    • Airfree Agro: Indispensable!

      When the indoor air quality is poor, health problems such as allergies, asthma and various cardio-respiratory problems occur. This is true both for humans and for animals!
      This is what happens when it comes to pigs:

      The dramatic reduction of air contaminants in critical areas is ensured by using Airfree Agro. In fact, the air quality in facilities equipped with this device provides increased productivity, verifying that each piglet has more than one extra pound during the 22-day lactation period.


      A study conducted in the UK found that pigs prefer locations with clean air, in contrast to the contaminated air with ammonia (Smith et ai., 1996). In 2002, another study confirmed these data (Wathes et ai., 2002). In addition to ammonia, originating from the animals' urine, carbon monoxide, fungi spores and bacteria are the most important pollutants (Heber et, 1988; Maghirang et al, 1996), as well as those originating from the animal itself - dry powder, waste and fermented feed (Donham et ai., 1982).

      A study conducted in Portugal from 1985 to 1995, involving about 50 farms and 10,000 female pigs, detected several risk factors, considering a10 ppm NH3 limit acceptable (Perestrelo e col., 2006). These contaminants can penetrate the pulmonary alveoli causing respiratory problems in pigs and workers. In 1995, a survey showed that the airborne concentration of the bacteria Streptococcus spp is directly related to pleurisy (the thick pleura lining on the entire lung surface) in pigs (Skirrow et ai., 1995). Another study found a negative effect on the health of workers such as fever, headache, muscle ache, coughing and irritation of nose, throat and eyes, shortness of breath and chest tightness due to high doses of inhaled dust (Donham, 1999).

      A large source of microorganisms derive from animals and their feces. In one study, 72 species of bacteria and fungi were found where pigs lived, in contrast to only 6 species in places where there were no animals (Martin et al., 1996). Another way to measure the bacteria emitted by aerosol is measuring the endotoxin present in the cell wall of most bacteria. The endotoxin concentration in places where pigs are confined may be 10 to 60 times greater than the recommended levels for the workplace (Backstrom et al., 1996). Likewise, the concentration of markers for fungi at these locations may be doubled compared to other areas.(Jolie et al., 1996).


      In addition to increasing each animal's weight, there is a noticeable reduction in stress of piglets in units protected with AirfreeAGRO. Piglets confined in these areas are noticeably quieter, resulting in a reduced mortality rate due to a decrease in crushing.

      And this weight increase can be attributed to the reduction of energy consumed by the pigs, as they are less agitated and free from infection.

      In addition, AirfreeAGRO also maintains the environment practically odorless due to the destruction of organic substances in the air.

      Advantages of this device:

      - Eliminates viruses and bacteria, reducing the use of drugs;

      - Reduces the mortality rate of birds and other animals;
      - Increases the conversion rate;
      - Reduces mold, fungus, mildew and dust mites;

      - Decreases the tropospheric ozone;

      -Improves the scent at the environment;

      - Reduces respiratory diseases, decreasing the stress among the pigs and allowing them to breathe freely;

      - Provides reduced investment per pavilion, quickly depreciable in a few flocks and productions, resulting in a healthier product to the final consumer.

      Furthermore, the Indoor Air Quality benefits the animals as well as employees. Thus, it reduces absenteeism and increases productivity, as it happens in offices protected by the Airfree system.

      How does it work?

      It dramatically reduces 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.

  • 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.
