Actually, no. A softener's capacity is a measure of how much soft water can be produced before a softener needs to regenerate. This is dependent on how much resin the softener can hold and the hardness level of your water (and potentially the amount of water iron content you have). If you have a big family with lots of water-based appliances, it makes sense that you're going to need a softener with a bigger capacity to provide you with a greater amount of soft water before it needs to regenerate.
