    • The indoor spaces that contaminate us!

      Currently we can observe the increasing tendency to construct buildings that are closed in, with little open spaces for ventilation, which use less energy to maintain air circulation and cooling.

      However, as this type of construction solves the energy consumption problem, by reducing the inflow of outside air it accumulates chemical and biological pollutants generated in the internal environment, since the air renewal rate is not sufficient.

      Chemical pollutants - such as carbon monoxide and carbon dioxide (CO and CO2) , ammonia, sulfur dioxide and formaldehyde produced inside the buildings from construction materials, cleaning materials, cigarette smoke, photocopiers and the even human metabolism -, and biological pollutants - such as fungi, algae, protozoa, bacteria and dust mites, whose proliferation is favored by improper cleaning of carpets, rugs and curtains -, were the cause of what is conventionally called Sick Building Syndrome – SBS.

      The Sick Building Syndrome refers to the cause and effect relationship of environmental conditions observed in indoor areas with reduced air exchange, and the various levels of aggression to the health of its occupants as a result of physical, chemical and/or microbiological pollution sources.

      In 1982, WHO - World Health Organization - recognized the existence of Sick Building Syndrome when it was proven that air pollution inside a hotel in Philadelphia was responsible for 182 cases of pneumonia and for the death of 29 people.

      A building is considered "sick" when about 20% of its occupants exhibit transient symptoms associated with the time spent inside such building, which tend to disappear after short periods away from it. In some cases, leaving the place is enough to make the symptoms disappear. The main symptoms include irritated eyes, nose, skin and throat, headaches, fatigue, lack of concentration, and nausea, among others.

      Other factors associated with Sick Building Syndrome are increased absenteeism rates and reduced productivity, as well as the quality of life of workers exposed to an environment that is unsuitable for occupation.

      Thus, the indoor air quality assumed an important role, not only in public health issues, but also in relation to Occupational Health.

      Learn about the main responsible factors:


      In 1976, U.S. officials were surprised by a new species of bacteria responsible for the onset of pneumonia in a group of World War II veterans. More than four thousand veterans were affected while participating in an American Legion Conference at a hotel in Philadelphia, where two hundred people were infected and thirty-four died.

      Mold (fungi)

      Infiltration and moisture are predisposing factors to the onset of mold. Mold colonies spread releasing invisible particles in the air called spores, which when inhaled may trigger allergies (approximately 80% of those who are allergic are sensitive to mold) and even infectious diseases.


      Mites are highly related to respiratory allergies and asthma. These microorganisms are found mainly in carpets, pillows and mattresses, and they prefer humid places that are rich in human skin desquamation. The waste produced by these animals contains substances that trigger allergies, and making the bed or vacuuming the floor may increase up to 1,000 times the concentration of these substances in the air. Even high-efficacy vacuum cleaners seem to be unable to remove them. (read about cleaning information at

      Chemical agents

      They are also responsible for poor air quality in offices. Cleaning products, tobacco and even perfumes can cause irritation to the respiratory tract. In order to mitigate the odors generated by the products, many offices use ozone generators. However, ozone is a gas that can cause irritation to eyes, nose, throat and lungs - and prolonged exposure can lead to permanent reduction in lung capacity. Children, especially those who suffer from asthma, are more susceptible to this gas.

      AIRFREE® PURIFIERS are up to 99% efficient in destroying airborne mold spores, bacteria, viruses, ozone, mite and dust allergens, and other airborne allergens such as those derived from animals and pollen, and they are major allies in increasing quality of life through the air we breathe.

      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.

      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: They do not emit ozone gas, 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.
