Product review (4 stars): JUST ANOTHER GIMMICK, OR A REAL LAUNDRY HELPER AND ENVIRONMENTAL FRIEND?
First, let's lay all the cards on the table from the get-go. If you believe all reviews are from just the average Jane and John Doe and not from people who work for or are solicited or paid to write favorable reviews by the manufacturers of products, then I'll bet you still believe in the tooth fairy. Secondly, while it's true this "form of technology" has been in use in institutional/hospitals/upscale hotel applications for the past decade or two, those systems are vastly different and more sophisticated from what you're looking at here. Lastly, some reviewers base their reviews on results from their own unfortunate errors. If you want to get the real scoop on a product, especially if it seems too good to be true, then also read factual and actual tests done by recognized independent testing companies like Good Housekeeping or Consumer Reports, etc. Btw, they rate them from a "bust", a gimmick, to mediocre. However, there are some attributes that they don't address, which I will try to point out in my review. I bought one anyway, but only because I got it at a price that wouldn't break my heart if it turned out to be, well, junk.

Ill start by telling you my wife has some allergies that weve narrowed down to include dyes and perfumes in detergents and fabric softeners. Also, detergents really don't get rid of bacteria in clothes, and even though we rinse twice, the detergents and softeners just don't rinse completely out. I purchased the pureWash by Greentech Model PUREWASHv1.1HF (High Flow). These are actually sold under 3 or 4 different names, but are virtually the same product. As of this writing, these types of models are now available in a newer version from Greentech Environmental which is essentially the same, but adds a pre-filter to the system and is for use with either standard or HE washers. I want to also say, that anyone's results are very much dependent on type of washer they have and water quality (hard,iron,soft,high mineral), and using the correct model pureWash for your type of washer. Many people purchase a High Flow model, but are using a High Efficiency top loader or front loader, or a Low Flow model and they have a standard washer. WRONG! It just won't work correctly. Make sure you purchase the correct flow for your type of washer. We own a Speed Queen top loader, which is pretty much NOT an HE washer. So, I purchase the High Flow model. Our water quality is quite good, maybe a little on the harder side mineral content, but not iron laden or milky. Greentech advises using a pre-filter to any application to be on the safe side, but I opted not to. Installation was truly a breeze, and water connection simple. The instructions are very clear and easy. WARNING! After you tighten the water lines and don't see any leaks, come back and recheck several times afterwards. I thought mine were tight, no drips, only to discover it developed a drip later on that evening, so snugged it up a little more. With the unit properly installed and powered up, I turned the washer to COLD and started the washer for a first test. The pureWash clicked into action and the bubbles poured past the window in true, blue, fashion. The fragrance of the water was really fresh smelling. That's the O3 ozone in the water. I do 2 loads a week. One is darks and one is lights/wifes dainties. I proceeded using no detergents or softeners. The first wash cycle and first rinse saw the residual detergents and softeners wash out from the previous weeks wash. The last rinse was quite clean looking. As for the light colors, as a test, I purposely threw in an old flannel top that I had used to wipe the window sills with, so it was covered in a light dirt/dust. Unfortunately, not all washed out with just the pureWash. I was a little disappointed as it wasn't grease or stain. But, pureWash does acknowledge that you may still want to use a little detergent or prewash, so I washed the same 2 loads again the next week, including the not clean flannel top, but this time I used a small amount of Tide Free & Gentle, non-HE, dye and perfume free. The amount was about  to 1/3 of what we usually use. Everything came out spotless and odor free, except for that nice, clean smell of fresh.  My final verdict is that it performed pretty well, but only with a small amount help from our eco-friendly detergent. Final verdict is that it does work to some degree with aid of a small amount of detergent, and will save in hot water energy cost and detergents polluting the water. One other thing is that these O3, oxygenated, ozone systems are far more effective at killing germs and bacteria than detergents, which is important to folks with sensitive skin and infants. Thats why the big brothers to these homes systems are used in hospitals and other institutional applications. How long will it last? I can only hope past the warranty, which unfortunately seems to be honored only if it was purchased from one from one of their authorized retailers/distributors.

I give it three stars for it's washing effectiveness with a little help from detergent, but add one more star for killing germs and bacteria, energy savings, and it's eco friendliness.
