Indoor Air Purification

Due to the global crisis that Covid-19 has generated, the World Health Organization (WHO) advised several measures, such as covering your mouth with a tissue when coughing or wiping your hands assiduously and thoroughly, however, due to its easy transmission, it is necessary for companies to implement preventive measures to reduce the risk of contagion.

Our advanced solutions

SUEZ offers advanced solutions for the purification of polluted air inside premises and offices. Clean air helps prevent the spread of Covid-19 in workspaces, but also reduces the possibility of getting sick by filtering outside pollution and getting us to breathe fewer allergens, microorganisms and pollutants.


SUEZ carries out indoor air treatment projects incorporating the most appropriate technologies to guarantee maximum efficiency depending on the flow rates to be treated and the characteristics of each installation. Purification technologies are contemplated using systems with different filtering stages: HEPA filters, photocatalytic disinfection systems or adsorbent beds.

SIAV® ventilation equipment

Sistemas Integrales de Ahorro de Ventilación (SIAV®), in English Entire Ventilation Saving Systems, ventilation and purification units formed by four filtration stages.


  • Filter F9 Epm2.5> 90%
  • Photocatalysis with ceramic activated carbon monolith impregnated with TiO2
  • UVGI Germicidal Ultraviolet Light Irradiation
  • HEPA filter 99.95%


SIAV® systems reduce ventilation costs by optimizing the supply of primary air and the internal thermal load. They improve indoor air quality by filtering airborne pollutants in the places where they act, creating an overpressure to ensure that polluted air is not introduced into adjacent areas. They are autonomous equipment, which are installed in false ceilings or cabinets specifically designed for areas with high occupational density.

These units are especially useful in buildings in exploitation or in projects, specifically for the areas indicated below:

  • Areas with a higher density of people
  • Meeting rooms
  • Dining rooms / vending
  • Common areas (elevator landings, etc.)

IQAIR Portable Equipment

The IQAir range reliably and efficiently protects against the harshest indoor pollutants. These portable equipment are ideal for small premises, offices and meeting rooms as they protect from the following agents:

  • Pollen, spores, mites, and other allergens
  • Microorganisms such as viruses, bacteria, and fungal spores
  • Pet allergens
  • Tobacco smoke
  • Volatile organic compounds emitted by vehicles
  • Toxic fog and ozone
  • Cleaning products, sprays and solvents
  • Paints, varnishes and adhesives
