Reverse Osmosis · Houston, TX
Reverse osmosis drinking water in Houston
A reverse osmosis system sits under your kitchen sink and gives you filtered water for drinking and cooking from its own faucet.
About Houston's water
- Houston Public Works says its system serves about 5.5 million people and draws on surface water (Trinity River/Lake Livingston and San Jacinto River/Lake Conroe & Lake Houston) plus groundwater from the Chicot and Evangeline aquifers.
- Houston's 2025 report lists Main System total dissolved solids from 146 to 331 mg/L, averaging 260 mg/L. Reverse osmosis is designed to reduce dissolved solids at the tap where it's installed.
Water varies by home, utility and MUD. Figures come from the public reports linked below.
How we install reverse osmosis
We test your water first, then install an under-sink RO system with its own faucet. Many homeowners pair RO with a softener and whole-home carbon filter in our Softener + Carbon + RO package.
- Water softener installation and whole-home carbon filtration: manufacturer warranty + 1-year labor.
- Reverse osmosis drinking water at the kitchen sink.
- Free mailed water test: the mailed test is free. Booking takes a $20 deposit, credited toward your system when installed; non-refundable if you choose not to install.
- Financing available, subject to approval.
- See all packages.
Seasonal offer: From Nov 18, 2026 to Jan 31, 2027, get $150 off the Softener + Carbon + RO package or the Premium Whole-Home package. The offer does not apply to other packages.

Cost, upkeep, and how RO fits with a softener
A standalone under-sink RO is $795. Added to a softener or filtration package, the RO add-on is $595. Softener + Carbon + RO and Premium Whole-Home are tiers quoted after your free mailed water test. From Nov 18, 2026 to Jan 31, 2027, get $150 off those two whole-home packages.
RO does not treat the whole house. If your water is hard, a softener helps protect the RO membrane and your plumbing. After installation, the RO Filter Plan is $12/month for filter changes and can be canceled anytime.

Common questions
What does a reverse osmosis system do?
It pushes water through a fine membrane and filters to reduce dissolved solids and many other substances, giving you filtered drinking water at one faucet.
Does RO treat the whole house?
No. RO is a point-of-use system, usually at the kitchen sink. For the whole house, pair it with a softener or whole-home carbon filter.
Should I get a softener with RO?
If your water is hard, a softener protects the RO membrane and your plumbing. A water test shows whether you need one.
Do you install RO in Fort Bend?
Yes. We serve homes within 35 miles of Richmond, TX, including Sugar Land, Rosenberg, Fulshear, Missouri City, Katy, Houston, and nearby MUDs.
How much does a reverse osmosis system cost?
A standalone under-sink RO is $795. The RO add-on to a softener or filtration package is $595. Softener + Carbon + RO and Premium Whole-Home are tiers quoted after your free mailed water test. A written proposal after your water test confirms the price for your home. You pay 30% when you approve the proposal and the remaining 70% after installation. From Nov 18, 2026 to Jan 31, 2027, get $150 off the Softener + Carbon + RO package or the Premium Whole-Home package.
What maintenance does an RO system need?
RO filters are replaced on a schedule, which we go over with you at install. After installation, the RO Filter Plan is $12/month and can be canceled anytime. Manufacturer warranty plus 1-year labor is included (5 years of labor on Premium).
How long does installation take?
After you approve the written proposal, a 30% deposit orders your system, which ships to your home. A licensed installer then does a quick on-site reading to confirm your numbers and installs the system. We will give you a scheduled install date once the equipment is on the way. Call (832) 639-4127 if you want to talk through what to expect for your package.
