A finer approach to water filtration
Reverse Osmosis, often shortened to RO, uses pressure to move water through a semi-permeable membrane. Water passes through while the membrane reduces many dissolved substances and other contaminants.
The exact reduction depends on the system, filter condition and source water. Check the manufacturer’s performance data for the model you choose.
How it differs from common filters
Basic filtration can help with sediment, chlorine, taste and odour. Reverse Osmosis adds a much finer membrane stage designed to reduce a broader range of dissolved substances.
Philips combines RO with pre-filters and post-filters, giving each stage a clear job while helping protect the membrane and refine the finished water.
What happens inside a multi-stage system?
- Pre-filtration reduces sediment, chlorine and organic material before the water reaches the RO membrane.
- The RO membrane separates water from many fine and dissolved substances.
- Post-filtration helps refine taste and odour before the water is dispensed.
Some systems include an additional mineral stage. Features vary between models, so compare the product specifications and maintenance schedule.
QDoes Reverse Osmosis remove every contaminant?
ANo water treatment system removes every contaminant. Reduction claims vary by model. Review the product performance information and choose a system tested for the substances you want to reduce.
QDoes Reverse Osmosis change the taste of water?
AMany systems include a post-filter to refine taste and odour. Taste is personal and will also depend on the source water and the system.
QDoes Reverse Osmosis remove minerals?
ARO can reduce dissolved minerals along with other substances. Some systems add minerals after the RO stage, so check how each model is configured.
QDoes a Reverse Osmosis system use additional water?
ARO creates a stream of treated water and a separate reject stream that carries concentrated substances away. Water efficiency varies between systems and should be part of your comparison.
QHow should a system be maintained?
AReplace filters and membranes according to the manufacturer’s schedule. Regular maintenance helps the system perform as designed.
Why Philips Water partners with Sports Dad of the Year
Sports Dad of the Year recognises fathers who show up for their families, clubs and communities. Philips Water supports the program and helps us share practical information that families can use when considering water purification at home.
