Why the island leans toward filtration
NMB Water's 2025 report describes three treatment processes at Norwood, lime softening, nanofiltration and reverse osmosis, followed by blending and disinfection. Hardness is reduced before the water leaves the plant. The disinfectant, chloramine, stays in the water on purpose all the way to your building. So the most common complaint at a Sunny Isles faucet is taste and smell, not scale.
Five quick questions
- Does the water smell like a pool? Filter.
- Is there heavy white crust on aerators even with regular cleaning? Test hardness.
- Do you own a house or a whole building's mechanical room? Then a softener is at least possible.
- Do you run a kitchen, laundry or spa? Softening may protect equipment.
- Is there rust or a rotten-egg smell? Neither device is the first answer; see iron stains and sulfur smell.
When both make sense
A hotel or a large house with measured hardness and a chloramine complaint may use both. The filter usually goes first, which also protects the softener resin from the disinfectant. Salt-free conditioners are a separate category: they neither remove chloramine nor stop spots the way ion exchange does. See salt-free vs. ion-exchange.
Upkeep compared
A chloramine filter's ongoing cost is media or cartridge replacement on a schedule set by your water use. A softener's is salt, the water used to regenerate, and periodic service, plus a place to store salt, which is not trivial in a tower or a compact house. Buying equipment you do not need doubles the upkeep for no benefit. That is why the order matters: test, solve the real problem, and only add the second system if the numbers call for it. Cost drivers for each are on the filtration cost and softener cost pages.
Condo owners' practical path
Start with under-sink RO for drinking and cooking water. Add a chloramine-rated shower filter if the bathroom smell bothers you. For glass spots, use a squeegee and good ventilation. If many owners want more, central treatment is a question for the board and its engineer.
