Hardness of your Water

First, to decide whether to go for a Salt-based or Salt-free water softener, it is important and necessary to check the Hardness of your water.

Water Flow Rate

Based on the amount of water a home needs and the hardness of that water, the water softeners are sized and designed.

Cost of Salt

This is also one of the important factors to consider before buying. Depending on the usage of the system or how often you use the softener, you will need to top up the salt tank. This depends on the regeneration settings of your softener, hardness of your water at your house, and the amount of water that you use.
