Bon Del water FiltersTechnology by Nasa, Filters by Bon Del

If you've already read our history page, you know that Bon Del began when inventor Ray Ward read about the technology NASA perfected in the '70's for filtering water using a combination of granular activated carbon bound to silver.

In this section you can learn a bit more about water filtering technology in general, and Bon Del's technology specifically.

Our technology consists of these basic component pieces:

  • Granular activated carbon absorbs many impurities out of your water, and removes the bad tastes and smells
  • Silver bonded to the activated carbon inhibits bacteria growth
  • Our housings are built from plastics designed not to leach impurities into the water, and in the case of the countertop unit are augmented by a pre-filter which removes sediments before they even get into the main filter

Also in this section of our web site

You can learn the basics of the different water filter technologies (ours isn't the best for all circumstances), and even compare the pros and cons of different technologies.
