First-Time Buyers: The Homes That Have Never Had a System, and Why More of Them Buy Every Year
Replacements are the easy sale. First-time buyers are the growing one. Softener ownership went from 13 percent of households to 25 percent in four years, whole-house filter systems rose 16 percent in two, and three out of four home buyers now call filtered drinking water in the kitchen essential or desirable. Here is what that does to one metro area, in homes, not percentages.
The homeowner who has never owned a system is not waiting for a dealer. They are waiting for somebody they already let in the door to bring it up.
Short answer
Three Groups of Homes That Buy for the First Time
In the Dallas-Fort Worth metro area, the market calculator counts 40,511 homes a year buying a softener for the first time, 33,152 buying a whole-house filter for the first time, and 15,916 softeners plus 8,754 filters going into new homes as they are built. That is nearly 100,000 first-time tanks a year in one metro, on top of the replacements, and half of them go through plumbers and retail rather than dealers.
33,152
First-time whole-house filters a year: 7.7 percent on top of the 430,550 filters already in place.
24,670
Tanks into new homes a year: 15,916 softeners and 8,754 filters, from 2025 single-family permits.
The Dallas-Fort Worth run was made on 6 October 2026 from live Census data. Source: the water treatment market calculator, with every input labeled measured, surveyed or assumed.
Where the rates come from
Thirteen Percent to Twenty-Five in Four Years
The first-time rates are not guesses. The Water Quality Association (WQA) surveys households every two years. Its consumer surveys found 13 percent of households had a softener in 2017, 19 percent in 2019 and 25 percent in 2021. So the homes without one fell from 87 percent to 75 percent in four years: 12 points out of 87, spread over four years, is 3.45 percent of the remaining homes buying their first softener each year.
Whole-house filters are read the same way. The association's 2025 Consumer Insights Report found whole-house systems rose 16 percent; since it surveys every two years, the calculator reads that as about 7.7 percent a year, the lower of the two possible readings, applied to the filters already in place.
| Measure | Figure | Source |
|---|---|---|
| Households with a softener | 13 percent (2017), 19 percent (2019), 25 percent (2021) | Water Quality Association consumer surveys |
| First-time softener rate | 3.45 percent a year of homes without one | Arithmetic on the three surveys, existing homes only |
| Homes with a whole-house filter | 22 percent | Water Quality Association national survey, January 2021, 1,413 households |
| Whole-house systems, growth | Up 16 percent, read as about 7.7 percent a year | Water Quality Association Consumer Insights Report, 2025 |
| Buyers who want filtered water | 3 out of 4 call filtered drinking water in the kitchen essential or desirable | National Association of Home Builders (NAHB), What Home Buyers Really Want, 2021 |
| Homes without a softener, DFW | 1,174,228 | Arithmetic: 1,957,047 homes less 782,819 with one |
New homes
The Houses That Are Not Built Yet
A permit is the paper a builder gets before building a house, and the U.S. Census Bureau publishes them by county and metro area. In 2025, Dallas-Fort Worth permits put 15,916 softeners and 8,754 whole-house filters into new homes on the calculator's rates: new homes in a 5 to 10 grain market take softeners at 40 percent, and the calculator assumes new homes reach the same 22 percent filter rate as everyone else, bought in the first year.
A new home has no softener in the garage to replace and no history with any plumber. The first company that stands in that utility room with a test strip is the one that gets the first system, and the first service relationship with it.
The new-home ownership rates are the same as the existing-home rates by band, except the under-5-grain band, which Jeff Hubbard's original sheet sets at 25 percent. The 22 percent new-home filter rate is a HALO assumption, labeled as one.
What it adds up to
The Whole Dallas-Fort Worth Market, With First-Timers In
| Line | Softeners a year | Whole-house filters a year |
|---|---|---|
| Replacements | 62,626 | 43,055 |
| Into new homes | 15,916 | 8,754 |
| First-time buyers | 40,511 | 33,152 |
| Changing hands, total | 119,052 | 84,961 |
| Plumber and retail half | 59,526 | 42,481 |
All tanks changing hands: 204,014 a year, of which 102,007 go through plumbers and retail. Totals are quoted as the calculator prints them; adding the rounded rows by hand lands one unit off. One truck closing 39 systems a year is 0.04 percent of the plumber-side total. The number a trained truck has to hit is small enough to be boring, which is the whole point.
Why they buy
The First-Time Buyer Has Already Read About the Water
Gallup found 56 percent of Americans say they worry a great deal about drinking water pollution. Three out of four home buyers tell the National Association of Home Builders that filtered drinking water in the kitchen is essential or desirable. When the City of Dallas sued 3M, DuPont and others on 14 January 2025 over PFAS (per- and polyfluoroalkyl substances) cleanup costs, nobody in a kitchen in Plano needed a contractor to tell them the water was in the news.
The demand is not the problem. The first-time buyer is asking somebody. Right now the answer from most plumbers is some version of "that's not really what I do," and the first system goes to whoever the homeowner finds on their phone that night.

Questions
Questions Owners Ask About First-Time Buyers
How many homes buy a water softener for the first time each year?
About 3.45 percent of the homes that do not have one, on the market calculator's reading of Water Quality Association surveys: ownership rose from 13 percent of households in 2017 to 25 percent in 2021. In Dallas-Fort Worth that is 40,511 first-time softeners a year on the 6 October 2026 run.
Is the whole-house filter market growing?
The Water Quality Association's 2025 Consumer Insights Report found whole-house systems rose 16 percent over its two-year survey cycle. The market calculator reads that as about 7.7 percent a year applied to the filters already in place: 33,152 first-time whole-house filters a year in Dallas-Fort Worth.
How are new homes counted?
From U.S. Census Bureau building permits, published by county and metro area. New homes take softeners at the same rate as existing homes in their hardness band, except the under-5-grain band at 25 percent, and whole-house filters at 22 percent in the first year, a HALO assumption. Dallas-Fort Worth's 2025 permits put 15,916 softeners and 8,754 filters into new homes.
Do home buyers actually want water treatment?
Three out of four home buyers call filtered drinking water in the kitchen essential or desirable, in the National Association of Home Builders' What Home Buyers Really Want survey, 2021. Gallup found 56 percent of Americans worry a great deal about drinking water pollution, 2021.
How big is the whole Dallas-Fort Worth market?
204,014 tanks changing hands a year, softeners and whole-house filters together, with 102,007 going through plumbers and retail rather than dealers, on the calculator's 50/50 split. Those are the calculator's printed totals from live Census data run on 6 October 2026.
