Product review (5 stars): Fantastic Product!!!
Be wary you must know if your washing machine is "low flow" or "high flow".  If you don't match the correct pureWash model to your machine, you're gonna have a bad time.  So please do go beyond knowing if your machine is HE or not.  Some HE machines fill faster than others and therefore will need a "high flow" model.

I have two pureWash units.  One for my home and one for a home I rent out.  The tenants of my rental property are thrilled at how their laundry becomes clean in only cold water with no use of detergent, thus saving them money.  I'm thrilled because the rent they pay me isn't being spent on excessive hot water sucking up my profits.

You must pre-treat certain stains.  Food coloring and ink stains need to be pre-treated.  I have not found a food stain which needs pre-treating.  I have not found any stains from hunting (blood, mud, etc.) which need pre-treating.  The pureWash system is a boon for hunters who want to remove scents from hunting garb.

I also attached a "Y" splitter with valves so I can have "pureWash water on demand".  I use this to clean surfaces and....though I am not advising one do this....I swish it in my mouth as a rinse.  It tastes and reacts a lot like diluted hydrogen peroxide and studies have shown it to have many benefits.  NEVER SWALLOW IT.

I am hoping the pureWash system may someday be integrated into a "cold water only" machine.  With a pureWash system, all the extra 'bells & whistles' are no longer necessary.  No more need for "Steam Washing" or "Sanitizing Cycles".  I just want a very basic machine with about five wash options (Delicate, Normal, Bulky, Heavy Duty and Rinse/Spin), three spin speeds and large capacity.  No more heaters, no more "Intelligent Laundry Aid Dispersal Units" and all that garbage we didn't have back in the 70s.  I say a simple solution like pureWash demands the elegance of a simple, yet highly effective, machine.
