Whole-House Water Filters for Round Rock Chloramine
If your complaint is taste or smell rather than spots, filtration is the fix. On Round Rock water, the key is choosing media that can handle chloramine.
A whole-house water filter costs about $1,000–$4,000, averaging roughly $2,000, per Networx's 2026 guide. Round Rock disinfects with chloramine, which averaged 2.15 ppm in 2025. Catalytic carbon removes chloramine far better than standard carbon. A filter doesn't soften water; pair it with a softener if spots bother you too.
Why chloramine changes the filter choice
Chloramine is chlorine bonded with ammonia. It lasts longer in water mains, which is why utilities use it, and it's harder to strip out at home. Standard activated carbon removes free chlorine quickly but needs far more contact time for chloramine. Catalytic carbon is made for the job. Round Rock's 2025 readings ran from 1.80 to 2.41 ppm, averaging 2.15, well under the 4 ppm limit (City of Round Rock 2025 report). The goal of filtering is taste and smell, not fixing a violation.
Byproducts, PFAS and what the report shows
- Disinfection byproducts: total trihalomethanes had a highest locational running average of 65 ppb against an 80 ppb limit, and haloacetic acids 21 ppb against 60. Carbon reduces both.
- PFAS: PFOA, PFOS, PFHxS, GenX, PFBS and PFNA were all below the minimum reporting level in 2025 monitoring.
- Hardness: unaffected by carbon. Minerals pass right through.
All figures are from the City of Round Rock's 2025 report.
When a filter is the better buy
If the pool-like smell in the shower bothers you more than spots on the glass, start with filtration. If ice cubes and coffee taste off, a filter helps, and under-sink RO helps more. If spotting is your only complaint, a filter won't change it, and a softener is the tool. Plenty of Round Rock households need only one of the two, which keeps the cost toward the low end of the published range.
Sizing and setup
A backwashing catalytic carbon tank costs more but runs for years between media changes; cartridge housings cost less but need frequent swaps under chloramine. Size the tank to peak household flow so showers don't lose pressure. With a softener, the filter usually goes first so the resin stays protected.

Questions homeowners ask
Can I just use a pitcher filter?
For drinking water, maybe, if it's rated for chloramine. A whole-house filter treats showers, laundry and every faucet, which is the point if the smell bothers you in the bathroom too.
Is Round Rock water safe to drink without a filter?
The city reports that its water meets or exceeds all state and federal standards, and TCEQ rates the system superior. Filtration here is about taste, smell and preference.
