Does RO handle chloramine?

The carbon pre-filter reduces chloramine before the membrane. Sizing and change intervals matter.

Will RO remove fluoride?

Many RO systems are certified under NSF/ANSI 58 for fluoride. Check the exact model.

Can I connect my ice maker?

Usually yes, with an extra line.

Some water goes to the drain during production; the ratio depends on the system and pressure.

Can condo owners install one?

Usually, with association approval. It sits under the sink.

What happens to the minerals RO removes?

They are rinsed to the drain with a small stream of water during production.

Under-Sink Reverse Osmosis in Miami Shores

Stage by stage

Stage	Job
Sediment	Catches particles
Carbon (catalytic where needed)	Reduces chloramine, which WASD reports at a 2.5 ppm average, to protect the membrane
RO membrane	Lowers dissolved solids such as salts and minerals
Post-filter and alkaline	Polishes taste and remineralizes

Because chloramine is slower to break down than free chlorine, the pre-filter in a Miami Shores system does real work. A good design gives it enough carbon and enough contact time, and the schedule replaces it before chloramine can reach and wear the membrane.

Why Miami Shores households choose RO

A dedicated tap that ends the bottled-water run.
Better-tasting coffee, tea and ice.
Peace of mind in older homes: WASD's lead service line inventory and your home's own plumbing are separate questions, and for lead claims you should only trust a model certified under NSF/ANSI 58 for lead reduction.
Works in rentals and condos with landlord or association approval.

Installation in older kitchens

Older Miami Shores kitchens sometimes have shallow cabinets, cast-iron drains or stone countertops. Jorge checks:

Cabinet depth and whether a compact unit fits better than a tank.
Where to mount the faucet, and whether the countertop needs drilling.
The drain connection point.
An optional line to the fridge or ice maker.

See the compact alkaline RO.

Jorge also checks water pressure. RO membranes need adequate pressure to produce water efficiently; low pressure means slower production and more water to the drain, and in some homes a small booster pump is the fix.

Certification is model-specific

NSF/ANSI 58 covers RO systems. Every reduction claim, whether lead, arsenic, fluoride, PFAS or dissolved solids, applies to the exact listed model with filters changed on schedule. Ask to see the listing for anything you consider, including ours. Read alkaline vs. standard RO.

Keeping it working

Pre-filters protect the membrane from chloramine and particles, so their schedule matters most. Jorge gives you the intervals and part list up front. Cost factors are on RO cost in Miami Shores.

A dissolved-solids reading at each service visit is a simple way to confirm the membrane still performs. If the number from the RO faucet creeps up toward the tap reading, it is time for a change.
