Pollutant-free water for healthy plants

Filter construction & maintenance

The Eco Grow consists of:

1. 5 micron sediment filter – retains coarse particles such as rust, sand and suspended matter
2. GAC activated carbon filter – removes chlorine, chloramines, pesticides, herbicides, VOCs, benzene, THMs, detergents and more

The filter capacity is sufficient for approximately 11,000 liters of clean water. Depending on water quality, filter replacement is recommended every 4–6 months . Replacement filter sets are available separately.
