Factors To Consider Before Selecting The Best Water Filter To Remove Calcium And Lime
At the start of my research for the most effective water filter, I understood that I would have to set up some criteria for the search. It would be impossible to compare one water filtration system to another without being aware of the factors I was assessing.
When deciding on the search criteria, it should be something that will significantly impact the system’s performance, the unit’s efficiency, the quality of the water after filtration, and the user’s satisfaction with the water filter. The criteria I settled on are:
Ability To Remove Calcium & Limescale
Different filters can potentially eliminate varying levels of calcium and limescale from a water system. If you encounter issues with calcium and limescale in your water, the filter’s capability to take out the calcium should be the top priority. Therefore, you should search for a filter that eliminates the most calcium.
Filtration Technology
A broad selection of filtration systems is available, each of which can impact the performance and outcome of water filtration.
An ion exchange procedure removes calcium and magnesium ions from water, switching them with sodium ions. This technique is highly efficient and is employed in several water softeners and filters, reducing the amount of calcium in the water.
Reverse osmosis filters utilize a filter membrane and other filters to push water through them to remove sediment and heavy metals. They are pretty successful in decreasing calcium levels as well. Many think water that has gone through a reverse osmosis filter tastes better than bottled water.
Sediment filters physically separate substances not desired in the water, including calcium. While they are less proficient than other methods, sediment filters are still effective in lowering the calcium levels in the water.
Flow Rate
It is critical to consider the rate of flow of the filtration system. If a whole-house water filter doesn’t allow enough water to meet your family’s needs, it will be more of a hindrance than an advantage.
Certifications And Warranty
Receiving certification from an outside entity, such as the National Sanitation Foundation (NSF), may not directly impact the unit’s operation. Still, it can give people extra assurance that the water filter is of superior quality.
This indicates that the producer is not only asserting that their filtration system functions optimally, but they are also willing to let someone else validate their statement.
A warranty is comparable to a guarantee in certain aspects, as it demonstrates the producer’s assurance in the excellence of their product. The maker believes in their product if a water filter comes with an extended guarantee. This could help you save a lot of money if you experience difficulties.
Price
Price is the last factor to consider. Even though it doesn’t necessarily affect the excellence of the filtration system, if 2 water filters are closely similar in other ways, then you can use their cost as the deciding factor.
The product’s expense should be considered when you have a restricted amount of money. It is not practical to expect everyone to invest a large amount of money, such as 2000 dollars, into a top-notch water softener and filter. Some individuals may be satisfied with paying less than two hundred dollars for a water purifier installed under the sink.

Water Filter To Remove Calcium And Lime Buyers Guide
Calcium is a common chemical element found in almost all water sources. This may be sourced from below the earth’s surface or from the surface, and as the water passes through or over the ground, it obtains minerals such as calcium or magnesium.
Why Is Calcium A Problem?
Most water delivered to households contains small amounts of calcium and magnesium. However, certain water sources, such as from wells, may have excessive amounts of calcium which can result in difficulties.
Most water sources provide households with calcium and magnesium, although some sources may have excessive calcium, causing issues. This is true for water drawn from wells.
If you find yourself with water that has a high concentration of calcium and magnesium, you may want to take steps to reduce it. A great way to do this is to soften the water. It is possible to address this problem by eliminating the calcium or using electromagnetism to stop the calcium from adhering to the pipes.
How do I Remove Calcium And Prevent Limescale?
If you need to get rid of calcium from a small amount of water, boiling is a viable solution. If the water is intended for drinking or cooking, boiling will cause the calcium to settle at the bottom of the pot, leaving you with clear water that can be poured off.
The demerit of this approach is that it is not feasible to maintain the necessary amount to drink it continuously, and it does not offer any form of protection to your pipes. In conclusion, this method cannot be used.
When selecting a filter to remove calcium from your water, you should opt for a 5 micron filter. This type of filter can eliminate a significant number of calcium molecules. A homeowner can use various water filtration systems, such as a whole-house system, a filter installed under the sink, or a pitcher-based filter. However, the only way to guarantee protection for the plumbing is to install a calcium filter or water softener on the entire house.
How Does Calcium Affect Water Quality?
If the calcium level in water is too high, it can adversely affect the water’s quality, changing its taste. Hard water will cause your soaps and detergents to become less effective, so you must use more products and water to remove them fully.
It will also leave ugly marks in places such as your kitchen sink, coffee pot, washing machine, bathtub, and toilet.
When deciding a water filter to remove calcium and lime, consider the above criteria.
FAQs (Frequently Asked Questions) On Water Filter To Remove Calcium And Lime
1. How do you filter calcium and lime out of water?
You can filter calcium and lime out of the water through reverse osmosis. The most effective technique to decrease limescale is using a membrane with tiny holes to allow water to pass through while obstructing chemicals and other dissolved solids, including calcium, magnesium, lead, arsenic, etc.
2. What water filter will remove calcium?
Reverse osmosis can extract 95% to 98% of the calcium molecules in water. Additionally, Electrodialysis and Ultrafiltration can also be used to remove calcium.
3. Does filtering water remove lime?
A practical method of reducing the limescale from your water source is installing a complex or mains water limescale filter. This rearranges the calcium particles, so they no longer create limescale, resulting in water comparable to soft water.
4. Do Brita filters remove calcium and lime?
Brita filters are not capable of eliminating calcium and magnesium. Instead, they work by decreasing the amount of carbonate hardness in the water, thus making the formation of calcium carbonate less probable. Consequently, you can still benefit from the essential minerals.
Summary: Water Filter To Remove Calcium And Lime
I have explained how calcium and limescale can be detrimental to you and your residence and what aspects to consider when looking for calcium water filters.
