Mantis 4 Stage 100GPD RODI System

Mantis 4-Stage RO/DI Filtration System – 100 GPD

Get ultra-pure, low-salt water with the Mantis 4-Stage RO/DI Filtration System – 100 GPD, designed for freshwater and marine aquariums, misting terrariums, and other high-purity applications.

This system is powered by a high-performance 100 gallons-per-day (GPD) reverse osmosis membrane, capable of removing up to 99% of salts, contaminants, and impurities. Supporting this core component are three large 10″ filter housings, each pre-installed with essential filtration media:

Sediment Cartridge – Captures fine particles, dirt, and debris to protect downstream filters and extend their lifespan.

Carbon Block Filter – Removes chlorine, chloramines, and organic contaminants that can harm aquatic life.

DI Resin Cartridge – Polishes the final water output by removing remaining ions for truly deionized, ultra-pure water.

The unit also features a built-in pressure gauge for easy monitoring, and a manual flush valve to maintain membrane performance and extend service life. With an impressive pure-to-waste water ratio of up to 1:1, the system ensures high efficiency and minimal water waste.

Built onto a durable, powder-coated metal bracket, the system is stable, compact, and easy to install. It measures approximately 38 x 22 x 47 cm, uses standard 1/4″ tubing, and holds approximately 600 ml of DI resin.

Whether you're a reef enthusiast or just need reliable, clean water for your setup, the Mantis 4-Stage RO/DI System delivers unmatched performance and purity—right out of the box.
