How does Intellipure's industry-leading DFS technology work?

DFS, or “electrically enhanced/stimulated air filtration” technology was developed through a U.S. military grant. It has been rigorously lab-tested and has proven to remove 99.99% at 0.007 (µm). DFS technology also guarantees greater lifetime performance.

  • Each unit is individually tested with a class 1 laser particle counter and is certified to exceed traditional HEPA filtration providing the highest level of ultrafine particle and virus removal.
  • The DFS high energy field creates a self‐contained, highly ionized state in the main filter that clusters ultrafine particles to make them larger, allowing the main filter to effectively capture ultrafine particles.
  • The DFS continually creates high energy exposure through the pleats and fibers of the main filter. This prevents organism growth in the main filter and prevents live organisms from escaping back into the air.
