GrowoniX EX200 Reverse Osmosis Filter 200GPD

Growonix EX200 Reverse Osmosis System for 200 GPD

The Growonix EX200 produces 200 GPD of near-zero-ppm water and flows about 8.5 gallons per hour at a 2:1 ratio. It holds a nominal 96% salt rejection to bring your ppm down. It is built with dual o-ring fittings and a steel pressure gauge, so you read system pressure at a glance. A manual flush valve lets you purge salts off the membrane. Flush it for 3 to 5 minutes after each use to add membrane life. Recovery runs at 33% and can be dialed back for lower-quality feed water.

Standard Green Coconut Carbon, KDF85 Upgrade Ready

This base unit ships with the standard green coconut carbon filter, an NSF61-listed block that handles chlorine removal. It carries 8,000 gallons of capacity, or 3,000 gallons of RO water at a 2:1 ratio. On chloramine city water or well water with iron and hydrogen sulfide, step up to the KDF85 carbon filter instead. Running cold or low on pressure? Add a BP-1530 booster pump to raise system pressure to 80 PSI. Higher TDS or colder water will lower production.
