Product review (5 stars): Large family loves it!
We have 12 kids (9 still in the house), and have been using the PureWash for about three months, doing an average of 2-3 loads of laundry a day.  I bought the system at Christmas. Installation was a breeze, and took all of about 5 minutes.  It is installed on our Whirlpool Duet.  We are very happy with the cleanliness of the clothes, the ability to save tons of electricity not heating the water, and the lack of detergent residue.  We have yet to find any problems that a mild amount of pre-treatment won't solve, and we have some fairly active kids.  Clothes come out looking and smelling great.  Thanks to the reviewer who pointed out that the Duet uses a little hot water even on the cold cycle. Have to get behind the machine and turn off the hot water valve...

I work for a city utilities company, and gave out rebates for commercial ozone laundry systems and, when I saw this advertised by a local store, got one immediately.  No regrets...
