They reduce unwanted minerals, such as calcium and magnesium, that can cause hard water and scale buildup in plumbing systems. However, they require regular maintenance, such as changing the filter regularly. A clean Kenmore water softener filter is essential for the optimal performance of your home’s water softening system.

Kenmore water softener filters are designed to remove impurities from the water supply. This can help improve the taste and smell and even reduce staining on surfaces in your home from hard water. These filters remove hardness ions like magnesium and calcium from your water supply, which helps stop scale buildup throughout your plumbing system.

The filter also has the added benefit of removing other impurities like iron, manganese, and sediment from your water supply. This can reduce staining on surfaces and reduce discolouration in clothing when washing.
