Water is an essential element in our everyday lives. However, not all water is created equal, and the quality of the water you drink and use in your home can significantly impact your health and well-being. Calcium is a kind of mineral that is found naturally in water. It is essential for survival because it helps strengthen bones and teeth, lower blood pressure, and protect against certain cancers.
On the other hand, you might not always want calcium present in regular water from the tap. One of the most common problems in water is the presence of calcium, which can lead to hard water and several plumbing issues. Does whole house water filters remove calcium? In this article, we will explore the effectiveness of whole-house water filters in removing calcium from the water and review the best water filters for calcium removal.
Understanding Hard Water and Calcium
Hard water includes high quantities of minerals such as calcium, magnesium, and iron. These minerals can cause problems such as clogged pipes, water stains, and soap scum buildup. Calcium is one of the most common minerals found in hard water, and its presence can have several effects on water and plumbing. For instance, calcium can cause scale buildup in pipes and appliances, reducing efficiency and causing a shorter lifespan.
To specify if you have hard water and how much calcium is present in your water, you can perform a simple test using a water hardness test kit. These kits are widely available and can provide valuable information on the quality of your water.
Level of Hardness and Softness of Waters
General guidelines for the classification of waters are:
Soft Water:
0 to 60 mg/L (milligrams per liter) as calcium carbonate is classified as soft;
Moderately Hard:
61 to 120 mg/L as moderately hard;
Hard:
121 to 180 mg/L as hard;
Very Hard:
More than 180 mg/L is very hard.
Types of Water Filters
Several types of water filters are available on the market, and each works differently to remove contaminants from water. Regarding removing the calcium, some filters are more effective than others. The most common types of water filters include:
Reverse Osmosis (RO) Systems
Reverse osmosis (RO) systems are one of the most effective forms of water filters for eliminating calcium from the water. These systems employ a semipermeable membrane to filter out minerals and pollutants, leaving only pure, clean water behind.
Water Softeners
Water softeners are another effective way of removing calcium from the water. These systems use ion exchange to replace calcium and sodium ions, making the water soft and minerals-free.
Gravity Filters
Gravity filters are simple and easy to use, and they work by using gravity to force water through a filter to remove impurities. These filters are less effective than RO systems or water softeners at removing calcium but can still significantly improve water quality.
Carbon Filters
Carbon filters work by utilizing activated carbon to extract pollutants from water. These filters are less effective than RO systems or water softeners at removing calcium, but they can still improve water quality.
Factors to Consider When Choosing a Water Filter
When choosing a water filter for your home, there are several factors to consider, such as:
Water Quality
The quality of your water will determine the type of filter you need. If you have hard water with high calcium levels, you may need a more powerful filter, such as an RO system or water softener.
Budget
Water filters come in a wide range of prices, so choosing one that fits your budget is essential. Remember that some filters may have ongoing maintenance costs that should be factored in.
Maintenance
Different types of water filters require different maintenance levels, so it’s essential to consider how much time and effort you’re willing to put into maintaining your filter. RO systems and water softeners require more maintenance than gravity or carbon filters.
Water Usage
The water you consume daily will also determine the filter you require. If you have a big home with heavy water consumption, you may need a more powerful filter to keep up with demand.
