Activated Filter Media

What if you could…

  • save on chemicals and use less of them?
  • increase your water clarity significantly without adding a clarifier?
  • NEVER have to replace your filter sand again?
  • remove more stuff from the water so that you and your chlorine have to work less?
  • greatly reduce your chances of having water problems?

Now you can with AFM®ng

Think of the filter as the “kidney” of your pool, just as your kidneys are constantly working to remove impurities from your body, your pool filter is responsible for removing impurities from the water. Think dirt, leaves and pine needles in the pool.

The more efficient and optimized your filtration is, the lower your consumption of chemical products and the amount of time and effort you need to spend on maintaining your pool will decrease.

Now’s the time to upgrade your sand filter to the best filtration available on the market!

AFM®ng is the result of 35 years of research and development by Dryden Aqua. Made from brown and green glass, it is exposed to a unique activation process that makes it self-sterilizing and takes its filtration capabilities to a whole new level.

This filtration media is a direct replacement for sand. Any sand filter can be retrofitted and requires no additional investment in infrastructure.
