GrowoniX EX400-T Tall Reverse Osmosis Filter 400GPD w/ KDF

Growonix EX400-T Tall Reverse Osmosis System for 400 GPD

The Growonix EX400-T Tall produces 400 GPD of near-zero-ppm water and flows 17 gallons per hour at a 2:1 ratio. Its tall pre-filters carry twice the sediment and carbon media of a standard EX400, for 16,000 gallons of capacity. That means longer runs between filter changes. It is built with dual o-ring fittings and a steel pressure gauge. A manual flush valve purges salts off the membrane; flush it for 3 to 5 minutes after each use. Recovery runs at 33% and can be dialed back for lower-quality feed water.

Upgraded KDF85 Carbon and Longer Service Intervals

This unit ships with the upgraded KDF85 carbon filter. On city water it cuts chlorine and chloramine. On well water it pulls down iron, hydrogen sulfide, and heavy metals that wreck membranes. The KDF85 stage lasts about twice as long as the standard green carbon, and the tall housing stretches the interval further. Running cold or low on pressure? Add a BP-1530-38 booster pump to reach 80 PSI for more output. Higher TDS or colder water will lower production.

Key Features

• 400 GPD output: Flows 17 gallons per hour of near-zero-ppm RO water at a 2:1 ratio.
• Tall pre-filters: Twice the sediment and carbon media of a standard EX400, for 16,000-gallon capacity.
• Upgraded KDF85 carbon filter: Reduces chlorine, chloramine, iron, hydrogen sulfide, and heavy metals.
• Longer service intervals: KDF85 lasts about twice as long as green carbon, and the tall housing extends it further.
• Bacteriostatic media: Stops microbes from breeding inside the carbon stage.
• Manual flush valve: Purges salts off the membrane to extend its life.
• Steel pressure gauge: Reads system pressure so you can track performance and filter condition.
• Dual o-ring fittings: Tight, reliable connections across the housing.
• Booster-ready: Pairs with a BP-1530-38 booster pump to reach 80 PSI for more output.
