Should Your Water Filters Remove Calcium?
The water filters are designed to remove the contamination based on the size. You would find the calcium ions to be extremely small to be caught by the water filters. In most of the scenarios, using a water softener may not be able to remove the calcium ions from your plumbing system.
The best option that can help you remove the calcium can be to make use of the Reverse Osmosis process. This method involves the use of a semi-permeable membrane. This type of system is capable of taking care of the contaminants such as trap calcium, magnesium, and numerous other particles.
Yet another excellent option that can be helpful in addressing the calcium in the water supply can be to use water softener. The water softener is used for stripping the hard minerals, such as calcium and magnesium, from your water supply.
Where Does Calcium Come From?
The calcium in the water comes due to the leaching of rocks. Most of the calcium in the surface of the water comes from the streams of water that flow over limestone, dolomite, gypsum, and other calcium-containing rocks and minerals.
Calcium is naturally present in the water. It may be found in the dissolved form in the rocks, limestone, marble, calcite, dolomite, gypsum, fluorite and apatite. When we tap these rocks for water, the water will degrade the rocks and will dissolve the calcium in it. it will eventually make its way into our drinking water.
Factors To Consider Before Choosing The Best Water Filters To Remove Calcium

Point of use
Point of use is yet another factor that you would find quite important and essential to look forward to.

As a water technology expert myself, I did put a host of water softeners and water filters to test and found the whole water systems a good pick to choose in most of the scenarios.
Filtration capacity
The ability to filter out heavy metals, excessive ions, dissolved solids, sediments, organic matter, and microorganisms should be a few factors that you would find quite important. The exact capacity will largely be dependent on the amount of water you use and other factors that would be individual in nature.
Ability to filter calcium
The ability to filter calcium should be prime factor that one needs to consider. If your running water has a very high degree of calcium content, it should be important to look for the capability to filter the calcium. It may be a good idea to check if your filter can filter out 99% of calcium.
Certification and warranty
The certification and warranty may not affect the functioning of the water filter. A filter certified by the third party authority such as the National Sanitation Foundation (NSF) should help you in providing more confidence bout the quality. The certification is a good way to indicate the better success rate.
Filtration technology
You must check out which filtration technology is being used in the filter you are buying. Because different types of water need different filtration treatment.
