Dean’s Water History
Dean began selling Multipure Water Filters in 1975. As time passed, he learned that sometimes it takes multiple technologies to remove every undesirable element from water, so he began researching other technologies, and subscribed to several technical water treatment publications. At this point he started his business as Aqua Alternatives. From granular carbon and compressed carbon blocks, he began to include ceramic filters, distillers, aeration systems, water softeners, and ultimately found that the best technologies for Whidbey water were ozone and oxygen systems. With most individual systems he found that no one system will treat everything. However, the oxygen system is the only one that will include as many other technologies as necessary while keeping the price constant: it is truly the only system that does everything.
