    • The reason for air pollution.

      Air pollution in hotels has been the cause of many disorders, both for guests as for the hotels themselves.

      And the main factors responsible for poor air quality are:

      Bacteria: 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 182 people were infected and 29 died. (source:

      After investigations were conducted, researchers discovered the bacteria called Legionella pneumophila, which had developed in the hotel's air conditioning system and propagated to all environments through the air, infecting people who inhaled it. However, Legionella is not the only potentially pathogenic bacteria present in the air, but this was the case which led experts to become aware of the importance of air quality in hotels.

      Mold (fungi): Infiltration and moisture are considered risk 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.

      At a hotel in Cincinnati, mold contamination resulted in expenditures (related to the hotel renovation) of around 2 million dollars! In addition, the hotel manager was seriously ill due to pneumonia acquired during the work. Another case of a famous hotel in Waikiki, Hawaii, resulted in the closure of a 347-room tower.

      Mites: Mites are directly 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;

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


      In order to promote the guests' well-being and provide them a more enjoyable stay, some measures have been adopted such as the use of recyclable materials with low emission of volatile chemical compounds; the reduction in the use of chemicals; and mainly the improvement of air quality, especially in the rooms.

      Given the increasing level of public demand not only in luxury hotel chains, but also in small establishments, the "healthy hotel" concept is becoming increasingly widespread.

      What do the hotels have to gain by investing in Airfree equipment?

      The use of Airfree purifiers provides unique advantages, since along with other cleaning measures, they are able to transform regular accommodations into "anti-allergic" environments, by reducing the amount of allergenic substances, microorganisms and ozone in the air. After this additional service, many hotels are charging a nominal fee added to the daily rate, which makes it possible to amortize the investment in the short term, increasing the profit margin in the medium- and long-term.
      See the following example:

      Additional Revenue with Airfree

      Number of rooms with Airfree;30
      Additional fee ;R$ 10,00 per day
      Number of days; 20 per month
      Additional Revenue;- R$ 6.000,00 per month


      - Spontaneous marketing – “anti-allergic rooms” generate word-of-mouth publicity spread by the customer, competitive advantages and News Press releases.
      - Increased Mark Up.
      - Less problems with mold.
      - Reduced problems with allergies and respiratory distress.
      - Reduced microbiological level in the air to meet the world's air quality standards.

      AIRFREE® AIR PURUFIERS; eliminate up to 99% of mite allergens, and help keep the air free of allergens and other micro-organisms, and they are major allies in increasing quality of life of those 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, considered a major cause of respiratory crises, 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.
