One way to cut down on your use of disposable plastic water bottles is to install a reverse osmosis water filtering system. Options range from those that sit on top of your counter to those that slide under your sink.
Accreditation status should be taken into account as a primary consideration when evaluating various reverse osmosis systems. National Sanitation Foundation Global Water Program Director Rick Andrew recommends choosing a reverse osmosis system that has been independently tested and certified to remove the toxins that are posing the greatest threat to the public water supply. He explains that certification and testing guarantee the product’s safety and durability and that it will treat water as promised by the manufacturer.
To find the best reverse osmosis systems, we considered not only the flavor of the water they generate, but also their size, speed, wastewater generation, and simplicity of installation. Also, we prioritized systems that have received accreditation from the National Sanitation Foundation (NSF) or the Water Quality Association (WQA).
