About HHIT


During the course of the pandemic, Prospero Garcia-Gallardo's architectural studio received a number of requests from clients regarding air and surface disinfection systems that could be implemented in their businesses and homes. The only air and surface disinfection systems on the market were chemical diffusion systems, but they could have a negative impact on people's health. Conversely, there is potential for energetic disinfection systems, such as UV disinfection systems, although currently no such systems are on the market for air and surfaces.


In response, we have developed a device that is effective against biological agents, such as SARS-CoV-2, in the air in the presence of people and on uninhabited surfaces. These devices were tested by the University of Burgos, have CE marking, and are currently installed and operating in several locations in Burgos: the Civic Center of La Estación, the San Amaro Higher Polytechnic School, the Faculty of Economics, the Faculty of Education, the Vena Polytechnic School, the Faculty of Chemical Sciences, the Faculty of Law, the Rector's Office, and the Faculty of Health Sciences. In 2022, we were granted a Spanish patent.


While testing these devices, we couldn't find suitable test chambers, so we invented a test chamber and a test procedure. We were also granted a Spanish patent in 2024 and are currently working on a European patent.


During the process, we discovered that our devices were effective against most viruses, but very slow against some bacteria and fungi, because the intensity of airborne radiation could not be increased without putting people at risk. Consequently, we developed a new component that allowed our devices to operate at unlimited intensity, effective against any airborne pathogen. This was our third Spanish patent, also in 2024, and we are currently in the process of obtaining a European patent.


Our devices proved to be effective, in addition to biological agents, against a wide range of atmospheric pollutants (NO₂, O₃, VOCs, etc.) and odors (H₂S, CH₃SH, NH₃, CH₃CHO, etc.), through photolysis and photocatalysis processes.


We have also developed a new device to combat air pollutants unaffected by these processes, for which we have also applied for a patent in Spain with an extension to the European level. It is currently being processed.


Additionally, we have applied for several utility models based on theser patents, which are also currently being processed.


To work in this specific area, we founded our company, Hit Healthy Indoor Technology SLP, as a professional architectural firm registered with the official association of architects. It currently holds the following accreditations:




On October 1, 2024, we signed an agreement with the University of Burgos with the aim of initiating collaborative research projects on the study of airborne pollutants. In accordance with the provisions of this agreement, the company will furnish its aerosol test chamber, which was patented in 2024, while the university will provide a designated laboratory space and assign personnel with the requisite expertise in handling chemical and biological aerosols. Furthermore, the University of Burgos will provide scientific and technical advice throughout the process.


In order to consolidate its position in the market, the company has initially adopted a robust intellectual property strategy, giving it priority over project development and the preparation of grant applications. We have three patents granted, two in 2024, and a fourth pending, all in the field of chemical and biological air decontamination. Two of these projects have been subsidised by the Spanish Patent and Trademark Office. Should you require any further information, please contact info@hhit.es.


We have recently submitted an application for EU funding and are currently in phase 2 of the EICACCELERATOR (EISMEA) project. A decision is pending. For this project, we are collaborating with the University of Burgos and the ICCL (Castile and León Construction Institute). The objective of this project is to develop a healthy and energy-efficient indoor air quality system that is directly adapted to the complex regulatory framework for building construction, with a special focus on building renovation. A solid strategy for protecting intellectual property rights will be implemented, allowing benefits to be obtained through the exploitation of rights or direct manufacturing.


Our long-term business strategy is to establish a reputation as a leading provider of indoor air quality and building health solutions. We are committed to delivering high-quality design and adaptation services that prioritise indoor environmental health, user safety and energy efficiency.


In parallel with the development of our R&D&I projects, we also undertake reports and architectural projects. Our company specialises in the design and adaptation of buildings, with a focus on achieving high standards of indoor environmental health, ensuring user safety, and maximising energy efficiency.
