1. How do I know if Airfree® is no longer working?

Check the top lid, if cold the sterilisation system is not working. Please connect it to another outlet and make sure the unit is in its vertical position for at least 1 minute.

2. Are there any side effects?

No. Airfree®’s new technology uses heat to purify the air with meaningless heat contribution to the room. No side effects, no emissions, NO IONS, nor new particles are generated. Airfree® can be used in homes and offices, quietly, constantly, and efficiently purifying the air.

3. How do I shut the Night Light or the multi-colour Night Light off?

Press the sensor touch button repeatedly to adjust the night light intensity or turn it off.

4. The top lights are blinking. What does that mean?

On models with top lights it indicates that Airfree® is not correctly placed. Please make sure the device is in its vertical position.

5. Can I install Airfree® in my walking closet?

Yes if larger than 2x2 meters (4 m² or 10 m³). Otherwise it might warm up the closet.

6. Can I use Airfree® in air conditioned rooms?


7. Can I place Airfree® at the corridor to reach adjacent rooms?

No. Airfree® will just reduce air pollution in the corridor’s area.

8. Can I place Airfree® in a closed room?

Yes. Please remember such a room must have at least 4 m² (10 m³).

9. Should I turn off Airfree® when I leave house?

To achieve best performance we recommend to keep Airfree® always on. Turning the unit off will stop the sterilisation process allowing the room contamination to grow.

10. Can I change Airfree® from one room to another?

Airfree® must always be plugged in the same room 24 hours a day. Airfree’s patented technology works gradually so, when removing it to another room the contamination in the original room will start to increase.

11. Does CADR measure the effectiveness of the Airfree®?

Not at all. CADR is not designed to test the Airfree® technology. The AHAM seal
(usually found on the back of an air cleaner’s box) lists three Clean Air Delivery Rate (CADR) numbers: one for tobacco smoke, one for pollen and one for dust. The CADR indicates volume of filtered air delivered by an air cleaner. The reason why CADR is not designed for Airfree® is because Airfree® does not filter but destroys microorganisms instead, such reduction of bacteria, moulds, viruses and other microorganisms can only be measured after air sample incubation in a microbiology lab.

Airfree® destroys (not trap or attract to other surface) any microorganism regardless of how small they might be. 99.99% of all microorganisms are fully destroyed when passing through the Airfree® patented ceramic core.

12. What happens if Airfree® is disconnected or there was a blackout?

Airfree® will take approximately the same time to recover the previous reduced contamination level.

13. Does Airfree® eliminate bacteria and viruses?

Yes. Unlike the air filters in the market Airfree® is more efficient with the smallest microorganisms as they are easily carried by Airfree®’s airflow into the sterilising TSS™ ceramic core. Please check the independent bacteria and virus tests at our website.

14. How does Airfree® destroy dust mites?

Mould reduction in the environment causes reduction in the mould dependant dust mite population. Airfree® also destroys the harmful toxins and fungus freed into the air by dust mite feces and skeletons that trigger respiratory allergies and asthma.

15. How does Airfree® eliminate fungi and moulds?

As mentioned before, Airfree® eliminates airborne microorganisms there included moulds, fungi and spores. By eliminating spores new mould colonies are unlikely to develop, representing less future airborne mould spores. Please check the independent mould tests at our website.

16. Does Airfree® reduce tobacco smell?


17. How does Airfree® destroy viruses?

Those microscopic microorganisms are easily eliminated inside Airfree®’s ceramic core capillaries. Contrary to other technologies the smallest the microorganisms the easiest they are destroyed inside the TSS™ ceramic core capillaries. Please check the independent virus test at our website.

18. Does Airfree® make any humidity level change in the room?


19. Does Airfree® release any gas or chemical product?

No. Airfree®’s sterilisation process is natural. Please check our website for conclusive tests regarding particles and ozone.

20. Does Airfree® heat up a room?

Airfree® does not make any noticeable increase in the room temperature. Just for comparison two Airfree® devices plugged in the same room will contribute as much heat as one 70 kg adult.

21. Does Airfree® need filter replacement?


22. Does Airfree® Night Light interfere with Airfree® sterilising function?

No. The Night Light has an aesthetic effect and may simply be used as a Night Light in children or newborn bedrooms.

23. Where do the microorganisms go after they are destroyed?

All living microorganisms are basically composed by carbon, oxygen an nitrogen. Since Airfree® reaches nearly 200 °C, all the components decompose into carbone dioxide (the same product released by our respiration) and water. Some carbon (or microscopic ashes) may remain inside the device or over the top lid during the process. It should be noted that all happens in a microscopic level, so all those residues are a very small fraction of the microorganisms original microscopic size, in other words meaningless.

24. How does the multi-colour Night Light work?

This function offers 10 adjustable light colours, which are Red, Rose, Violet, Blue, Light Blue, Green, Yellow Orange, Brown and Grey. Choose your favorite Night Light colour and its intensity or simply choose for the random mode and let the colours change softly.
