These filters should be changed every 6 months for best efficiency.

Stage1- 1x Dirt Sediment Filter (ST-01)
Stage 2- 1x Carbon Block (ST-CTO)

Our 5 Stage compact RO system comes stock with a GAC filter (Green Lable) as a stage 2 filter.

It is much the same as stage 3 in functionality so we have chosen to replace it with an extra stage 3 filter.

This will save you as a customer as the cartridges are a lower cost and in our opinion, will produce better water through maximum chemical reduction before it reaches the membrane.
