inline water filter for ice maker reviews


Can you put a water filter on your ice maker?

You can, but it would also filter all your water that goes into the refrigerator. Also, even though it’s called an ice maker, that’s only part of the water system. It also takes water from the ‘water dispenser’ and sends it to the ice maker. It takes water from an internal tank and/or external line and sends it on.

Does filtered water have more minerals?

No, it has the same amount of minerals as unfiltered water. Minerals are in all water from your tap or bottled water.

Should you filter ice water?

There is some debate on this. Generally, if you plan to eat the ice, there shouldn’t be a problem. However, some people like to collect ice over some time, and the melting ice will re-contaminate.

Is there a difference between drinking water and ‘ice’ water?

Yes, generally ice has fewer minerals than drinking water because it comes out of the ice maker which is a lot less mineralized. There’s a difference between the speed of going from the water dispenser to ice, and then melting it on your tongue which can taste pretty bad if you leave it in the ice bucket. 

What is an inline water filter?

Inline water filters are attached to the pipe system that brings water from your faucet or a whole house filter, from one place to another. Typically, they are used for ice makers.
