Under Sink Water Filter Systems

• 3-stage filtration: chlorine, sediment, taste and odour.
• 4-stage PFAS-focused filtration: selected PFAS reduction and alkaline conditioning.
• 5-stage alkaline RO: reverse osmosis with remineralisation.
• 6-stage hydrogen RO: reverse osmosis with a hydrogen stage.

Carbon commonly treats chlorine, taste and odour. Reverse osmosis adds membrane treatment for dissolved substances. Compare the complete model’s tested performance for your particular concerns.

Cupboard dimensions, plumbing, pressure, tap choice and maintenance access. RO systems also require consideration of a drain connection and any storage tank.

Ask for the system, tap and installation inclusions, plus cartridge prices and replacement intervals. This gives you a clearer picture of the ongoing cost.

Under-sink filtration treats a kitchen outlet. Whole-house filtration treats the incoming supply for multiple outlets. The two options serve different purposes.
