Most Longwood homeowners searching for a whole house reverse osmosis system are really searching for one thing: bottled-water quality at every tap, not just the one under the kitchen sink. Here’s how whole-home RO actually works, where it struggles with Seminole County’s mineral-rich (hard) water, and why Reactive Osmosis (RO2) is the way we install it.
What is a whole house reverse osmosis system in Longwood?
A whole house reverse osmosis system treats water where it enters the home, at the main line, so every fixture in the house is fed purified water—kitchen, bathrooms, laundry, ice maker and outdoor spigots alike. That’s the difference between whole home reverse osmosis and a point-of-use RO unit, which purifies a single faucet and leaves the rest of your Longwood home on untreated water.
Why traditional whole house RO is hard to live with in Longwood
A true reverse osmosis membrane produces water slowly and under pressure, so a whole house RO system has to bank it: a large pressurized storage tank, a booster pump to refill it, and a brine line that sends a significant share of your incoming water to the drain. Run two showers and the dishwasher at once in a busy Longwood home and you can outrun the tank. The equipment footprint, the wasted water and the pump are the three reasons most homeowners abandon the idea.
How Reactive Osmosis (RO2) is different
Reactive Osmosis reaches reverse osmosis quality water by filtration rather than by pressurized rejection. Multi-stage media - a 5-micron sediment pre-filter, KDF-55 copper-zinc redox alloy and a 0.5-micron carbon block - handle sediment, chlorine, heavy metals, VOCs, taste and odor. For Longwood and Seminole County's mineral-rich groundwater, it also helps address the scale that hard water can leave behind. A hollow-fiber membrane with pores at or under 0.01 microns then blocks bacteria, cysts, colloids, microplastics and many viruses outright. No storage tank, no booster pump, no brine line, and 15 gallons per minute on demand.
Does whole house RO remove fluoride, chlorine and heavy metals in Longwood water?
Chlorine, chloramine byproducts, hydrogen sulfide, VOCs, pesticides and dissolved heavy metals such as lead, mercury, nickel and chromium are handled by the KDF-55 and carbon stages. Bacteria, cysts, microplastics, turbidity and fine suspended solids are blocked by the membrane. Dissolved salts and TDS are the honest exception—lowering those takes a true RO membrane, trading off the tank, pump, and brine.
How much does a whole house reverse osmosis system cost in Longwood?
Whole home reverse osmosis systems commonly run several thousand dollars once the tank, pump, plumbing and labor are counted. Our complete whole-house Reactive Osmosis (RO2) system is $2,995 installed - regularly $5,000, so you save $2,005. That price includes the cartridge housings, manifold, membrane vessel, professional installation, a water test and a system check before we leave for your Longwood home.
City water or well water—and where we install in Longwood
On municipal supplies, the KDF-55 and carbon stages take on chlorine, disinfection byproducts, taste and odor at the main line. On rural wells and sediment-prone plumbing, the 5-micron pre-filter and membrane handle silt, rust, turbidity and biological contamination together. We install whole house RO-quality systems across Longwood and Seminole County—often in a single visit.
