The Wood’s technique

Exceptional filtration with less noise and power consumption.illustration-400px

Wood’s air purifiers have a patented filtration technique. By using ionization both in the air purifier and in the filters, Wood’s are able to reach HEPA-level filtration levels, at a fraction of the energy consumption and noise levels that comes with such a dense filter.

With the lowest possible energy consumption and noise levels, Wood’s air purifiers provide a reliable and safe protection against pollutants down to size 0,0003 mm..

  • The air is circulated in the room and drawn through the air purifier with a quiet and energy saving fan.
  • The air particles are ionized as they enter the air purifier. This increases their size, and they are also attracted to oppositely charged surfaces.
  • The Active ION HEPA filters are ionized in production. The filters attract and catch the already ionized air particles.

Active ION HEPA filter

Thanks to the patented technique, the Active ION HEPA filters can be much less dense than traditional HEPA filters, and still reach the same (or higher) filtration levels.

One Active ION HEPA filter is made up of multiple layers of pleated filter media. The gives a very large total filter area and exceptional filtration capacityactiveionhepa_400px.

Main benefits of a less dense filter:

  • Able to use quiet and energy saving fans.
  • No risk of air passing unfiltered (no leakage of particles).
