What the Hydro Logic Stealth RO 150 Actually Produces
Three stages, in this order: a sediment pre-filter, a green coconut carbon filter, then the reverse osmosis membrane. Output is up to 150 GPD and the result is a reduction in total dissolved solids of up to 98%. The GPD figure carries conditions, and they matter more than the figure does. Flow rates are based on source water at 65 psi, 77 degrees Fahrenheit and 500 ppm. Colder water, softer pressure or a higher inlet reading all cut output, and a booster pump is the usual answer to the pressure half. The unit measures 18.5 in high by 16 in wide and 6 in deep, and weighs 10.8 lbs dry. In the box are three tubing runs: 8 ft of 3/8 in inlet line, 8 ft of 1/4 in drain line and 5 ft of 1/4 in product line. The Membrane Power Flush Kit comes with it as standard, which is the part that extends membrane life rather than replacing it. An automatic shut-off stops production when the reservoir backs up. The manufacturer part number is HGC728801 and the barcode is 812111010713.
Stealth RO 150 Replacement Filters and When They Fall Due
Each stage runs to its own clock, and mixing them up is how people end up pushing dirty water at a membrane. The sediment filter is cleanable, so rinse it regularly and change it once a year. The green coconut carbon filter goes at 1,250 gallons of purified water. The membrane itself lasts between six months and two years. Which end you get depends on input water and how hard the system runs. Housings are a wear item too, and the interval there is three years. Two carbon upgrades exist if your water justifies them. A ChloraShield filter runs to 1,500 gallons, and a KDF85 catalytic carbon filter to 2,000. A de-ionisation post-filter is also available, rated to 7,500 ppm of capacity, for growers chasing the last few points of purity. The other number worth planning around is waste. This series is rated at 50% water savings against comparable systems, with a choice of a 1:1 or a 2:1 flow restrictor. That choice is what sets how many gallons go to drain for every gallon that reaches your tank.
