Consumers expect their home appliances (including refrigerators, coffee machines, washing machines, water heaters, and dishwashers) as well as their business appliances (including vending machines, commercial coffee makers, drinking fountains, and water coolers) to consistently deliver high quality products. Process fluids including water for washing, rinsing, and cooking as well as consumed fluids including drinking water, ice, tea, coffee, and soup can be strongly influenced by the quality of the water entering into the appliance environment. Treated water delivered from an appliance should maximize product quality by minimizing the delivery of a wide range of harmful contaminants entering into or generated within an appliance. Although many of these chemical contaminants may affect the consumer's perception of the water, either with off-tastes or odors, the consumption of potentially harmful microorganisms may go unnoticed. The filtration technologies must also deliver consistent and high quality fluids at the lowest capital and operating costs possible to ensure the appliance can be sold at competitive prices. This paper will present the current and projected requirements for high quality fluid delivery in a wide range of appliance environments, as well as the technical and economic strategies involved in the successful application of advanced filtration technologies into appliance environments.
