    • Unknown dangers.

      Ozone is an allotropic form of oxygen, consisting of 3 atoms (O3), whose characteristics are: unstable gas, diamagnetic, P.E. -112°C.

      This gas, which at room temperature is blue and has a characteristic smell, is also a very strong oxidant, reacting more rapidly than O2.

      Ozone is reactive and it is able to oxidize metals such as iron, lead and arsenic. Because it is extremely reactive, it can also attack protein, destroy microorganisms, and hinder the growth of plants. It is produced naturally in the stratosphere through the photochemical action of ultraviolet rays on oxygen molecules, bringing benefits.

      On the other hand, when found in the troposphere - the lowest layer of the atmosphere - it is responsible for pollution in large urban centers.
      The tropospheric ozone is produced as a result of smoke generated by combustion engines and power generation plants.

      In fact, industrial emissions and automobile exhaust emit a range of nitrous oxide gases (NOx) and volatile organic compounds (VOC), by-products of gas and coal combustion. Oxygen atoms released by NOx and VOC attack oxygen molecules and form ozone through the action of sunlight.

      Ozone generators are sold as air cleaners and intentionally produce this gas, freeing some of it as a by-product of this process. However, high concentrations of ozone react with the organic material inside and outside the body. When inhaled, ozone can damage the lungs, cause chest pain, coughing, shortness of breath, and throat irritation. It can even cause chronic respiratory diseases, worsen diseases such as asthma and bronchitis, and make people more susceptible to respiratory infections.

      AIRFREE® PURUFIERS are the only ones that reduce the amount of ozone in the air. They are up to 99% efficient in destroying bacteria, viruses, airborne mold spores, mite and dust allergens, and other airborne pollutants, and they are major allies in increasing the quality of life of people who suffer from allergies.

      How do they work?
      They dramatically reduce air pollution by burning the microorganisms. As a result, the contaminated air is drawn into the Airfree® ceramic core and destroyed at high temperatures. This air purification cycle is silent, requires no maintenance and is guaranteed by numerous tests.


      Efficient - Tested and approved in real environments (no simulations) at the best institutes around the world. Airfree® destroys any microorganism passing through the ceramic sterilizer, regardless of its size or hazard level.

      Silent - Completely noiseless.

      Exclusive - Internationally patented technology that is exclusive to Airfree® products, the only one that also reduces ozone concentrations.

      Economic - No part replacement expenses or significant energy costs, since Airfree® consumes only 48w per hour.

      Practical - Turn it on and forget about it, since the devices require no maintenance or cleaning.

      No contraindications – Completely natural process which uses no radiation, chemical or toxic products, and do not interfere with the temperature or humidity of the environment.

      Note! It does not emit ozone gas, which as previously seen, are considered a major cause of respiratory crises such as asthma, and which may also destroy lung tissue.

  • FAQ´S
    • 1. Are there any side effects?
      No. Airfree’s new technology uses heat to purify the air. No side effects, no emissions, NO IONS, nor new particles are generated. Airfree® should be used in all homes and offices, quietly, constantly, and efficiently purifying the air.

      2. 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 its heated ceramic core.

      3. 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 by dust mite feces that trigger respiratory allergies.

      4. How does Airfree eliminate fungi?
      As mentioned before, Airfree eliminates airborne microorganisms included fungi and spores. By eliminating spores new colonies are unlikely to develop, representing less future airborne spores.

      5. How does Airfree® destroy viruses?
      Those microscopic microorganisms are easily eliminated inside Airfree’s ceramic core capillaries. The temperature inside of Aifree’s capillaries is much higher than required to incinerate them. Airfree® is your greatest ally in respiratory disease prevention.

      6. Does Airfree reduce tobacco smell?
      Yes, Airfree reduces any kind of organic smell in the ambience including tobacco.

      7. 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.

      8. Does Airfree heat up a room?
      No. Airfree does not noticeable increase room temperature. To have an idea 2 Airfrees plugged in the same room will contribute as much heat as the presence of one adult in that same room.

      9. Does Airfree provoke any change in room’s the relative humidity?

      10. Does Airfree need filter replacement?

      11. Does Airfree consume a lot of energy?
      No. Airfree’s consumption is just 52 Watts for P150, 50 Watts for P125, 48 Watts for P80, 45 Watts for P60, 50 Watts for E125, 48 Watts for E80 , 45 Watts for E60 and 40 Watts for E40.

      12. Where do the microorganisms go after they are destroyed?
      As all living organisms, microorganisms and their products are basically composed of carbon, oxygen and nitrogen. Since Airfree® reaches approx. 200º C, all the components are supposed to suffer a combustion process, which liberates carbon dioxide (the same product released by our respiration) and water. Some carbon (or ashes) may remain in the process. If there is some residual allergen left, we might consider that they suffer denaturation, a process resulting in loss of conformation and function. It should be noted that we are talking about reactions that occur in a microscopic level, so all these processes or by-products won’t be perceived. In this case, there is no need to worry about maintenance.
