Whole-house water filtration
A softener deals with hardness. Whole-house filters deal with the rest. Here's how to tell what you need.
Whole-house filtration treats all the water coming into the home, not just one faucet. The right setup depends on what's in your water, so a test comes first. On city water, people often add a carbon filter to cut chlorine taste and smell. On a private well, the list of possible issues is longer.
Which filters are common?
- Sediment filters catch sand and grit, which matters most on wells, and protect the softener and fixtures downstream.
- Carbon filters reduce chlorine taste and odor and some organic compounds.
- Iron and manganese filters for water that stains fixtures orange or black. NDSU Extension says a standard softener can handle up to about 10 ppm of iron and manganese, and above that a separate iron removal system may be needed.
- Specialty media for specific problems a lab test turns up.
Why iron and manganese come up here
The Las Cruces water quality report says the city's groundwater carries moderate levels of calcium, manganese and iron. Those last two can stain sinks and laundry and gum up softener resin over time. Wells in the valley and on the East Mesa can be different from city water, so test before picking equipment.
What order does the equipment go in?
When several pieces are used, a sediment filter usually comes first, then any specialty filter, then the softener. The company should explain why its layout fits your test results.
What upkeep is involved?
Every filter needs something: cartridge swaps, backwashing or media replacement. Ask how often and what it involves before you buy, and whether the backwash needs a drain nearby.
The water treatment company prices the job once it knows your water, your plumbing and what equipment fits. We don't quote prices, and any number you hear over the phone before someone has tested the water and seen the install spot is only a rough starting point.

Common questions
Does a softener filter my water?
No. A softener removes hardness minerals. It doesn't remove chlorine taste or sediment, and it isn't built to treat contaminants.
Should I test my well before buying filters?
Yes. The New Mexico Environment Department recommends regular testing, and a lab result lets you match equipment to the actual problem.
