The biggest cost drivers
| Driver | Effect on the quote |
|---|---|
| System type | Under-sink RO, whole-home carbon, softener, or a combined setup |
| House size and bathrooms | Larger homes need higher-flow equipment |
| Water source | City water vs. a private well with iron, sulfur or hardness |
| Installation location | Garage, exterior wall, or a spot that needs new plumbing runs |
| Drain and electrical access | Softeners and some filters need both |
| Permits or code items | Ask whether any apply to your job |
A Florida City advantage: free chlorine
Florida City's 2025 report says its Biscayne Aquifer water is disinfected by chlorination. Free chlorine is generally simpler for carbon to reduce than chloramine, which can affect how much media a whole-home system needs. That is one reason a quote prepared for a county-water home in another part of Miami-Dade is not a fair comparison for yours.
What an itemized quote should list
- The exact equipment models and their certifications.
- Installation labor, materials and any plumbing changes.
- Replacement filter or media schedule and part costs.
- Warranty terms for equipment and labor.
- Who services the system and how to reach them.
More detail in why water filtration quotes differ.
Costs after installation
- Filter cartridges and RO membranes.
- Salt, if you add a softener.
- A small amount of electricity and drain water for some systems.
- Occasional service visits.
Ask for each item in writing before you sign. See the annual cost of owning a whole-home filter.

Why one-size quotes miss
A quote built for a generic South Florida home assumes chloramine, a certain hardness, and a standard garage install. A Florida City home on city water has free chlorine, a hardness level that only a test reveals, and its own plumbing layout. A property on a well can need several stages. If a quote arrives before anyone has tested your water, ask what it was sized for. Jorge's quote shows the test results it is built on, so you can see the reasoning.
Commercial properties
Restaurants, motels, laundries and offices are quoted on daily gallons, peak flow and the equipment being protected. Expect the quote to name each treated line, such as ice machines or water heaters.
