Product review (5 stars): Pure Wash laundry system for low flow washer
This is a revolutionary product.  I bought mine through Direct Buy and have ordered one for my daughter.  You use only cold water; no detergent; no fabric softener.  You save on electricity, and the cost of detergent and fabric softener.  You no longer discharge pollutants into the ground and your washed fabrics are free of chemicals.  Some stains, such as oil, must be pretreated.  I'm thrilled with my unit and the condition of my laundry, and I have tested it with some pretty harsh stains via my cats.  At 76 years and 120 pounds, I easily installed it myself, even diverting cold water to my dryer for the steam cycle.  I have extremely hard well water, even with a water softening system, so I've ordered an additional softener to go between my cold water outlet and the Pure Wash unit.
