliable, tool-free replacement for their internal water filters. Not for owners of built-in commercial-grade units—this shop focuses exclusively on the twist-and-lock CLCH series compatibility.

Curator's pick: Water Filter 3-Pack Replacement for LT1000P

The three-pack is the smarter play because once you start cooking with filtered water for stocks and boiling, you'll cycle through these every six months and having a backup on the shelf prevents the panic of a clogged line mid-prep.

⚠ Worth knowing: These filters won't fix a slow flow rate if your water line is already kinked or the actual fridge valve is failing; if your ice cubes are coming out small even after a fresh swap, the issue is your plumbing, not the cartridge.

What works

  • Replacing your refrigerator filter ensures continuous access to clean, great-tasting water directly from your appliance, improving daily hydration.
  • Utilizing compatible filters effectively reduces common tap water contaminants like chlorine and sediment, leading to a healthier water supply for your household.
  • The availability of multi-packs and NSF-certified options provides cost-effective bulk purchasing and verified purification standards, offering flexibility and peace of mind.

What to know

  • Ensuring compatibility with your specific refrigerator model requires a quick check of your appliance's manual or existing filter number to avoid purchasing the wrong replacement.
  • While refrigerator filters improve water quality, they don't replace the need for comprehensive whole-house filtration for all water used in cooking and bathing.

How to use this together

  1. 1

    Identify Your Filter Type

    Before purchasing, locate your current refrigerator filter in your appliance and note its model number (e.g., CLCH121 or CLCH122). This ensures you select the correct replacement filter for seamless installation and proper function.

  2. 2

    Remove the Old Filter

    Turn off the water supply to your refrigerator to prevent leaks. Typically, refrigerator filters twist out or pop out. Refer to your refrigerator's manual for exact instructions, as removal varies by model.

  3. 3

    Install the New Filter

    Align the new Waterdrop CLCH121 or CLCH122 filter with the filter housing and twist or push it into place until it clicks or locks. Do not force the filter. Ensure a snug fit to prevent leaks. The NSF Certified filter will install the same way.

  4. 4

    Flush the New Filter

    After installation, open the water supply and run about 2-3 gallons of water through the refrigerator dispenser. This flushes out air and carbon fines, ensuring optimal taste and clear water. Discard this initial flushed water.

  5. 5

    Reset Filter Indicator

    Most refrigerators have a 'Filter Reset' button or indicator light. Press and hold this button for a few seconds to reset the filter life monitor. This ensures your refrigerator accurately tracks when the next replacement is needed.
