The Best Water Softeners For Large Homes: A Review
Best Water Softeners for Large Homes: High Flow, High Capacity Systems 💧🏠
If you are suffering from hard water, you probably know the importance of investing in a reliable water softener. But choosing the right model—especially for larger homes with 5 or more bathrooms—can be challenging, with limited options.
In this guide, we review the best water softeners for large homes, focusing on crucial factors like flow rate and salt storage capacity. These two features ensure your water softener can handle the water demand of bigger households efficiently.
The Harvey water softener models featured here are highly recommended for large homes due to their impressive flow rates of 80+ L/min and large salt storage capacities . For comparison, popular brands like Kinetico, with models such as the Premier Maxi and Premier Plus, only offer a max flow rate of 56L/min and standard salt storage, which may not suffice for very large households.
