Why Changing Your Refrigerator’s Water Filter Matters

Water filters trap impurities such as chlorine, lead, sediment, and other contaminants. As the filter works, it gradually becomes clogged with these particles. When a filter is overdue for replacement, several issues can arise:

• Reduced water flow: A clogged filter slows down water dispensing and ice production.

• Poor taste and odor: Contaminants can pass through an old filter, affecting water flavor.

• Potential health risks: Overused filters may no longer effectively remove harmful substances.

• Damage to the refrigerator: A blocked filter can strain the water system, leading to malfunctions.

  
  

Replacing the filter on time keeps your water tasting fresh and your refrigerator running smoothly.

How Often Should You Change the Filter?

Most refrigerator manufacturers recommend changing the water filter every six months. This timeframe balances effective filtration with practical maintenance. However, the exact replacement schedule depends on several factors:

• Water quality: If your tap water contains more impurities, you may need to replace the filter more often.

• Water usage: Larger households or heavy water drinkers may wear out filters faster.

• Filter type: Some filters have different capacities and lifespans depending on their design.

  
  

Check your refrigerator’s user manual for specific guidance. Many models include a filter indicator light that alerts you when it’s time to replace the filter.

Signs You Need to Replace Your Water Filter

Besides following the recommended schedule, watch for these signs that your filter needs changing:

• Water tastes or smells strange: A noticeable chlorine or metallic taste indicates the filter is no longer effective.

• Slow water flow or ice production: Reduced output can mean the filter is clogged.

• Cloudy or discolored water: This suggests contaminants are passing through.

• Filter indicator light is on: Many modern refrigerators have built-in reminders.

  
  

If you notice any of these signs before the six-month mark, replace the filter immediately to avoid water quality issues.

How to Replace Your Refrigerator Water Filter

Replacing the water filter is usually a simple process. Here’s a general guide:

1. Locate the filter: It’s often inside the fridge compartment or at the base grille.

2. Remove the old filter: Turn it counterclockwise or press a release button, depending on your model.

3. Install the new filter: Align it properly and turn clockwise until it locks in place.

4. Flush the system: Run water through the dispenser for a few minutes to clear air and loose carbon particles.

5. Reset the filter indicator: Follow your refrigerator’s instructions to reset the reminder light.

   
   

Always use filters recommended by your refrigerator’s manufacturer to ensure compatibility and performance.

Tips to Extend Your Filter’s Life

While regular replacement is necessary, you can take steps to maximize your filter’s lifespan:

• Use a water softener if your water is very hard, as minerals can clog filters faster.

• Keep the fridge clean to avoid dust and debris buildup around the filter area.

• Avoid excessive water use from the dispenser when possible.

• Store water properly to reduce contamination risk.

  
  

These habits help maintain filter efficiency and water quality.

What Happens If You Don’t Change the Filter?

Ignoring filter replacement can lead to several problems:

• Contaminated water: Harmful substances may pass through, posing health risks.

• Appliance damage: Blocked filters can cause leaks or damage to the water system.

• Unpleasant taste and odor: Water and ice may become unpleasant to consume.

• Reduced ice production: Ice makers may slow down or stop working.

  
  

Regular filter changes protect your health and your refrigerator’s functionality.

Choosing the Right Replacement Filter

Not all water filters are the same. When buying a replacement, consider:

• Compatibility: Use filters designed for your refrigerator model.

• Certification: Look for NSF/ANSI certifications, which ensure the filter meets safety and performance standards.

• Filter lifespan: Some filters last longer but may cost more upfront.

• Filtration capabilities: Check which contaminants the filter removes.

  
  

Using the right filter guarantees clean water and protects your appliance.

Save money and help the environment by regularly replacing your refrigerator's water filter!

While replacement filters average $70–$80 for two per year, the benefits are significant. Over the course of a year, using two filters allows your refrigerator to purify enough water to equal about 3,000 plastic bottles. This saves you over $600 compared to buying bottled water, and it reduces plastic waste in landfills.
