How to Choose the
Right Size Water Softener
Determining the right size water softener for your home can feel overwhelming. This guide is designed to simplify the process and help you find the ideal system that meets your needs and fits your budget.
Let us guide you with a quick quiz to find the
perfect softener
and size for your home.

Find Your
Softener Size (2 min)
Water Softener Sizing Chart (the easy way)
Step 1: Find your water hardness in “grains per gallon” or “GPG”
- If you don’t know your water hardness, here's a water hardness map for an approximation. Optionally you can get a laboratory water analysis for exact figures. This is recommended for anyone utilizing well water.
Step 2: Cross reference the table below:
- Take the average number of people in your home, and reference the corresponding column.
- When your water hardness and number of people intersect, you can find the recommended softener size.
NOTE: Other considerations may be necessary for homes on well water. Iron and competing contaminants may change the recommended system size.
Number of people in your home | ||||
---|---|---|---|---|
Hardness in Grains Per Gallon | 1 to 2 People | 3 to 4 People | 5 to 6 People | 7 to 8 People |
5 - 10 GPG | 35,000 grains (10 GPM) | 35,000 grains (10 GPM) | 35,000 grains (10 GPM) | 53,000 grains (15 GPM) |
11 - 20 GPG | 35,000 grains (10 GPM) | 35,000 grains (10 GPM) | 53,000 grains (15 GPM) | 70,000 grains (20 GPM) |
21 - 30 GPG | 35,000 grains (10 GPM) | 53,000 grains (15 GPM) | 53,000 grains (15 GPM) | 70,000 grains (20 GPM) |
31 - 40 GPG | 53,000 grains (15 GPM) | 53,000 grains (15 GPM) | 70,000 grains (20 GPM) | 70,000 grains (20 GPM) |
41 - 50 GPG | 70,000 grains (20 GPM) | 70,000 grains (20 GPM) | 70,000 grains (20 GPM) | 70,000 grains (20 GPM) |
51 - 75 GPG | If your water hardness exceeds 50 grains per gallon, we urge you to consider a Whole House Reverse Osmosis System for less maintenance (no lugging salt), the best water quality (filters the most contaminants), and peace of mind. | |||
76 - 100 GPG |
