The Best Water Filter for Softened Water

Hard water contains high levels of calcium and magnesium compounds. It’s not sweet when drinking and will damage your pipes and appliances.

Though these compounds are helpful to the body, consuming them in high amounts will lead to health complications in the long run. To be specific, water that contains more than 7 GPG of calcium carbonate compound is considered hard.

This raises the need to carry out a purification procedure to lower these levels and soften your water.

By softening your water, you are left with other minerals such as sodium and potassium at a high level. Softened water is fine to drink though it will taste salty due to the raised levels.

Additionally, the amount of sodium in the softened water will determine its safety. It is said that a gallon of soft water has the same amount of sodium as a slice of bread. A hardness level of above 400PPM in your water means that after softening, the level of saltiness will be higher than is needed, and you should avoid it.

This is why you need the best water filter for softened water.

And that’s what this detailed review will provide.

Let’s get started

Factors to Consider When Buying a Filter for Softened Water

1. Water Quality

Before acquiring the filter, consider having your water tested in a reputable lab. This will guide you on the best filter to acquire, guided by the impurities in your water.

4. Space Available

Most salt-free water softeners such as the RO units will take up most of your space. It’s important before you make your purchase to evaluate the space you have for the filter.

5. Compatibility

When buying a filter, go for one that fits well with your already existing plumbing works. Avoid incurring more costs in modifying your plumbing works.

Check the ports’ diameters to ensure that they don’t reduce the feed water’s pressure. The inches of the connectors should match those of your already existing plumbing works.

6. Water Usage

The amount of water you need for daily use in your home will affect the filter you settle for. You need to keep your family consistently supplied with pure water. The filter you buy should be in a position to meet this need.

7. Purification Technology

Water softeners can utilize different filtration methods to purify your water. Depending on your water quality and the functions you intend the filter to perform will affect your choice.

8. Maintenace Cost

Depending on your water supply and quality, the frequency with which you replace filters, membranes, and cartridges will be affected.

As you buy the filter, check out the amount of filtered water it produces in its active life. A filter that can not go for up to 6 months can be expensive to maintain.

For RO membranes, go for the one that can serve you for more than a year, especially because they are expensive and delicate.

9. Ease of Installation

You don’t want to incur extra costs involving a professional plumber during installation. Buy a filter you can effortlessly install.

10. Certification

11. Water Wastage

Go for a filter that allows minimal to zero water loss. You don’t want to be paying high water bills just because you invested in a filter. If you choose to go for a RO purifier, buy one that can accommodate a permeate pump. This will mitigate the high water loss risk common with the RO units.
