Why External Water Filter For Refrigerator is Necessary

From my experience, having an external water filter for my refrigerator has been a game-changer. I realized that even though my refrigerator has a built-in filter, it doesn’t always catch all the impurities. An external filter adds an extra layer of protection, ensuring the water I drink and use for ice is much cleaner and healthier.

Also, I found that external filters often have a higher capacity and better filtration technology. This means fewer filter changes and consistently better tasting water. It gives me peace of mind knowing that contaminants like chlorine, sediment, and even some heavy metals are being effectively removed before the water reaches my fridge.

Lastly, installing an external water filter has saved me money in the long run. Instead of relying solely on bottled water or frequent filter replacements inside the fridge, this setup is more economical and eco-friendly. Overall, it’s a simple upgrade that significantly improved the quality of my household water.

My Buying Guides on External Water Filter For Refrigerator

When I decided to improve the quality of the water from my refrigerator, I realized how important it is to choose the right external water filter. Over time, I’ve learned a few key things that helped me pick the best option, and I’m sharing them here to help you make an informed decision.

Why Choose an External Water Filter?

I found that many refrigerators either don’t come with a built-in filter or the existing one isn’t effective enough. An external water filter can enhance water taste, remove impurities, and protect your appliance from sediment buildup. It’s also easier to replace and maintain compared to internal filters.

Types of External Water Filters

There are several types I came across:

  • Carbon Filters: Great for removing chlorine, bad taste, and odors.
  • Reverse Osmosis (RO) Systems: More advanced, they remove a broader range of contaminants but may require more installation effort.
  • Sediment Filters: Ideal if your water has a lot of particles or rust.

I chose based on my water quality and the level of purification I needed.

Key Features to Look For

When shopping, I focused on these aspects:

  • Filtration Capacity: How many gallons can the filter handle before needing replacement? I picked one with a capacity that fits my household’s daily water consumption.
  • Compatibility: It’s crucial that the filter fits my refrigerator model. Many filters specify compatible brands and models, so I checked this carefully.
  • Installation Ease: I preferred a filter that was easy to install without professional help. Some come with clear instructions and all necessary connectors.
  • Filter Life and Replacement Cost: Longer filter life means fewer replacements and less hassle. I also considered the ongoing cost of replacement filters.
  • Certifications: Filters certified by organizations like NSF/ANSI give me confidence about their effectiveness and safety.

Installation Tips

When I installed my filter, I made sure to:

  • Turn off the water supply first.
  • Follow the manufacturer’s instructions step-by-step.
  • Check for leaks after installation.
  • Flush the filter as recommended to remove any initial carbon dust or impurities.

Maintenance and Replacement

Keeping the filter in top shape is essential. I set reminders to replace the filter according to the manufacturer’s timeline, usually every 6 months or after filtering a certain number of gallons. Regular replacement ensures water quality and protects my fridge’s water dispenser and ice maker.

Final Thoughts

Choosing the right external water filter for my refrigerator made a noticeable difference in water taste and quality. By considering the type, compatibility, capacity, and certifications, I was able to find a filter that fits my needs perfectly. I hope my experience helps you select the best option for your home too!
