Softener, filter, iron system, well pump. Most sites push a brand before anyone asks what is actually in your water.
Your water has a problem. Here is what it actually costs to fix.
Start with the symptom. Get the real installed price, plumber included. Then a straight BUY or SKIP on every system, with the spec sheet open.

The whole path
Follow your water, from the source to your tap
Six stages sit between the ground and your glass. Knowing which one owns your problem is most of the decision.
01
The source
City main or your own well. Everything downstream is chosen by what is in the water here — hardness, iron, sulfur, sediment. Test first; buy second.
Well water guide →02
Pump and pressure tank
On a well, the pump and pressure tank set the pressure everything else depends on. Short cycling here is usually the switch or a waterlogged tank, not the pump.
Well and pumps →03
The softener
Ion exchange strips hardness minerals off resin and flushes them to drain. Size it to your actual grains per gallon or it regenerates twice a week.
Softener buying guide →04
Whole-house filtration
Carbon for chlorine, taste and odor. Air injection for iron and sulfur. What matters is media volume and flow rate at rated service, not the brand on the tank.
Filter buying guide →05
UV, if you are on a well
UV handles biologicals that filtration does not. Dose depends on flow rate and how clear the water already is — cloudy water shades the organisms from the lamp.
UV purifier guide →06
Your tap
This is the only place the result is measurable. Work back from what is wrong here — stains, smell, scale, pressure — and the equipment picks itself.
Start with the symptom →Start with your water, not a product
Well water, fixed
Iron stains, rotten-egg smell, sediment — match the contaminant to the right media, not the loudest brand.

Head-to-head verdicts
SpringWell vs Aquasana. Kind vs iSpring. Same specs, same math, one winner — and we link to both either way.
No loser-bashing. Just spec sheets.

What we'd buy in each lane
Why trust a verdict
Every claim traces to a number
Flow rate at rated service. Media volume in cubic feet. NSF/ANSI certification scope — not the marketing version. The installed price including the plumber, not the teaser price. When a spec is missing from a manufacturer's sheet, we say so instead of guessing.
