The air ioniser from Klima-Therm can be mounted in any air conditioning system, in any building, to protect occupants from dangerous pathogens, while improving their comfort.

The product is safe, low maintenance, easy-to-install, energy efficient and highly effective on a wide range of particulate matter, bacteria and viruses including COVID-19.

In short, it is a great air purification solution at an affordable price.


As air passes over the ioniser, millions of positively and negatively charged ions are formed – just like in the natural environment. These ‘bipolar’ ions disperse into the occupied space through the duct system, attacking airborne contaminants where they cause the most problems for occupants.


There is solid proof that air ionisation technology works. Tests conducted by the Spanish government show a reduction in a coronavirus surrogate by 99% airborne and 80% on surfaces in 10 minutes.

Testing on air ionisation conducted by a specialist HVAC company based in Madrid, backed by the Spanish Ministry of Defence Biological Laboratory in Spain, showed a reduction of ‘MS2 bacteriophage’ – a surrogate for COVID-19.

The research tests were conducted in a Madrid hotel converted into a residence and confinement centre for medical staff during the pandemic.

An ioniser was installed in the fan coil unit supply air duct that delivered air to the test space. The bacteriophage MS2 was then nebulised into the test space. A significant reduction of the bacteriophage was obtained in the air that was ionised. This corresponded to a 99% reduction after only 10 minutes of exposure to ionisation.

Tests showed a reduction in surface MS2 bacteriophage of nearly 80% after 10 minutes between the test with and without ionisation.


Air ionisers have already proved themselves in a wide range of applications including the prestigious three Michelin star Sketch restaurant in Mayfair, London, which has installed bipolar ionisation units throughout its ventilation system to capture and neutralise airborne particles, including COVID-19.

The air purification technology has also been fitted in a luxurious five-star hotel in London; the 215-room Ritz-Carlton Paradise Valley hotel in Scottsdale, Arizona; the newly renovated historic 350-room Hotel Paso del Norte in El Paso, Texas; and the new TWA Hotel at John F. Kennedy International Airport in New York, as well as several other landmark developments across a range of sectors in the US and elsewhere.


Klima-Therm is one of the first companies to introduce air ionisers into the UK to protect against COVID-19 and other potentially dangerous airborne particles.
