If you’re looking for the best calcium water filter, then you’re in the right place!

Water contains many minerals from the earth, including calcium and magnesium, which makes the water hard, leading to limescale formation on tap and other instruments.

Among these minerals, calcium is an important element.

Though calcium is important for drinking water, the availability of calcium causes the white shot or films in your dishes and shower.

Calcium and magnesium contaminated water leads to hardness in water, which can damage your hair, skin, nails, and clothes during laundry.

So, calcium becomes a problem for daily chores, and so it becomes necessary to remove calcium and magnesium by using water softeners.


10 Best Calcium Water Filters Reviewed And Rated

With that said, let’s get started with our list.

Here are the 10 best calcium water filters and their reviews.

1. Home Master 20 Micron Replacement Filter

After water filtration, water temperature remains up to 40-100 degree Fahrenheit (F) that means filtered soft water will never be too hot or too cold for the user.

We all have ideas about the pH levels of water.

pH level indicates whether the water is acidic or basic.

Water with a pH level greater than 7 is considered basic and less than 7 is acidic.

The lesser the number of pHs, the more acidic, and the more the value of pH, the more it acts as a base.

In both cases, water becomes harmful to the skin.

This filter keeps pH to a minimum (pH 4-10) so that skin is safe.

How can you describe a filter’s quality?

It’s by the number of minerals and dissolved solids in the water.

In the case of this filter, it’s almost 2000 ppm.

This is quite a number that indicates that your water is now safe to use.

Pros & Benefits:

  • The coconut shell activated carbon of this filter serves you with a better smell, taste, and a perfect purification

How To Remove Calcium From Water?

Majority of hard water is calcium.

The calcium and magnesium ions from hard water can be removed by using water softeners.

Water softener works on the principle of ion exchange, in which calcium and magnesium ions are exchanged with sodium or potassium ions.

This ion exchange reduces the concentration of hardness causing minerals and smoothens the hard water, making it comparatively softer and friendlier for consumption and use.
