Buying Guide For Best Water Filters To Remove Calcium Or Lime

Here is the complete guide after reviewing products in that category of calcium water filters

What is Calcium in Drinking Water?

Calcium is a mineral found naturally in bones and also in nature. When water flows in nature, it gathers many minerals, including calcium, calcium carbonate, and magnesium, which cause hard water and damage your home plumbing and appliances. According to the WHO, Water with calcium carbonate at concentrations below 60 mg/l is generally regarded as soft water; 60–120 mg/l is considered moderately hard; 120–180 mg/l is regarded as hard

Too much calcium consumption can also cause adverse effects on your overall health and cause heart and skin diseases. You mustn’t take more than 3mg of calcium in your water intake. Most of the Calcium and magnesium in water come from sedimentary rocks, and the most common are limestone and chalk.

Small water supplies often encounter significant hardness levels in the groundwater, but some larger surface water supplies also have the same issue. Calcium concentrations up to and exceeding 100 mg/l are standard in natural water sources, especially groundwater. Magnesium is present in natural groundwater, usually at
lower concentrations (from negligible to about 50 mg/l and rarely above 100 mg/l), so
calcium-based hardness usually predominates.

Why is it essential to remove Calcium from Drinking water?

Point-of-entry ion exchange (water softener) filters are used in some households to remove hardness (Calcium, magnesium) and iron from water. Softening the water will have several aesthetically beneficial effects inside the home, such as reducing scaling in pipes, fixtures, washing characteristics, water heaters, and improving laundry, e.g., using a non-precipitating water conditioner. Still, it also increases the level of sodium in drinking water. Point-of-use reverse osmosis and water distillers remove all the minerals from the water, functioning as a final barrier against potential trace-level contaminants that may be present and removing nutrients. In comparison, the water doesn’t need to be conditioned.  If materials not subject to corrosion are used after the treatment, the resultant drinking water is deprived of all minerals.

The use of these devices may reduce the overall intake of nutrient minerals by the consumers in the households. These devices should be made aware of mineral composition changes and the possible consequences for total nutrient intake and human health.

For example, those who sell or install these devices may be encouraged to bring the buyers of these devices to the attention—the possibility of reduced intake of minerals and various means for their replacement.
Additionally, the manufacturers of these filters and devices may provide a suitable bypass of a portion of this water to maintain some level of these minerals in the water consumed (e.g., to a kitchen tap) or develop and add an appropriate remineralizing unit in the water line before the point of consumption. 

Effects of calcium on health:

  • Our body needs calcium for strong bones and maintaining a healthy heart, muscles, and nerves. Our bones and teeth contain 99% of calcium.
  • Calcium is stored in the bones as a reserve and is released when needed. The amount and concentration of calcium in our body decline with age because we lose calcium through sweat, skin cells, and waste.
  • People with low calcium levels can have muscle weakness, twitching, weak and brittle bones, osteomalacia, osteoporosis, and low vitamin D. Calcium supplements are sometimes taken by mouth to maintain calcium levels and reduce parathyroid calcium with hyperparathyroidism and reduce the symptoms of PMS.
  • Drinking high calcium water also has risks. If you have too much calcium in your bloodstream, it can cause hypercalcemia. High levels of calcium can also increase the risk of heart attack and cardiovascular diseases. Calcium intake in high amounts can also cause constipation, diarrhea, and abnormal muscle twitching.
  • According to the US National Library of Medicine National Institutes of Health, high calcium drinking water can cause cardiovascular diseases in some evidence.

Five Best Hard Water Solutions to Remove Calcium

Calcium is an essential mineral, although people ask does water filters remove calcium. So, the answer is yes. Here, we will discuss some of the best mechanisms to remove the extra calcium content and limescale from the hard water. These are simple home remedies to know how to filter calcium from the water. 

Ion-Exchange Resin

This process involves attaching a filter water softener to your water supply. The filter water softener contains resin beads responsible for attracting complex water ions to remove hard water and release sodium ions, making the water soft. A filter water softener uses these ion-exchange methods to replace calcium and magnesium ions with sodium ions. 


Distillation is a very effective hard water softener home remedy for water softening. As the water is heated, it leaves the hard water residue behind. This process is effective for a small quantity of water but not for hefty amounts of water consumption. Energy is utilized to maintain soft water, which increases the cost of drinking water and your electrical bill.


The molecules that easily bind to metal molecules are called chelators. Chelating agents in the water can easily bind to calcium and magnesium and remove hard water. These substances are added to shampoos and detergents for commercial use.

Reverse Osmosis Water Filters

Reverse osmosis water filters are the best water filters for removing calcium and magnesium. Reverse osmosis filters purify water by a semi-permeable membrane and remove 99% of the contaminants, including minerals that make the water hard. The advantage of reverse osmosis is that it does not add minerals back to the water, so you don’t have to worry about your water being soft after reverse osmosis. All you get is purified water, which is healthy to drink.

Reverse osmosis systems effectively remove TDS levels present in countertop RO filters, Undersink RO filters, and whole-house water filters that you can install in your homes.

People with a well water supply want to choose their best system and have a question in their mind: What is the best water treatment system for well water calcium? Due to my experience and research, I will suggest the best system, a whole house water filter that removes sediments and calcium plus reverse osmosis, will be a fantastic choice. 

Water Softeners

A softener water filter is the best calcium filter that removes water hardness. It gives the same effect as chemical treatments without adding any harmful substances to your water supply. A filter water softener is a device that replaces calcium and magnesium with sodium ions that change the structure of the water.

Water Softeners use ion exchange technology for ion removal to lessen the amount of hardness (Calcium, magnesium) in the water; they can also be designed to remove iron and manganese, heavy metals, some radioactivity, nitrates, arsenic, chromium, selenium, and sulfate. They do not remove protozoa, bacteria, and viruses. Such a softener water filter has made life easier.

Factors To Consider Before Choosing The Best Water Filters To Remove Calcium

There are many things to consider while choosing the right water filter to remove calcium from drinking water.

Point of use

A point of entry is significant when choosing the best water filter to remove calcium. Most point-of-use water filters are whole-house water filters attached to the water fixtures and provide calcium filtration.

I will also suggest my loving people go for the best filter to remove calcium from water in the shower to protect their skin and hair from hard water or high calcium water for the whole house water supply.

Filtration Capacity

If we say we need a 100% pure output, your thousands of searches could not find the proper solution. But if you are looking for the best water filter for removing calcium from water is a good query. Whatever the water filter system we Inspect, Check out that it can filter out heavy metals, excessive ions, dissolved solids, sediments, organic matter, and microorganisms. Plus, while making a purchase, also keep in mind to consider the capacity of the system.

Capacity may vary according to consumer choice and demand. Verify whether the system first whether it is eligible to fulfill your requirements of household needs or not. It is crucial to see the filtration capacity for choosing the best water filter for removing calcium. If you want a filter to make coffee, reverse osmosis filters are the most accessible and economical filters to use if you want filtered water with the best option. A whole-house water filter is the best option if you want calcium-free drinking water water for your whole house. 

Filtration Technology

For the 100% removal of calcium and other contaminants, we must choose the most advanced filter technologies, like a reverse osmosis water filter. The best product and filter for removing calcium and magnesium is a polyphosphate-impregnated resin bed. In simple words, phosphates bind to the calcium in the water and remove it.

Calcium Filtration

Consider the best water filter that removes calcium if your running water has a high content. Some water filters, like Frizzlife Wa99, remove 99% of calcium, while others do not. My priority to suggest is reverse osmosis technology used in the filters because it’s my right to tell you what is best or what is not.

Unfortunately, many manufacturers do not give complete information about the calcium-removing properties of the filters. Hence, it is upon your shoulders to do intense research before investing in your water filter.


Many consumers who buy calcium filters are sure to buy NSF or WQA-certified water filters. Certified filters are top-quality premium filters tested by third-party authorizations, which means that the water filter claims are 100% authentic. It would help if you always opted for the best water purifier for calcium removal, NSF/ANSI or WQA certified. 


The best iron and calcium water filters give heavy, mineral-free drinking water, prevent limescale formation, and protect your appliances from corrosion and scale formation. Hard water stains are also adamant about being removed from the places where hard water is constantly in use.
