This technology has been certified by the most demanding public and private laboratories, proving its effectiveness and safety.


It is an advanced, scientifically certified, and patented smart technology that uses photocatalysis to emit safe H2O2 molecules. This process surrounds pathogens, viruses and bacteria in the air and on surfaces, inactivating their infectious capacity.

DuctFIT® is an active technology that produces hydrogen peroxide molecules that attack and inactivate pathogens, viruses and bacteria at their source in both air and on surfaces. In this way, every single inch of your air and surfaces has a 99.97% elimination rate.

Since hydrogen peroxide molecules “survive” only 5 minutes, there are no dangerous concentrations, and low levels do not damage materials. In addition, the UV lamp does not harm humans or animals as it is not exposed.

Several other air purification technologies can be found on the market:

UV-C lamps: Ultraviolet light is harmful to health so these should not be operated around people or animals. If installed in air ducts, they do not disinfect surfaces.

Ozone generators: Unlike UV-C lamps they do disinfect surfaces, however Ozone damages materials and has a long lifetime. it can also concentrate and exceed the maximum levels, potentially damaging people’s well-being.

HEPA filter: This does not disinfect surfaces and needs frequent replacement as well as maintenance. Additionally, this is a passive technology since the air must pass through the filters and it is only at that moment that viruses and bacteria are captured, but not eliminated.

NASA developed a technology for the International Space Station, and CleanAir Spaces adapted and then patented it for indoor spaces (offices, hotels, hospitals, homes, schools, etc.) to achieve a virus and bacteria-free environment. 

Yes, absolutely. Prestigious private and public laboratories conducted several studies to certify that ductFIT® does not generate compounds that are harmful to humans or animals.

The maximum concentration of H2O2, the active compound that generates ductFIT®, is below 0.05 ppm, or 95% below the limit set by national and international regulatory bodies.

In addition, our products and manufacturing processes are certified by the following regulatory bodies:

ISO: International Organization for Standardization

CE: Certifying that our product has met EU health, safety, and environmental requirements, ensuring consumer safety

ROHS Restriction of Hazardous Substances: Certifying that all our products meet and exceed the essential safety requirements of the European Directives and EN Technical Standards (European Standards).

ductFIT® eliminates more than 99.9% of Sars-Cov-2 (Covid-19), H1N1 (flu) and the enterovirus. In addition, it actively eliminates bacteria such as E-coli, KPC or Legionella, among many others. Government entities like CSIC (Higher Center for Scientific Research of the Spanish Government) and other national and international microbiology departments have certified these results.
DuctFIT® UV-C lamps have been carefully selected to be ozone-free. Our smart technology results in massive energy savings of up to 60%, reducing negative impact on the environment in multiple ways. As confirmed by several studies, our equipment is not harmful to living creatures.

No, various laboratories have proven that ductFIT® does not oxidize metals or other materials.

Yes, we have solutions for all types of spaces: ductFIT® for ducted areas. ductFIT® Cloud for areas without ducts but with a technical ceiling. ductFIT® Mobile and Ceiling for areas without ducts and technical ceilings. ductFIT® Car for small spaces such as inside vehicles or for personal use. ductFIT® Wall ideal for large spaces without ducts.
Yes, the catalyst and the UV-C lamp of the device should be replaced once a year.
Customers, independent laboratories and public authorities from all over the world have verified the safety and effectiveness of ductFIT®. See the “Certifications” section for more information.

CleanAir Spaces uses a variety of ways to test the functionality of our products. All customers should evaluate their specific application and environmental conditions when making an assessment regarding the technology’s potential benefits.
Our customers should also use reasonable safety precautions to prevent the transmission of pathogens, including SARS-CoV2.

You cannot rely on our products alone to contain it or prevent its spread. It is important to comply with all applicable public health laws and guidelines issued by national, federal, state, and local authorities, including guidance published by the World Health Organisation, European Centre for Disease Prevention Control, Centers for Disease Control and Prevention, including but not limited to social distancing, hand hygiene, cough etiquette, and the use of face masks.
