The unit filters water in 3 stages and comes with a cleanable sediment filter that removes sand, silt, dirt, and other large particles.

The carbon filter eliminates chlorine while the RO membrane gets rid of TDS and microorganisms present in the water.

And just like the 31040, this system can produce up to 300 gallons of pure water per day. It also boasts a 2:1 waste to pure water ratio, meaning that for every gallon of pure water produced, 2 gallons of water go to waste.

Thankfully, it offers an optional 1:1 ratio flow restrictor that helps save 50% more waste water.

Although great for drinking and cooking water, you can customize the HydroLogic Stealth RO 300 for gardening and hydroponics.
