GroMax Water replacement filter GAC 10" suitable for: MINIMAX 75

The GrowMax GAC 10" activated carbon filter is the official replacement filter for the GrowMax MiniMax 75 reverse osmosis system . It serves as a second stage filter and is critical for the effective removal of chlorine, chloramines, volatile organic compounds (VOCs), pesticides, herbicides, and bad odors from the water.

Why exchange is important

Regularly changing this filter protects the sensitive RO membrane in the MiniMax 75 from premature wear and tear and ensures that your system always produces maximum clean, plant-friendly osmosis water. Chlorine significantly impairs the effectiveness of organic fertilizers or microorganisms.
