Whole-house water filtration in Collin County
A softener fixes scale. It does nothing about the chloramine taste that shows up in your coffee and your shower. Whole-house carbon filtration handles that at the main line — every tap, every shower, not just the one with a pitcher next to it.
Why our water tastes the way it does
The North Texas Municipal Water District disinfects with chloramine — chlorine combined with ammonia. It's used instead of free chlorine because it stays stable much longer as water travels the miles of pipe between the Wylie treatment plant and your house. It's safe, it's required, and it's doing an important job.
It's also the reason your water tastes like a swimming pool. Chloramine is more persistent than chlorine, which means it doesn't dissipate if you leave a pitcher on the counter overnight the way chlorine does. And in a hot shower it comes out of solution as vapor, which is why the smell is often strongest in a closed bathroom.
Alongside it, water picks up sediment on the way to you — fine rust and scale from distribution mains, plus whatever comes loose after a main break or hydrant flush in your neighborhood.
Catalytic carbon, not just carbon
This is the detail that separates a system that works here from one that doesn't.
Standard granular activated carbon — the media in most filters and every fridge filter — is designed for free chlorine. It handles chloramine poorly, because chloramine breaks down far more slowly on ordinary carbon. Water moves through the tank faster than the reaction can finish, and a meaningful amount comes out the other side untouched.
Catalytic carbon is carbon whose surface has been modified to dramatically speed up that reaction. It's the media that actually works on NTMWD water, and it costs more — which is exactly why some quotes don't specify it.
What to ask any company quoting you. "Is the media catalytic carbon, and how many cubic feet?" If they can't answer both, or the answer is just "carbon," the system may not do what you're paying for on chloraminated water.
Sizing: it's about flow rate, not household size
A softener is sized by how much hardness it has to remove per week. A filter is sized differently — by how fast water moves through the media. Water needs enough contact time with the carbon for the reaction to finish, so the tank has to be big enough to handle your home's peak demand without rushing.
That means the number that matters is how many fixtures might run at once. Two showers, a dishwasher, and an irrigation zone is a very different peak than a couple in a two-bath house.
| Home | Peak demand | Typical tank |
|---|---|---|
| Up to 2.5 baths | 7–9 gpm | 1.5 cu ft |
| 3–4 baths | 9–12 gpm | 2 cu ft |
| 4+ baths, large home | 12–16 gpm | 2.5–3 cu ft |
Undersize it and you get two problems at once: chloramine gets through, and you lose water pressure across the whole house. Pressure loss after a filter install almost always means the tank is too small for the home.
Tank systems vs. cartridge systems
Backwashing tank systems
A tank of loose media with a valve on top that periodically backwashes itself — reversing flow to lift the bed, flush out trapped sediment, and prevent channeling. More expensive up front, but the media lasts five to seven years and there's nothing to change in between. This is what we install in most homes.
Cartridge systems
One or more housings with replaceable cartridges. Cheaper to install, no drain line required, and a reasonable choice where there's no drain access. The catch is cartridges every six to twelve months — which over a decade usually costs more than the tank system you didn't buy.
Combination softener + filter
Carbon media and softening resin in a single tank, or two tanks plumbed in series. Most Collin County homes need both jobs done, and doing them together saves space in the garage and typically several hundred dollars over buying the systems separately. If you're installing anything, this is usually the conversation worth having.
What it costs
Most whole-house filtration installs in Collin County run $1,800 to $4,500. What moves you within that range:
- Tank size — driven by your peak flow, as above.
- Media — catalytic carbon costs more than standard carbon, and it's the one thing not worth cutting.
- Sediment pre-filter — a spin-down or cartridge pre-filter ahead of the carbon protects the media and extends its life.
- Drain access — backwashing systems need a drain. If there isn't one near the install point, running it adds labor.
- Combination systems cost more than a filter alone but less than a filter plus a separate softener.

Common questions
Why does my water taste like a swimming pool?
NTMWD disinfects with chloramine, which stays stable longer in the pipes than free chlorine. It's safe, but many people taste and smell it — especially in hot showers, where it comes out of solution as vapor.
Will a regular carbon filter remove chloramine?
Not well. Chloramine breaks down slowly on standard carbon, so a lot of it passes through. It needs catalytic carbon, a modified media that speeds the reaction up. If a quote doesn't specify catalytic carbon, ask.
Do I need a softener and a filter, or just one?
They fix different things — hardness versus taste and odor. Most homes here have both problems, which is why combination systems are common. If you only have one complaint, we'll tell you which system solves it and leave the other alone.
How often does the media need replacing?
Five to seven years for catalytic carbon in a correctly sized backwashing tank. Cartridge systems need cartridges every six to twelve months.
Will it hurt my water pressure?
Not if it's sized right. Pressure loss after a filter install almost always means the tank is too small for the home's peak demand.
