Crusty deposits and spotted glassware mean hardness minerals — calcium and magnesium.
Water softenersIndependent home water guides
Cost breakdowns, sizing math and maintenance schedules for reverse osmosis, softeners and whole-house filtration — measured from real installer quotes, not guessed.
Start with the symptom
Every guide on this site starts from a problem you can see, smell or taste — and ends with a system sized to fix it.
Crusty deposits and spotted glassware mean hardness minerals — calcium and magnesium.
Water softenersHydrogen sulfide, common on private wells. Fixable with oxidation or aeration.
Well waterSediment, silt or air. A whole-house filter clears it before it reaches your fixtures.
Whole house filtrationChlorine, TDS or plastic notes. Under-sink reverse osmosis fixes taste at the tap you drink from.
Reverse osmosisDissolved iron and manganese, the classic well-water signature. Needs oxidizing media, not a softener alone.
Iron removalGurgling fixtures and wet patches over the drain field are early septic warnings — cheap to catch now.

Above 0.05 mg/L manganese stains black instead of iron's orange, and the fix depends on concentration and pH, not on whichever filter looks best in a showroom photo.
Read the full breakdown
Five guides, one system
Each topic is covered end to end: what the system costs installed, how to size it for your water, and the maintenance schedule that keeps the warranty valid.
Under-sink and whole-house reverse osmosis: what systems cost installed, how to size them, and the maintenance schedule that keeps a membrane on spec.
Grain-capacity math, salt vs salt-free chemistry, and real installed prices for every softener type.
Point-of-entry filtration: sediment and carbon stages, flow rates, and cartridge replacement intervals that protect water pressure.
Private well treatment: testing, iron and sulfur removal, UV purification — sized from a lab report, not a sales visit.
Pumping frequency, real maintenance costs, and the early failure signs that save a drain field.
How these guides are built
The same three rules apply to every article on this site.
Cost figures come from installer quotes and current retail pricing, dated in the article — never from a manufacturer's brochure.
Grain capacity, flow rate, membrane output: the formula is in the article so you can rerun it with your own water report.
No brand pays for position. When a budget system beats a premium one for your water, the article says so.
