About

Who we are

Clear, honest answers about your water

SoftWaterHQ is an independent resource that helps American homeowners understand their water and choose the right treatment for it. Hard water, chlorine taste, rusty stains, well water worries: we explain what is going on and what actually fixes it, in plain English.

Shopping for a water softener or filter is confusing. Product pages are full of marketing claims, sizing charts assume you already know your grains per gallon, and many “reviews” are written to sell, not to inform. We built SoftWaterHQ to be the site we wished existed: clear explanations first.

Our process

How we research every guide

1

Start with real questions

We use keyword and search data to find what US homeowners actually ask about their water.

2

Go to primary sources

Facts, limits and health information come from government agencies and standards bodies, not product pages.

3

Check costs against data

Price ranges come from published cost guides and are labeled with their source and date.

4

Explain the trade-offs

We cover the downsides of every option, including the ones that are more profitable for the industry.

5

Cite our sources

Each guide lists the sources it relies on at the bottom of the page, so you can check them yourself.

6

Review before publishing

Numbers, standards and dates are checked against the sources before an article goes live.

Trusted sources

Where our facts come from

We also use independent research, such as university studies on water softener alternatives, and published cost data.

Original data

We build our own data tools

Where good data is hard to find, we compile it ourselves. Our US hard water map and ZIP code lookup bring together utility-reported hardness for all 50 states, 16,000+ cities and about 40,000 ZIP codes, with the method and data source explained.
