Every score shows its number

See what your water needs. Then buy once.

Enter your ZIP code. We show you how hard the water is where you live, and which systems can handle it. Every score we give sits next to the raw number it came from.

Check Price opens the maker's own site. If you buy there, we may earn a cut. It does not change your price or our scores.

SPECSEvery system in our table shows the specs its maker publishes.

USGSPublic water hardness data from the USGS sits behind every ZIP check.

4-PARTEach system gets four scores: flow rate, capacity, warranty, and filter cost each year.

Here is how we score

Every system gets the same four checks

We do not hand out stars. We take four numbers the maker publishes for each system. We score all four the same way, every time.

Then we show you the raw number beside the score. You can see where the score came from. If you read the number a different way, you can, and you should.

Here is what we do not do. We do not take these systems apart. We do not run them in a lab. We read the published specs, we add up the running cost, and we read the warranty terms.

Questions

Frequently asked

How do you score these systems?

We use four numbers the maker publishes: flow rate, grain capacity, warranty term, and filter cost each year. Each one counts the same. We show the raw number next to the score so you can check our work.

Do you test the systems yourself?

No. We do not take them apart and we do not run them in a lab. We read published specs, we add up the running cost, and we read the warranty terms. That is the whole method.

Where does my water result come from?

It comes from public USGS water hardness data, matched to your county. It is an estimate for your county, not a test of your own tap.

How do you make money?

When you use a Check Price link and buy, the maker may pay us a cut. Your price stays the same. The scores come from specs, and the money never touches them.
