🏠 Household term
Reverse osmosis
A water filtration method that pushes water through a very fine membrane. It removes much more than a basic filter but produces waste water and needs installation.
Why it matters
RO removes much more than a basic filter, but it costs more, takes space and produces waste water.
🇸🇬 In Singapore
Because Singapore’s tap water already meets drinking water standards, reverse osmosis is a choice rather than a need for most homes. Weigh the space, installation and waste water against the benefits.
Tips before you buy
- Check cabinet space and installation needs.
- Ask about maintenance and membrane replacement.
- Get landlord approval if you rent.
