Whole-house well water filters for iron stains, hard water, odors and discoloration. Compare systems and pricing, or let the finder match yours in a few questions.
Start with what you notice at home. See the treatment that fits, then confirm the cause with a test.
Treat iron, manganese and hydrogen sulfide before they reach fixtures and laundry, matched to the levels in your water.
See iron treatment
A tannin stage takes the yellow or brown tint out of well water when tannins are the cause.
See tannin treatment
Softening reduces the calcium and magnesium behind hard-water scale, helping reduce buildup on faucets, glassware and water-heating equipment.

Rotten-egg odor can come from hydrogen sulfide. Check whether it occurs throughout the home or only in hot water, then match treatment to the source.
See iron and sulfur treatment
Sediment prefiltration catches sand, silt and rust particles. Check the prefilter included with your configuration; persistent cloudiness may need dedicated turbidity treatment.
See turbidity systems
UV inactivates susceptible microorganisms in clear, pretreated water within its rated flow. Test for bacteria first.
See UV disinfection
Whole-house reverse osmosis reduces dissolved solids. Choose production, storage and pretreatment to suit your water and household.

Five whole house well water filters with live pricing. Send us your water report and a specialist checks the fit before you order.
Iron treatment, SMART filtration and a water softener in one coordinated configuration for wells with metals and hardness.
Factory-tested whole-house RO reduces dissolved solids, with production, pump and storage options to fit your household.
Treats iron, manganese and hydrogen sulfide before they reach your fixtures. 9 to 13 GPM by size, with automatic backwash.
A dedicated stage for confirmed tannins, up to 5 ppm, with combined iron and manganese below 0.2 ppm.
Iron, SMART and carbon filtration for 1 to 2 people, 2 to 4 GPM. No electricity or backwashing.
Americans rely on a private well for drinking water, per USGS.
of about 2,100 private wells sampled by USGS was above at least one health-based drinking-water benchmark.
EPA secondary standard for iron. Above that, water can stain fixtures and laundry and taste metallic.
EPA secondary standard for manganese, another common well metal that stains and affects taste.
EPA maximum contaminant level for nitrate as nitrogen. It does not stain or smell. A lab test is how you know.
EPA recommends testing private wells every year for total coliform, nitrates, total dissolved solids and pH.
Private wells sit outside the Safe Drinking Water Act. The owner is responsible for testing and treatment.
Choose a softener to remove hardness minerals, or a salt-free conditioner to manage scale while keeping those minerals in the water.
Removes calcium and magnesium hardness. The choice when hardness removal and a softer rinse are the goal. Size it to measured hardness, household demand and feed-water chemistry.
Helps manage scale deposits while retaining hardness minerals. No softener salt or brine tank. It does not soften water.
Hard water: choose one
Reduce the hardness minerals behind scale, spots and stiff laundry, with pre and post filtration in the same configuration.
Manage scale without salt regeneration. This conditioner retains hardness minerals; it does not soften the water.
Add-on stage: disinfection
UV disinfection after suitable pretreatment. Match the flow rating and feed-water limits to your system.
The Complete Well Water System above already includes a softener, so it does not need a second one.
Check Compare on any system. The table uses the configuration and add-ons you selected.
Choose two or more systems above and your table appears here.
Back to the systemsIron and sulfur. The iron system carries 1.5 or 2.0 cu ft of media rated for 1,000,000 or 1,500,000 gallons, at 9 to 11 or 10 to 13 GPM. Have your iron, manganese, hydrogen sulfide and pH measured before you choose; very high levels or difficult chemistry can call for an oxidation stage ahead of the filter, which a specialist matches to your results. Browse every iron, manganese and hydrogen sulfide filter.
Tannins. Rated for up to 5 ppm tannins and 40 grains of hardness, with combined iron and manganese below 0.2 ppm. Iron is treated first, in its own stage.
Hardness. The softener holds 45,000 grains (1.5 cu ft) or 60,000 grains (2.0 cu ft) between regenerations and runs at 35 to 60 psi. The salt-free conditioner manages scale while retaining minerals and does not soften water; at 25 grains per gallon or higher it may need pretreatment or additional media, so ask a specialist. The Complete system includes a softener. See all water softeners and whole house water filters.
Reverse osmosis. Feed water up to 15 grains of hardness and 1,000 to 2,000 ppm TDS, pH 3 to 11, at 45 psi or more and 1 to 10 GPM of feed, rated at 77°F; the exact values are in each model's manual. Production in GPD is not faucet flow; the storage tank and delivery pump provide that. Iron, hardness and other membrane-fouling contaminants are treated ahead of the membrane. See whole-house reverse osmosis systems.
UV. Needs clear, filtered water: turbidity below 1 NTU, hardness below 7 grains, iron below 0.3 ppm, manganese below 0.05 ppm, tannins below 0.1 ppm and UV transmittance above 75 percent, at 30 to 60 psi in normal operation and never above 125 psi. UV disinfects; it does not remove chemical contaminants. See UV sterilizers.
Compact cartridge system. Recommended flow is 2 to 4 GPM, for 1 to 2 people. Check simultaneous demand before choosing it for a larger household.
A well water treatment system usually combines more than one stage. Here is what each stage does, in plain terms.
Dissolved iron, manganese and hydrogen sulfide are converted to a form the media can trap, then backwashed away. A sediment prefilter and carbon postfilter finish the job.
See iron treatment
Resin beads exchange calcium and magnesium for sodium or potassium, reducing hardness minerals. Softener salt regenerates the resin as directed for the system.
Compare hard-water options
An RO membrane separates treated water from a concentrate stream that goes to drain. UV is a separate disinfection stage, used after suitable pretreatment within its rated flow.

Start with the finder or the symptoms you notice at home. You can explore and shortlist without a test; measured water chemistry helps confirm the final treatment and size.
Check peak flow, pump pressure, drain, power and service space. Choose the size and finish, then add your configuration to the cart. Review the shipping terms for your order.
Model manuals and connection requirements are linked from each product page. Our filtration specialists are a phone call away if you or your plumber have questions.

Match the treatment to your water: iron and sulfur filtration for confirmed metals and hydrogen sulfide, a softener for hardness, and a tannin stage for confirmed tannins. The Complete system combines iron treatment, SMART filtration and softening. The finder helps you build a shortlist; water chemistry and household flow confirm the final fit.
You can explore systems from the symptoms you notice. A lab report helps confirm treatment and sizing, especially for contaminants you cannot see or smell, such as nitrate, arsenic and bacteria. Choose a test panel that covers your concerns, or send us an existing report.
Start with peak demand: how many fixtures run at once, plus your pump’s available flow and pressure. Compare the selected system’s service-flow and backwash requirements. Compact cartridge filtration is rated for 2 to 4 GPM. Whole-house RO also needs daily production, storage and a delivery pump matched to the household.
Treatment usually goes after the well pressure tank and before the water heater. Iron treatment normally precedes softening, with RO and UV added where appropriate. Your plumber should confirm the model-specific order, drain, power, clearances and service access. The Complete system already includes a softener.
Cartridges, treatment media and RO membranes have different service schedules based on water quality and use. Softeners need salt; UV needs lamp replacement and sleeve care as directed. Each system’s product page and manual explain its replacement parts and maintenance requirements.
Sediment and iron filters are not bacteria treatments. UV is a separate disinfection stage in a well water purification system, used after suitable pretreatment within its rated flow and feed-water limits. Test for bacteria; clear water alone does not establish safety. If harmful contamination is found, follow your local health department’s advice while it is addressed.
On this page, whole-house systems start at $572.32 for the Compact Cartridge System and $1,331 for a tank-based iron and sulfur filter. The Complete Well Water System starts at $3,589. Whole-house reverse osmosis is $5,293 as configured here, with a storage tank and UV. Size, finish and options change the price, and every card shows the live figure. Installation by your plumber is a separate cost.
EPA recommends annual testing for total coliform bacteria, nitrate, total dissolved solids and pH. Your local health department can advise on additional tests after flooding, well repairs or changes in taste, odor or appearance. Compare well-water test panels; the Lite panel does not include bacteria.
