Blue.ion: HEPA performance redefined

Can a filter be more compact, more energy-efficient and more powerful than anything that has gone before? The answer is yes - through active electrification. Our white paper "Revolutionary indoor air filtration: Blue.ion from Hengst sets new standards" takes you behind the scenes of a technology that leaves conventional systems far behind and provides up to 40 times more protection against viruses and ultra-fine particles.

What you can expect in the white paper:

  • The efficiency proof: Find out how we realize full HEPA performance with 80 % less space requirement.
  • The end of the drop in performance: Discover why active polarization keeps the protective effect stable over the entire service life, while conventional filters break down after a short time.
  • Facts instead of promises: We present you with detailed evaluations of independent laboratory tests and scientific field trials.

Secure your knowledge advantage now and discover the future of air purity.
