Comparing the options
| Option | Strengths | Limits |
|---|---|---|
| Under-sink alkaline RO | Dissolved solids, chloramine taste, steady supply | One faucet; some drain water |
| Pitcher | Low entry cost, portable | Small batches; many struggle with chloramine |
| Fridge filter | Convenient | Short contact time; check certifications |
| Whole-home | Chloramine at every tap | Doesn't reduce dissolved solids like RO |
Pitchers and fridge filters are cheapest to start but need frequent cartridges; RO costs more to install but delivers more water per day at a dedicated faucet; whole-home costs the most up front and treats everything. The right choice depends on how much water your household drinks and cooks with, and on what bothers you about the tap.
What the 2025 report suggests
WASD's report shows chloramine as the disinfectant, sodium up to 33 ppm, fluoride no longer added since June 2025, and a PFAS table with compliance monitoring underway. For taste and dissolved solids, RO is the strongest at-the-tap option. For any specific contaminant, the exact model must be certified for it.
If your family prefers to keep the natural fluoride, a carbon-based system generally leaves it in; RO generally reduces it.
By type of home
- Single-family house: kitchen RO, often with whole-home filtration.
- Townhome or condo: kitchen RO, following association rules.
- Office in a Miami Lakes business park: break-room RO sized to the number of users.
- Private well: treat the well first, then add RO.
Households that cook a lot, fill pets' bowls or make baby formula get the most from a dedicated RO faucet; for formula, follow your pediatrician's guidance.
Mistakes to avoid
- Assuming any pitcher handles chloramine.
- Expecting a fridge filter to cover the kitchen sink too.
- Expecting whole-home filtration to match RO for drinking water.
- Letting filters run past their schedule.
A short conversation after a test usually avoids all four, and costs nothing.
Questions to ask
- Which certifications does the model hold, for which contaminants?
- How often are filters changed?
- How much water goes to the drain?
