Whole-House Filtration

Whole-House Water Filtration in Houston: Point-of-Entry vs. Point-of-Use

Point-of-entry (POE) systems, whole house filtration, treat every drop entering the home. In a chloramine city, this matters beyond drinking water: chloramine vaporizes in hot showers, dries out skin and hair, and degrades rubber gaskets, toilet flappers, and washing machine hoses over time. POE is also the only way to address hardness and sediment for the whole plumbing system.

Point-of-use (POU) systems, typically under-sink reverse osmosis, polish drinking and cooking water at one tap to a much higher standard than any whole-house system economically can, removing dissolved solids, lead, arsenic, fluoride, and PFAS.

The honest answer for most Houston homes is both: a POE carbon system (plus softening if hardness warrants) for the house, and a POU reverse osmosis unit at the kitchen sink for drinking water. Whole-house RO exists, but for most families it’s overkill.

Therefore, they can address a wide range of concerns, including chlorine, hardness, iron, and harmful bacteria.

What's In Your Water

What's Actually in Houston Tap Water

Before you buy any filtration system, it helps to know what you’re filtering. Based on the City of Houston’s annual water quality reports and independent testing:

Chloramine, Not Free Chlorine

Houston uses monochloramine for residual disinfection because it produces fewer disinfection byproducts than free chlorine. The trade-off: chloramine is far more stubborn than chlorine. Standard activated carbon barely touches it; you need catalytic carbon with adequate contact time, and most bargain filters don’t have it.

Disinfection Byproducts (TTHMs)

Total trihalomethanes in Houston water typically test in the 30 to 60 ppb range, under the EPA’s 80 ppb limit, but well above the Environmental Working Group’s health guideline of 0.15 ppb.

Hardness

City of Houston water runs about 7 to 8 grains per gallon (moderately hard to hard). Suburban MUD well water in Katy, Cypress, and northeast Harris County commonly tests 11 to 17+ gpg, firmly “very hard.” That’s the scale on your fixtures and the film on your glassware.

Total Dissolved Solids (TDS)

Houston-area TDS generally runs 200 to 500 ppm depending on source and season. Not dangerous, but you can taste it, and it’s why reverse osmosis water tastes so different.

Trace Contaminants

Recent reports show arsenic (2 to 4 ppb), combined radium (1.7 to 3.3 pCi/L), and chromium-6 (0.2 to 0.7 ppb) at levels below EPA limits but above stricter health guidelines.

None of this means Houston water is unsafe. It means the last few feet of treatment (the part that decides what you actually drink and bathe in) is up to you.

Where Does Your Water Come From?

City Chloramine Water vs. Suburban MUD Well Water

This is the single most important question we ask before quoting a system, and it’s the one most national buying guides skip entirely: where does your water come from?

	Inside the City of Houston	In MUD Districts
Where	Plus cities like Pasadena and Baytown on blended supply	Much of Katy, Cypress, New Caney, Kingwood, Tomball, and parts of League City and Missouri City
Main problems	Chloramine, disinfection byproducts, taste and odor, moderate hardness	Higher hardness (often 11 to 17 gpg), possible iron staining (orange streaks in toilets), hydrogen sulfide "rotten egg" odor, more sediment. Chlorine levels vary by district
Right foundation	Whole-house catalytic carbon sized for chloramine reduction, optionally paired with a softener or conditioner for scale	Sediment filtration first, then air-injection oxidation where iron or sulfur shows up in testing, then the carbon stage. A softener earns its keep fast at these hardness levels

We test your water at the tap before recommending anything. A Katy well-water package and a Montrose city-water package should not be the same system, and if a company quotes you one without testing, that tells you something.

Houston-Specific Risk

Sediment After Line Breaks, Freezes, and Boil-Water Events

Houston homeowners have learned this one the hard way. Winter Storm Uri in February 2021 burst mains and private lines across the region, and the November 2022 power failure at the East Water Purification Plant put the entire city under a boil-water notice. Every time a main breaks or pressure drops, sediment, rust, and biofilm that normally sit quietly in the distribution pipes get stirred up and pushed toward your home.

A whole-house sediment pre-filter is cheap insurance: it catches that debris before it reaches your tankless water heater, faucet cartridges, and appliance valves. If you’ve ever flushed brown water after a line repair on your street, you’ve seen exactly what a $300–$800 pre-filter would have stopped. It also protects the more expensive carbon and RO stages downstream, extending their life.

What We Install

Types of Water Filtration Systems We Install

Whole-House Carbon Filtration

A tank of activated carbon (catalytic carbon for chloramine) that treats all incoming water. Removes chlorine and chloramine, taste, odor, and many VOCs. Tank-style systems with 1,000,000-gallon media beds last around 10 years with almost no maintenance; cartridge-style systems cost less upfront but need filter changes every 6 to 12 months. For Houston city water, insist on catalytic carbon; standard GAC is not enough for chloramine.

Reverse Osmosis: Under-Sink

A membrane rated to 0.0001 microns strips out up to 99% of dissolved contaminants: lead, arsenic, nitrates, fluoride, PFAS, and TDS. Installed under the kitchen sink with its own faucet. This is the gold standard for drinking water and the cheapest meaningful upgrade you can make ($400 to $1,500 installed).

Reverse Osmosis: Whole-House

Treats the entire home to drinking-water standard. Requires a storage tank, booster pump, pre-treatment, and a drain for reject water; installed cost typically runs $6,000 to $15,000+. We install these where there is a genuine need (high-TDS well water, specific health requirements), but we will tell you honestly if a carbon system plus under-sink RO gets you 95% of the benefit at a third of the price.

Sediment Pre-Filters

Spin-down or cartridge filters (typically 5 to 50 micron) at the point of entry. Essential on MUD well water and strongly recommended on city water given Houston's line-break history. Protects everything downstream.

UV Purification

An ultraviolet lamp that inactivates bacteria, viruses, and cysts without chemicals. Standard on private wells, and a smart add-on for anyone who wants protection during boil-water events: with a UV stage and a power source, the next citywide notice does not disrupt your household. Lamps are replaced annually (about $60 to $120).

Straight talk, no marketing spin

Salt-Free Conditioners vs. True Filtration (and True Softening)

This is where marketing gets murky, so let's be plain. Salt-free conditioners (template-assisted crystallization, magnetic/electronic devices) do not remove hardness minerals; they change how minerals crystallize so less scale sticks. TAC systems have decent supporting evidence for scale reduction; magnetic conditioners have mixed independent results, and some carry no third-party certification at all. Salt-based softeners actually remove calcium and magnesium via ion exchange. Your water tests soft afterward. And neither one is filtration: conditioners and softeners don't remove chlorine, chloramine, or contaminants. If a salesperson pitches one box that "does it all," ask which NSF/ANSI standards it's certified to (42 for aesthetics, 53 for health contaminants, 44 for softening). The answer is usually silence. Hardness is a different problem with a different fix, which is why we handle water softener installation in Houston as its own service.

Brands We Work With

Top Water Filtration Brands We Install & Service

We are not a single-brand dealership. We install and service the systems below and will match the brand to your water test and budget.

Aquasana

The Rhino EQ-1000 (about $1,700 to $1,800 equipment) carries a 1,000,000-gallon/10-year rating and pairs chlorine reduction with salt-free scale control; the EQ-600 is the 600,000-gallon/6-year version. Well-water Rhino models add UV. Weak points: full warranty requires professional installation, and the 20-inch pre and post filters need regular changes; flow can lag in larger homes.

Pentair

Huge catalog from cartridge housings to commercial media tanks. The PC600 whole-house carbon (600,000 gallons) and the PSE1800 filter/softener combo (100,000-gallon rating, 12-month warranty) are common residential picks. Strength: parts availability is the best in the industry. Weak point: short standard warranties compared with SpringWell or SoftPro.

Culligan

Dealer-installed systems with local service. Whole-house filtration typically runs $2,000 to $10,000 installed; RO systems $1,000 to $3,000 installed, with rental options available. Strength: nationwide service network. Weak points: opaque quote-only pricing and proprietary filters that lock you into the dealer.

SpringWell

The CF1 whole-house catalytic carbon plus KDF system (about $1,100 to $1,500 equipment) is one of the best values in the category: 1,000,000-gallon media life, roughly $40 per year upkeep, limited lifetime warranty, 6-month money-back guarantee. Weak point: sold direct-to-consumer, so you need a plumber (us) for proper installation; the system as a whole is not NSF-certified even though its media is well proven against chloramine and THMs.

Kinetico

Premium non-electric, dual-tank systems sold through dealers, typically $3,000 to $9,000 installed. The K5 Drinking Water Station RO is certified to reduce PFOA/PFOS. Strengths: unpowered operation and long component warranties (10 years on many parts). Weak points: highest prices in the industry and dealer-only proprietary cartridges.

Halo 5

A five-stage tank system (GAC, catalytic carbon, Filter-AG sediment media, garnet bed, plus the HALO ION inline conditioner), typically $3,000 to $5,500 installed in Houston, backed by a 10-year warranty and automatic backwashing instead of cartridge changes. Its catalytic carbon handles chloramine well, which is why it is popular here. Be clear-eyed about one thing: the ION stage is a conditioner, not a softener; it reduces scale adhesion but does not remove hardness, and that stage carries no WQA certification. On very hard MUD water we often pair a Halo with a true softener.

APEC

The ROES-50 under-sink RO (about $200 to $250 equipment) is a 5-stage, 50-gallon-per-day workhorse, WQA/NSF certified to standards 58 and 372, assembled in the USA. Weak point: modest 50 GPD output and a basic warranty (extendable with registration).

iSpring

The RCC7 under-sink RO (about $200, 75 GPD, NSF/ANSI 58 certified) and the WGB32B 3-stage whole-house cartridge system (about $400 to $450) are the strongest budget options we install. Weak points: 1-year warranties and cartridge replacement costs that add up (roughly $200+ per year on the WGB32B).

Houston Installed Pricing

What You Can Expect to Pay

National averages don't reflect Houston plumbing realities (slab foundations, garage or exterior installs, MUD well water pre-treatment). Here's the broad shape of what our customers actually pay, installed.

A whole-house sediment pre-filter, the cheapest insurance in the category, typically runs $250 to $800. A chloramine-rated catalytic carbon tank, the workhorse system for City of Houston water, generally lands in the $1,800 to $3,500 range. An under-sink reverse osmosis unit, installed with its own faucet, runs $400 to $1,500. Well-water packages, softener combinations, UV stages, and whole-house RO climb from there, and the exact number depends on your water test, your service line, and where the system has to go.

How It Works

Our Installation Process

Free water test and quote

We test hardness, chlorine and chloramine, TDS, iron, and pH at your tap, city or MUD, and walk the proposed install location. No trip charge.

System matching

We size the system to your service line, bathroom count, and peak flow so you never notice a pressure drop, and we quote exact installed pricing in writing.

Professional installation

A licensed plumber (not a subcontracted handyman) cuts in the system at the point of entry with a full bypass loop, so you can route around the system for maintenance without losing water. Most installs finish in 3 to 6 hours; same-day service is often available.

Commissioning

We flush the media, sanitize RO storage tanks, set backwash cycles, and re-test the water so you see the before and after numbers.

Walkthrough and registration

We show you the bypass, filter change points, and maintenance schedule, and register your manufacturer warranty.

Ongoing service

Reminder-based filter changes, UV lamp swaps, and annual checkups if you want them, or we'll show you how to DIY the cartridges.

Frequently Asked Questions

What is the best water filtration system for a house?

For most Houston homes on city water, the best setup is a whole-house catalytic carbon system (for chloramine, taste, and odor) plus an under-sink reverse osmosis unit for drinking water. On suburban MUD well water, add a sediment pre-filter and, if hardness tests above 10 gpg, a true softener. There’s no single “best” brand; the best system is the one matched to your water test.

How much does a whole house water filtration system cost?

In Houston, most whole-house installations run $1,800 to $5,500 installed, depending on whether you choose a cartridge system or a chloramine-rated catalytic carbon tank, and whether softening is included. Budget cartridge systems start around $800 installed; whole-house reverse osmosis runs $6,000 to $15,000+. We quote exact pricing free, with no trip charge.

Does water filtration remove lead?

It depends on the technology. Reverse osmosis and carbon filters certified to NSF/ANSI 53 for lead reduction remove it effectively; a basic sediment filter or fridge filter may not. Houston’s supply generally tests low for lead, but homes built before 1988 can have lead solder or galvanized lines adding lead at the house level. If that’s your situation, we can test for it and discuss whether a repipe is the permanent fix.

How does water filtration work?

Most systems work by adsorption, physical straining, or membrane separation. Carbon media adsorbs chlorine, chloramine, and organic chemicals onto its surface; sediment filters physically strain particles down to a micron rating; reverse osmosis forces water through a membrane so fine that dissolved metals and salts can’t pass. Multi-stage systems chain these together, each stage protecting the next.

What is reverse osmosis water filtration?

Reverse osmosis pushes water through a semi-permeable membrane with pores around 0.0001 microns, rejecting up to 99% of dissolved solids: lead, arsenic, fluoride, nitrates, PFAS, and salts. The rejected concentrate goes to the drain, and purified water is stored in a small tank at your kitchen sink. It’s the most complete drinking-water treatment available for homes.

Does a whole house filter remove chloramine?

Only if it’s built for it. Chloramine is much harder to remove than free chlorine. Standard GAC cartridges make a small dent, while catalytic carbon with sufficient contact time removes it reliably. Since Houston uses chloramine, we only install chloramine-rated systems on city water.

Do I need a water softener or a water filter in Houston?

They solve different problems, and many homes need both. A filter removes chloramine, taste, odor, and contaminants; a softener removes hardness minerals that cause scale. City of Houston water at 7 to 8 gpg makes a softener optional; MUD well water at 11 to 17 gpg makes it a strong recommendation. A salt-free “conditioner” is not a substitute for either.

How long does a whole house water filtration system last?

Tank-style catalytic carbon systems last 8 to 12 years (about 1,000,000 gallons) before a media rebed. Cartridge systems last indefinitely, but cartridges need changing every 6 to 12 months. RO membranes last 2 to 5 years, and UV lamps get replaced annually. We track all of it if you’re on our service plan.

Will a filtration system lower my water pressure?

Not if it’s sized correctly. Problems happen when a 10 GPM system gets installed on a 3-bath home that peaks at 14 GPM. We size against your service line and fixture count, and every install includes a full bypass so the system can never leave you without water.

Is Houston tap water safe to drink without a filter?

It meets EPA standards, so yes in regulatory terms. But it contains chloramine, disinfection byproducts above strict health guidelines, and 200 to 500 ppm of dissolved solids, and every main break or freeze event can push sediment into your lines. Filtration is about closing the gap between “legally acceptable” and what you actually want your family drinking.
