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

If you are looking to buy a water filter to remove calcium form your water supply, there are a few prime factors that you may need to give a serious thought to. 

Point of use 

Point of use is yet another factor that you would find quite important and essential to look forward to. Most of the filters belong to the whole house water filter category and help you in providing an effective calcium filtration. 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.

You would notice that there are white stains on the kitchen and bathroom fixtures. The limescales are the build up of calcium carbonate. 

Hair and skin

If your water has too much of calcium, it may impact your hair and skin adversely. Your hair can begin cracking and crinkling. Your skin can become itchy and scratch. 

Water pressure 

Limescale buildup in your fixtures and plumbing can cause the water pressure to increase. This can further harm your plumbing and even your appliances such as heaters. 

Issues with laundry

The issues with laundry can be yet another reason that you need to worry about if your water supply has too much calcium. The hard water will never provide lather. Your laundry may begin fading.

How Does Calcium Affect Water Quality?

The high amount of calcium in water can affect your overall water quality. It can affect the taste of water in many cases. The calcium in water can also affect the effectiveness of soaps and detergents. You will be forced to use more water and more soaps for rinsing away the debris in your water supply. 

The calcium in water leaves stains in the sinks. It can also leave stains on the coffee pots, washing machines, showers, and toilets. That is exactly why it is recommended to pick the right type of water filter or softener for cleaning the water and remove the calcium concentration. 

The Closing Thoughts

The calcium or limescale can prove to be quite effective in causing severe damage and can also create problems for your plumbing system. The filter and water softener combo used cleaning up the water and removing the calcium build. 


Do carbon filters remove calcium?

The activated carbon filters are not capable of removing the contaminants such as sodium, calcium, chloride, nitrate, and fluoride. However, some carbon filters with the advanced technology can also be helpful in filtering out the lead, mercury, and copper.

How to remove calcium and magnesium from water?

If you are looking for the best options for the calcium inhibitor, using the water softeners and reverse osmosis filters would be the right picks to go with. A few other options that you would find quite interesting can include ion exchange, water distillation, and boiling the water

How long do calcium and lime filters last?

The whole house filters would generally last a lifetime of around 10 to 15 years. That would be the right option if you are taking a good care of the filter and softener. The lifetime of the smaller units can be a little different. The under sink filters would last around five to seven years. Even the countertop models should last the same period. 

Does a Whole House Water Filter Remove Calcium?

Yes, whole house water filter system should be able to remove calcium. This would be possible if the filtration membrane is equipped with the ability to eliminate the calcium and other such fine elements.
