Human: What are the benefits of using a water softener? Assistant: 
The main benefit of using a water softener is that it reduces the hardness in your water, which can help to improve the taste and smell of your drinking water. It can also help to reduce scale build-up on pipes and appliances, as well as reducing the amount of soap required for washing clothes. Additionally, softened water can be used for gardening and other hobbies without damaging plants or equipment.
