Brand: GrowMax Water
GrowMax Water Replacement Filters Compatible with HydroLogic Systems
GrowMax Water replacement filters and RO membranes compatible with HydroLogic Stealth-RO, smallBoy, TALLBoy, Pre-Evolution and Evolution-RO systems cover every treatment stage: pleated and poly spun sediment pre-filters, green coconut shell carbon blocks, KDF85/catalytic carbon upgrade filters and dry-shipped RO membranes. Select the filter that matches your system and stage from the options below.
Replacing sediment and carbon stages on schedule protects RO membranes and restores flow. When changing the carbon filter on an Evolution-RO, remove the membranes and flush the system for at least 10 minutes with the new carbon installed before reinstalling them.

Key Features
- Green coconut shell carbon blocks reduce chlorine and VOCs, filter down to 10 microns and do not release carbon fines
- KDF85/catalytic carbon reduces chlorine, chloramines, sulfur, iron and heavy metals and suits well water; in Stealth-RO and smallBoy service it lasts about twice as long as the standard carbon block
- Poly spun sediment filters capture particles down to 5 microns and suit city or well water
- Pleated sediment filters use polyester/polyester-plus cellulose media with pliable PVC end caps and can be rinsed between changes
- RO membranes ship dry and reject up to 95%+ of total dissolved solids
- 12" membrane rated up to 150 GPD at 60 psi, 77 deg F and 500 ppm feed water; also the replacement membrane for GrowMax Power Grow 500, Mega Grow 1000 and EC Eliminator
- Published change intervals: 10" carbon every 1,250 gal (Stealth-RO) or 3,000 gal (smallBoy); 10" KDF85 every 2,000 gal (Stealth-RO) or 6,000 gal (smallBoy); poly spun sediment every 3,000 gal; 20" carbon and 10" x 4.5" KDF85 every 7,500 gal; 17" carbon every 2,000 gal; pleated sediment every 6 to 12 months; 17" membranes every 6 months to 2 years
