What water filter will remove calcium?

Calcium is an important element for the human body, this mineral is important for life and health. But this mineral in your tap water leaves a lot of lime in the filter system. Water is made up of many different impurities, one of which is calcium. That is why it is so important to buy a filter to remove calcium.

Whole house water filters will help in cleaning surfaces from calcium ions that clog pipes over time.

By removing calcium ions from the water, you extend the life of all appliances in your home.

Also, calcium ions can clog up the entire water supply, and this will create some more water problems and may cause health problems.

What water filter will remove calcium?

If you want whole house water filter, consider buying a good calcium water filter. With the right choice, these systems can also remove other water contaminants and give your family clean and safe drinking water.

Do you want to know how to remove calcium from your water? In this article, you will read about the best calcium-removing water filters and choose the best one for you.

Filter Evaluation Criteria

In order to find a good water filter for removing calcium, it is best to set certain search criteria. As a result, it will be difficult for you to compare one water filtration system with another without knowing what exactly you are comparing with each other.

Search criteria should take into account the efficiency of the device, how well the system purifies water, Also, appearance matters a lot.

Now let’s talk about the criteria that are basic when choosing a filter to remove calcium.

Flow rate

Pay attention to the flow rate of the filter system, this is very important. If enough water is not flowing through the filter to supply your home, it will be more bad than good.

Certificates and warranty

Yes, it is not important for the functioning of the device. But remember that a filtration system certified by an authority such as the National Sanitation Foundation will give you a high quality water filter guarantee.

This certificate says that the manufacturer’s words that his filter system works perfectly, not just words, but proven by third-party organizations in practice.

The guarantee says that the seller is confident in the quality of his product. If you have been given a long warranty, then the seller shows that he is ready to confirm what he is selling.

If in the future you encounter problems, the seller is obliged to help you in solving them.

Filtration technology

We already wrote about them earlier in the article.

There are several filtration systems, and they are of great importance for the operation of the filters and the quality of the water they filter.

  • Ion exchange system. Replaces calcium and magnesium ions with sodium ions. This is the system used in May water softeners and filters.

This technology removes a large percentage of calcium in the water.

  • Reverse osmosis. It pushes water through the filter membrane and other filters, and finally filters out sediment and heavy metals, and also reduces the amount of calcium in the water well.

It is believed that water that has passed through a reverse osmosis water filter tastes better than water in plastic bottles.

  • Sediment filters. They physically remove various water impurities as well as calcium. He is not as good at removing it as other methods.

Ability to remove calcium and lime

Most filters filter some of the calcium and limescale out of your system, but they all remove different amounts. If you are having problems with calcium in your water, then the ability to filter calcium is considered an important aspect of the filter.


This, of course, does not affect the quality of the water after the filtration system. But if two water filters are the same in terms of characteristics, then the price can be a decisive factor. Not every customer can afford to invest $2,000 in a water softener and filter.

How to remove excess calcium from water?

In fact, you will not find special calcium water filters in stores. Some filters are very difficult to remove calcium from hard water. Although most reverse osmosis filters and ultrafiltration membranes can help get rid of calcium in drinking water.

Reverse osmosis system

After such a filtration process, calcium and other unwanted substances are discharged into the sewer along with wastewater.

Reverse osmosis comes with a semi-permeable membrane that has many small holes that collect most pollutants, even calcium.

Reverse osmosis will filter out 92% to 98% of calcium carbonate minerals from your water.

Large calcium particles cannot be filtered through the reverse osmosis membrane and thus enter the osmosis chamber.

Water softener

If you want to reduce the level of calcium in your water, consider treating hard water softener.

Do not confuse a water softener with a filtration system that purifies water. Instead, it takes away some of the hardness minerals, including calcium minerals, and that’s about it.

This method will help you get rid of various yellow stains on some plumbing surfaces.

The water softener does an ion exchange to replace calcium with potassium or sodium. Not only do

Water softener reduce the concentration of calcium, they also completely eliminate water hardness.

Let’s take a look at the benefits of salt-based water softening systems:

  • The water softener will stop the formation of scale and extend the life of: coffee makers, water heaters, dishwashers, etc.
  • You will notice far fewer stains on sinks, dishes and windows.
  • Your water will be much cleaner and easier to make better if it is not calcium-dominated.
  • Your clothes will no longer fade if your water is calcium-free.

The price of a water softener in stores is about 1000-2000 dollars. A good salt-based calcium water filter is worth the money. A water softener is a good thing.


Ultrafiltration will feel familiar to you, it is very similar to a reverse osmosis system. This is process, like a reverse osmosis system, has a membrane filtration process in which the membrane retains contaminant minerals down to 0.01 microns

Of course, ultrafiltration membranes will not be able to contain small elements, like reverse osmosis membranes, but this does not prevent them from catching calcium from hard water.

An ultrafiltration system can remove and purify up to 50% of calcium from drinking water. But be careful when choosing this system, some ultrafiltration methods will not be able to remove calcium from your water. Read the instructions for the manual.

Water conditioner

You need this method if you refuse to add salt to the water, but still want to remove the hardness of the water.

The difference between an air conditioner and a water softener is that air conditioners do not remove calcium from the water, so your water quality will not change.

Salt-free water conditioner is a super perfect way to get rid of calcium. It is a crystallization process, such as patterned crystallization, to prevent hardness minerals from sticking to surfaces and scale formation.

These air conditioners cost about 1500-2200 dollars. They are not as effective at fighting calcium as salt-based systems, but they are more effective than whole house water filter.

Frequently asked Questions:

Can calcium be removed from water with a whole house water filters?

A whole house water filter often uses a multi-stage filtration process to eliminate contaminants and improve the taste and smell of your water.

Please note that if you have a regular whole house water filter, it is not designed to remove calcium from the water!

Many filters have a small rating in microns, therefore, they eliminate only large calcium particles. But to remove calcium from the water completely, you will need auxiliary water softeners. Water softeners are very easy to install.

Why is there calcium in my water?

You most likely live in an area dominated by rocks, including apatite, fluorite, limestone, marble, calcite, gypsum, and dolomite.

Do charcoal filters remove calcium?

Activated carbon filters do not remove calcium. Carbon filters can effectively remove or reduce many water pollutants, chlorine and many others.

If you boil water, will it remove the calcium?

Yes, it can be a solution to remove calcium from water. The boiling method precipitates dissolved minerals such as calcium. Boiling will result in softer water. This is the fastest and cheapest way to get rid of calcium. The calcium filtration efficiency is very high.

Is calcium in the water a problem?

In fact, calcium is not dangerous to health, if too much of it in the water will lead to a number of problems.

  • Due to the water hardness, lime deposits remain on the surfaces in the bathroom.
  • Calcium can cause brittle hair and dry skin. In addition, you can buy dandruff and itching.
  • Accumulation of calcium in the pipes can reduce the flow rate, which becomes a problem and then requires an expensive replacement.
  • The water hardness in the wash will fade the color of the clothes.

How to filter to remove calcium from water?

Soft water and reverse osmosis system are the best water filters that remove calcium from the water. You can also use home remedies to soften hard water:

  • Ion exchange,
  • Water distillation,
  • Boiling water.

Let’s summarize:

The right calcium water filter will get rid of limescale, and keep dishes, plumbing, water heaters, and so on clean. It also protects plumbing fixtures and extends their lifespan.

Choose the best filter for you by considering many factors, to ensure optimal calcium removal without compromising adequate water intake. Drink good quality drinking water.
