 LG refrigerator water filter is a nifty yet crucial component ensuring your drinking water is safe and contaminant-free.

This fridge filter uses a multi-stage filtration process to remove chlorine, dirt, and other impurities. 

As water passes through the LG water filter, contaminants are trapped, and cleaner water is dispensed. 

Regular replacement filters maintain optimal filtration performance, ensuring your refrigerator water from the dispenser is both refreshing and healthy.

Key Takeaways

  • LG refrigerator water filters use a multi-stage filtration process to remove contaminants like chlorine, lead, and pesticides.
  • Replace the filter every six months to ensure optimal performance.
  • Installation involves simple steps: remove the old filter, insert the new one, flush with water, and reset the indicator light.

You know the one I’m talking about – the one tucked away on the back left side inside your refrigerator. That’s where all the magic happens.

Raw water enters this filter housing, and from there, it goes through a coconut shell-activated carbon filter.

This isn’t just any filter – it’s a superhero in disguise! It traps and absorbs all sorts of nasties like chlorine, lead, mercury, pesticides, and even pharmaceuticals.

Here’s the breakdown of how it works:

  1. Particle Filtration: First, it catches the big stuff like sediments and debris on the outer surface of the carbon.
  2. Micro-filtration: Then, it grabs medium-sized contaminants like sugars and cysts as the water flows through the carbon.
  3. Absorption-filtration: Finally, it deals with the tiny pollutants. The carbon chemically absorbs these microscopic bad guys, making your water taste and smell better.

Once the water is squeaky clean, it flows through your fridge’s water dispenser and ice maker, giving you fresh-tasting water and ice. But remember, this filter isn’t eternal. About every six months, a little light on your control panel will let you know it’s time for a change.

When it’s replacement time, here’s the lowdown:

  • Turn the old filter counterclockwise to remove it from the filter head.
  • Pop in the new one, align the tabs, and turn it clockwise to lock it in place.

  • Don’t forget to run about 2.5 gallons of water through the new filter to flush out any air or leftover contaminants.
  • Finally, press and hold the Water Filter button on the control panel for 3 seconds to reset that pesky indicator light.

Now, if you’ve got an LG fridge, there’s some extra cool stuff you should know.

LG uses different filtration methods depending on the product:

  • LG water purifiers use a multi-stage reverse osmosis (RO) system. This baby removes contaminants as tiny as 0.0001 micrometers – we’re talking bacteria, viruses, and heavy metals.
  • LG refrigerator water filters use an Ultra Filtration (UF) filter. This one gets rid of bacteria and harmful substances but keeps the good minerals like calcium and magnesium.

LG also recommends swapping out your fridge water filter every six months. Some signs that it’s time to replace include:

  • The water tastes or smells off
  • You see black specks or debris
  • The water looks cloudy
  • The water filter light turns on

Fact: LG LT700P filter is NSF certified to cut down on stuff like chlorine, lead, pesticides, and VOCs. Pretty cool, right? You can totally use third-party replacement filters too, like the Neo-Pure LT700P.

Ever wonder how an LG water filter works? Well, let’s break it down! In your LG French door refrigerator, the refrigerator filter handles tap water like a boss.

To keep things fresh, it’s recommended to replace the filter every 6 months. The carbon in the filter really does wonders for water quality by removing impurities, so it’s crucial that you don’t skip out on replacing the filter.

If you’re curious about how these refrigerator water filters work, know that when you replace your water filter, the new water filter takes on the job of purifying your whole house water system that flows through the fridge.

The filter cartridges are the heroes, ensuring your hydration game is on point. Forget about it, and you might need that bypass plug temporarily.

Even the air filter plays a role in keeping everything fresh. If you’re not sure about replacement water, just check out the LG USA support site or contact us directly.

For specific steps, always check your refrigerator model‘s manual on how to replace water filter or consult with an expert to ensure those filters really work to improve your water system.


How do LG refrigerator water filters work?

LG refrigerator water filters work by pushing water through a dense carbon block, which filters out impurities like chlorine, lead, and other contaminants. This ensures you get clean and safe water for drinking and cooking.

How often should I replace the water filter in my LG refrigerator?

You should replace the water filter in your LG refrigerator approximately every six months. If you notice the water pressure from your water dispenser noticeably decreases, it might be a sign that you need a new filter sooner.

Can I use any brand of water filter for my LG refrigerator?

It’s best to avoid using non-LG brand water filters. Using quality refrigerator water filters specifically designed for LG devices and appliances ensures optimal performance and water filtration.

How do I install a new water filter in my LG refrigerator?

To install a new water filter, locate the filter housing inside your refrigerator, remove the old filter by twisting it counterclockwise, and insert the new filter by twisting it clockwise until it’s snug. Always consult your refrigerator model’s manual for specific instructions.

What contaminants do LG refrigerator filters really remove?

LG refrigerator filters remove a wide range of contaminants including chlorine, lead, mercury, and particulates. They help ensure that your water for drinking and cooking is safe and clean.

Why has the water pressure from my water dispenser decreased?

If the water pressure from your water dispenser noticeably decreases, it usually means it’s time to replace the water filter. Over time, the filter can become clogged with contaminants, reducing water flow.

Are there any adverse effects if I use my LG water filter for more than recommended?

Yes, using your water filter for more than the recommended time can lead to reduced water quality and flow. The filter cleans less efficiently, and more contaminants may be left in the water.

Is there anything else I should know about LG water filters?

Always make sure you match the water filter to your specific refrigerator model number for proper fit and operation. If you need help, don’t hesitate to contact us for support and potential replacement parts.

Can I use a water distiller instead of a refrigerator filter?

While a water distiller can also purify water, it may not be as convenient as using a refrigerator water filter for everyday use. Refrigerator filters offer immediate access to clean water directly from your fridge.

Why is advanced water filtration important for my refrigerator?

Advanced water filtration is important because it ensures you and your family have access to clean and safe drinking water. LG water filters work effectively to remove harmful contaminants, providing peace of mind.
