This results in noticeably softer water, which prevents limescale buildup and can improve the feel and taste of the water. However, water softeners require regular maintenance, salt replenishment, and can increase your sodium intake. They're a significant upfront investment but offer a long-term solution.

2. Water Filter Pitcher: These pitchers contain a filter that reduces hardness minerals to some extent. They are less effective than a whole-house softener, but they provide a more affordable and convenient option for treating smaller quantities of water, like drinking water. Replacement filters need to be purchased regularly.

3. Reverse Osmosis (RO) System: An RO system is a more advanced filtration system that can effectively reduce water hardness. It uses pressure to push water through a semipermeable membrane, removing minerals, sediments, and other impurities. While extremely effective, RO systems are more expensive to purchase and maintain than pitchers or softeners, and they also waste a significant amount of water during the filtration process.

4. Lime-Scale Inhibitors: These are chemicals that can be added to water to prevent limescale buildup. They are less effective at actually softening the water, but can help to protect appliances. They might be a good temporary option for particular appliances, like kettles.

5. Bottled Water: If the hardness significantly affects your taste or causes health issues, using bottled water for drinking and cooking may be a practical solution. However, this is often expensive and not environmentally friendly.

The best treatment method will depend on factors such as budget, water usage, and desired level of hardness reduction. Consider consulting a water treatment professional to determine the most appropriate solution for your specific needs.

To treat water with a 25 hardness level, consider using a water softener, water filter pitcher, reverse osmosis system, lime-scale inhibitors, or bottled water. The best option depends on your budget and needs.
