Water Treatment Guides

Step-by-step decision frameworks to help you choose the right water treatment system. Start with your water data, not a sales pitch.

Most people start shopping for water treatment equipment without understanding what they actually need. That is how you end up spending $1,500 on a softener when a $200 filter would have solved your problem, or vice versa. These guides walk you through the decision from your water data to the right category of system, before you ever look at a specific product.

Frequently Asked Questions

Do I need a water softener or a water filter?
A softener removes hardness minerals (calcium, magnesium) that cause scale. A filter removes contaminants (chlorine, PFAS, lead). They solve different problems. Many homes need both. Read the full decision guide
How do I know what size water softener I need?
Use the formula: (people × 75 gallons × hardness in GPG) × 7. A family of 4 with 15 GPG water needs about 32,000 grains. Sizing calculator
Is reverse osmosis worth it?
Only if you have specific contaminant concerns like PFAS above 4 ppt, high TDS, arsenic, or fluoride. For hard water alone, a softener is better and less wasteful. RO guide
How much does a water softener cost to install?
Total installed cost: $600-2,500. Equipment $400-2,000 plus $200-500 for professional installation. Ongoing salt costs $50-100/year. Full cost breakdown
