5-Stage Reverse Osmosis Filter


  • Keeps your reservoir’s nutrient solution stable.

  • Helps plants uptake nutrients quicker.

  • Improves root health.

  • Increases both growth and yield.


Using a very fine semi-permeable membrane, RO removes all bacteria and viruses and between 95 and 99% of contaminants, among them lead, chlorine, fluoride, arsenic, hormones, iron, nitrates, calcium, and sodium. RO also eliminates the growth of bacteria in the system because everything that the membrane has removed is automatically washed out.

The 5 stages of RO:

Stage 1: 5-micron sediment pre-filter - removes large particles like mud, rust and dirt.

Stage 2: Activated carbon pre-filter - removes ozone, pesticides, lime and chlorine.

Stage 3: Carbon block pre-filter - reduces fine sediment, any chlorine taste and the concentration of heavy metals.

Stage 4: 50 GPD TFC (thin film composite) reverse osmosis membrane - removes pesticides, herbicides, bacteria, viruses, parasites and metals.

Stage 5: Inline GAC (granular activated carbon) filter - removes organic chemicals.
