Puronics is featured in a new NASA Spinoff article! Here’s the part about Puronics’ SilverShield® technology.
“In the 1970s, Arizona inventor Ray Ward requested a technical information package from NASA based on the silver ion system built for the shuttle, which he used to build a prototype tap-water filter. Ward went on to found the Bon Del and Ambassador lines of water filters, which became a $50 million-a-year business. Along the way he also got some help from water treatment company Ionics Inc.
That company, now known as Puronics, later used the NASA technology Ward had introduced it to as a starting point for a water softener that wouldn’t breed bacteria.
Today Puronics, headquartered in Livermore, California, sells several lines of whole-house units incorporating the technology, which it calls SilverShield, each with different features and price points. Silver particles in the devices’ filter beds prevent them from breeding bacteria.
Company CEO Scott Batiste says the home units with SilverShield remain the company’s core products, accounting for about 70 percent of its overall business, and the product line has been doing 15 to 20 percent more business each year lately.
‘I think it’s a real testament to this technology that we’ve been using it since the late ’80s, early ’90s, and it’s still a growing product line,’ he says. ‘I think NASA should be proud of that, and of course we’re excited about it.'”
