HydroLogic Purification Systems Stealth 150 GPD RO150 Reverse Osmosis Filter with Upgraded KDF Filter (HL136012)

The review claiming it used a ton of water did not read the directions, I guarantee it. I kept that review in the back of my mind while putting mine together. If you follow the directions, it has you close a valve after flushing the system initially that makes it 2:1 and then it is good to go. If you skip that step, ya, it is setup to flush water through it quickly and not to filter. Classic user error being blamed on the product.Anyways - I thought it was easy to setup and the filter quality is great. All the connections are high quality and feel built to last. No leaks or anything. Great product.

This RO system works perfect. Took my well water from 125ppm down to only 5ppm. Installation was straight forward as well.

I did a lot of reading and research before I purchased this unit. I decided to go with hydro logic because they also have the option of a cold water/ low pressure membrane if my well/pump combo couldn't provide the same temp and pressure as city water. Also, waste was a primary concern being on a well. I couldn't run it dry in the summer trying to water my plants. This unit as shipped advertises 1:1, but I was less than optimistic about achieving this.I set the unit up in my basement off a service tap spigot and mounted it to the wall. Because my well runs on a 30/50 switch and the unit requires a minimum of 60psi, I installed an aquatec 8800 booster pump between the spigot and the Stealth R/O. Pressure was a little high off the booster to start, but the 8800 has an adjustment screw on top and I was able to back it down to 75psi. From there it goes into the Stealth R/O at about 58-62 degrees. I also installed an aquatec permeate pump to the system. It uses the brine water as a hydraulic pump to apply vacuum to the output line increasing the efficiency of the R/O. From there it goes into a pressure switch for my pump and from there to a float valve in a 5 gallon bucket for collecting clean water.My first run after flushing for the half hour recommended I filled the bucket with 4 1/2 gallons of fresh water producing approximately 3/4 as much waste water. I just looked into both buckets at the same time after it shut off and approximated. Either way it was less than the volume of water produced, and far better than my expectations. The water had a TDS reading of 1ppm, and a PH of 8. My well is very alkaline already so I'm not surprised.All together I'm very satisfied with my results and there isn't a single product in this setup I wouldn't recommend!

This r/o unit was purchased to produce high quality water for watering my orchid collection. I have it set for higher water/filter saving refuse run-off, and it takes approximately an hour to fill a 3 1/2 gallon container. A little slower going than I had hoped, but it fulfills its purpose.

As our city water is laden with salts, I needed this R/O system for hydroponic gardening. I built a portable “T” support stand from 2x4s for the filter setup and this worked out perfectly! Now I don’t have to depend on rainwater for my vegetables.

Very simple: The filter arrived to me with a broken part. The card in the box had instructions to not contact the vendor, but instead to contact Hydro-Logic. They were no help and only a wasted my time. They do not seem to stand by their products. If a brand is going to put literature in the box stating to contact them if there's an issue, then why wouldn't they be prepared to actually help? Unfortunately, Arcadia INTL (the vendor I purchased this from on Amazon) and Amazon itself made the refund and return process a nightmare. Very disheartening.

So far it works very well. Easy to setup and use. I have only run it enough to get about 300 gallons of product, but don't expect it to slow down anytime soon. I'm hoping to get about 2000 gallons of product before needing to change the filters. Amazing what kind of sediment is coming out of tap water.

It was easy to set up and it works perfect. I have zero ppm’s. Love it.
