You pour a glass of water from the fridge dispenser. You expect it to be clean and fresh.. Have you ever wondered what that little cartridge inside the fridge is actually doing? Is it really making the water clean. Is it just making it taste better? The answer is somewhere in between. A refrigerator water filter has a job but it also has some real limitations. Lets break it down so you know what you are getting.
What Your Fridge Water Filter Is Actually Designed to Do
The job of a refrigerator water filter is to make the water and ice from your fridge taste better. It uses carbon to catch things like chlorine and sediment that make the water taste bad. This makes the water and ice from your fridge taste cleaner. Smell fresher. For a lot of people this is the reason they use the filter. They want their water to taste good.
What It Doesn’t Remove. Why That Matters
There are some things that a fridge filter cannot do. It is not designed to remove things like fluoride nitrates or heavy metals like lead. These are things that the carbon filter's not good at catching. So if you only use a fridge filter you might not be getting the water you think you are. This is important to know.
The Problem with the Fridge Water Dispenser
The dispenser on your fridge can also be a problem. If the filter is old or clogged the water can start to taste. Even if you have a filter the dispenser can still get dirty. Make the water taste bad. This is something to think about.
Why a Whole House Filtration System Wins
If you want water for your whole house you might want to consider a whole house filtration system. This will make sure that all the water in your house is clean not the water from the fridge. These systems are more expensive. Need more maintenance.. They are a good option if you want clean water everywhere.
Better Drinking Water with Reverse Osmosis Filtration
There is also something called reverse osmosis filtration. This is a way to get clean water. It uses a membrane to remove all the bad things from the water. It can be expensive. It can also remove some of the good things from the water.. It is a good option if you want really clean water.

Don’t Settle for Half-Filtration
