Reproducing natural mechanisms, Therapy Air® iOn is as multifunctional, as technically advanced and as stylish as it is easy to use. It will allow you to enjoy pure, forest-like air all around you.

Our pioneering five-filter technology generates about 220,000 negative ions per cm3, which is equivalent to the number of ions found in some of the healthiest environments on earth.

It solves some of the greatest problems of our modern lifestyles including an environment that increasingly provokes more illnesses, chronic flu-like conditions, air pollution and health hazards in the home that can cause allergies, respiratory and coronary diseases and cancer.


The Zepter Therapy Air® iOn is fitted with 5 different air-purification filters:

1. ANTISTATIC FILTER: Removes larger particles of dust, mould, hair, dandruff, and pet hair;

2. ANTIBACTERIAL FILTER: Removes the remaining small particles of dust, bacteria larger than 1 micron, and pollen, while protecting the HEPA-filter located next to it.

3. HEPA-FILTER: Eliminates the tiniest particles of dust and tobacco smoke while the antibacterial thiabendazole, (an organic antibacterial compound), removes bacilli, mould spores and germs thus preventing the risk of infection;

4. ANTI-ALLERGENIC FILTER: A mixture of silver, apatite (a mineral) and an antibacterial agent that is especially effective against Legionella bacteria that are particularly dangerous for babies. The filter contains an extract of ginkgo biloba leaves that are very effectively used for asthma, lung diseases and circulation problems and to eliminate the causes of allergies, flu viruses and bacteria;

5. ACTIVATED-CARBON FILTER: Eliminates unpleasant food smells, toxic gases and other odours thanks to its high absorption characteristics.

Purified air enters the module containing the inbuilt ion generator where it is enriched with negative ions.


Silent and efficacious, the Therapy Air iOn unit consists of sophisticated mechanisms and special individual components which enable it to run in a quite simple way:

  • the ventilator sucks the air in from the room and ducts it into the filter system;
  • the purified air then passes through the negative ion generator and is enriched with negative ions;
  • when the negative ion concentration is high enough, the negative ions and the positively charged dust and microbiological particles floating in the air are mutually attracted;
  • the dust particles become heavier and, before falling to the ground, are completely eliminated by the Therapy Air® iOn filter system;
  • purified air is then ducted to the surrounding atmosphere.


Negative ions are oxygen atoms with extra electron. They are created in nature under influence of water, air, sunlight and Earth inherent radiation. The biggest concentration of negative ions is near waterfalls, moving water, oceans, on the beach, in forests and after the thunderstorm.

Negative ions can neutralise positive ions and the harm they can cause the human body thus rebalancing the bio-energetic fields and offering a consequent improvement of all bodily functions and energy levels.
