Airfree’s story is really quite unusual. The technology began being developed thanks to the initiative and creativity of a Portuguese businessman in an effort to find an effective way to ease his son’s allergy attacks.

The first prototype Airfree air purifier was developed on the basis of a naturally way of using heat to destroy airborne allergens. After successful testing at the INETI microbiological laboratory in Portugal, the idea of large-scale production of the devices began to take shape, so that more families worldwide could be able to enjoy the benefits of a simple, effective concept.

In 2004, after a few adjustments had been made to improve electronics and capacity, Airfree was born, marked by the launch of its P air purifier range, attractive and modern in design. A ground-breaking brand was on its way to conquering world markets.

Since then, Airfree has continued to grow, manufacturing a variety of models of air purifiers in Portugal, intended for use not only in the home but also geared towards trade and industry. Currently, 90 % of production is directly exported to more then 60 countries across Europe, the Americas, Asia and the Middle East.

Our Mission

“To combine the best technology and design, to turn our clients’ needs into innovative solutions for indoor atmospheres, whether for health reasons, comfort or to increase productivity.”


Airfree’s exclusive technology works by eliminating microorganisms and allergens, destroying them in a fraction of a second. Depending on the model, between 14,000 and 20,000 litres of air pass through the Airfree device every hour, treating all the air in the room in a very short space of time. The process works in much the same way as sterilising water by boiling it; when water is boiled, the microorganisms it contains are eliminated. In similar fashion, Airfree continually draws in air from the room, heating it to over 200 ºC and instantly sterilising it. The purified air is then cooled inside the device before being returned to the room. The entire process is completely silent and requires no maintenance, not even the occasional replacement of parts. All you have to do is switch the device on and leave it to get on with the job.
