Reverse osmosis water filter buying guide

Sediment filtration, carbon filtration, a reverse osmosis membrane and remineralisation do different jobs. Some cartridges combine functions. Read the actual stage list and installation requirements on each product page; stage count alone is not a performance ranking.

This model uses sediment and carbon pre-filtration, a reverse osmosis membrane, then calcite remineralisation with carbon polishing. Its description gives a typical pH range of approximately 7–8, with the result varying by feed water and operating conditions.

$799 supplied & installed, including GST. View the FSA 5-stage alkaline under-sink RO system and options. Ordered in for you — arrives in 5–10 days.

The 5-stage alkaline model uses magnesium remineralisation and coconut carbon polishing after the RO membrane. Compare its listed cartridges, dimensions and feed-water requirements. An extra stage does not, by itself, establish better contaminant reduction.

This model uses cartridges that twist out for replacement, with a combined carbon and calcium finishing cartridge. Check the space needed to reach and remove the cartridges, and the minimum feed-pressure requirements on its product page.

$864 supplied & installed, including GST. View the compact FSA 3-stage alkaline RO system and options. Ordered in for you — arrives in 5–10 days.

The compact model uses inline quick-connect filters and combines carbon polishing and mineral filtration in its final cartridge. Allow for the complete installed footprint, including the tank, connections and space to replace the cartridges.

Check cupboard space, the water connection, tank size and the drinking-water tap arrangement. Do not apply one model’s pressure limits or cartridge intervals to another model. Ask us to check suitability before ordering if you are unsure.

These are supplied-and-installed totals for the base configurations. Options can change the final total. Read the under-sink installation cost guide for the difference between buying a system from TapLife and supplying your own. Compare under-sink and whole-home filtration if you are choosing where to filter your water.
