Hydrologic Filters - Evolution-RO100 Green Coco Carbon/KDF Filter

Hydrologic Filters - Evolution-RO100 Green Coco Carbon/KDF Filter is a replacement carbon pre-filter for Evolution-RO reverse osmosis water filtration, built to help maintain cleaner incoming water.

This carbon pre-filter targets sand, silt, dirt, rust particles, and other sediments while reducing chlorine, chloramines, iron, and sulfur before water reaches the reverse osmosis membranes. For growers who rely on consistent, cleaner water, that upstream filtration helps keep water quality more stable from start to finish.

The “green coco” design refers to a green coconut carbon style filter block made for high absorption. Its microporous structure is designed for strong adsorption, and the block format is built to keep filtration performance steady over its service life. This is a practical fit when you want a carbon pre-filter that’s focused on dependable contaminant reduction rather than extra add-ons or complicated features.

This replacement carbon/KDF filter is suited for gardeners and indoor growers who want cleaner source water for reservoirs, irrigation, and general water preparation, especially in places where chlorine or chloramines are part of the local supply or where well-water issues can show up as sediment and mineral-related impurities. If your goal is to keep the water going into your system cleaner and more consistent, this pre-filter is a straightforward, purpose-built step in that direction.
