Product review (3 stars): Updated 12/15  -  Easy to hook up
Easy to hook up  and nothing to do after that except keep your washer on COLD water.

The product pitch is a bit deceptive - be sure to carefully review the feedback from those that are not getting the results promised.

We are on city water in a mountain environment - our water is very good and no softener is needed.  Yearly water reports show our water is very clean and simple.

The product seems to work good for most loads.  Office clothes and those that are not normally terribly dirty come clean and smell fresh.  For dirty items/spots, a pre-treatment is necessary but does not always work (you might need to rub some detergent into the area).  My front loading washer smells VERY fresh.

Whites seem to be a bit more of an issue because they have been becoming dull and dingy.  I have started adding some bleach to the load and that doesnt seem to be enough for socks.  Dish clothes and towels look old and stained in no time.  A Y-fitting into the hot water inlet may be needed to use warm water in the machine (which defeats the purpose of the system).

Powders do not dissolve well in the cold water, so if detergent is needed you will have to use a liquid.

I like the product and do recommend it for basic, standard laundry that needs to be refreshed instead of cleaned.  This works well in our home with no children.

The above was originally posted December 2013.  Update as of December 2015:

Half of the unit died in July 2015, but I keep using it.  I hate that I spent that much money and half of it died after a year and a half.  We do not do a lot of laundry (no kids), so it was not abused.

Some things I learned to hopefully help others with this unit:
Some detergent is always needed, unless you are freshening something that was stuffed in a drawer for the last year.
Adding in baking soda with the wash helped the detergent work even better.
Adding baking soda in the rinse cycle really enhanced that fresh sent (sheets, towels).
Whites require warm water - ALWAYS.
My washing habits have returned to pre-pure-Wash days.

When it is completely dead, I won't purchase another because of the cost.  While it does leave a nice, clean scent, I can go back to using just baking soda in the rinse cycle.
