Clean rooms are controlled environments designed to limit the presence of particles and microorganisms. They are essential for industries where air quality, precision, and sterility are critical, such as pharmaceuticals, biotechnology, microelectronics, medical devices, optics, aerospace, and hospital laboratories.

To keep these environments compliant, safe, and efficient, you need to rely on rigorous validation protocols, certified equipment, and specialized methods (including Certifiltre for ventilation and air filtration), in line with current standards and regulatory requirements.

Certification and validation services for your clean rooms

Thanks to an integrated approach to building science, technical expertise in microbiology, regulatory rigor, and an understanding of operational realities, Nvira offers a turnkey solution for the certification of your clean rooms, including:

• Assessment of microbiological and particulate contamination
  (viable microorganisms and non-viable particles)
• Certification of clean rooms according to OPQ 2014.01 / 2014.02 standards
• Support: periodic assessment and proposed solutions to improve air quality and microbiological cleanliness of surfaces
• Validation of “as built,” “at rest,” and “in operation” environments
• Testing in accordance with ISO 14644-1 and ISO 14698 (IEST and CETA standards)
• Verification of high-risk environments (pharmaceutical, research centers, fiber optics)

Rest assured that your clean rooms are compliant and validated, from particle assessment to ventilation optimization.

We verify whether your ducts are clean (dust, biological contaminants, etc.) through observation and samples taken from surfaces. We then establish whether your ventilation ducts need to be cleaned and prioritize which ducts and systems should be targeted first. Our impartial analysis gives you the straight facts.

• Verification and post-cleaning certification
• Testing and analysis in accordance with the NADCA standard
• Sampling cassettes or weighing cassettes in the lab

Our experienced staff can help you determine the source of odors and the origin of occupant symptoms, assess the potential impact on occupants and advise on how to correct the situation. We are also present during and after the work to ensure that the problem is properly solved.

Our experts can conduct analyses on different kinds of odours:

• Mould odour: smells damp, earthy, like a cellar, etc.
• Chemical odour: off-gas, formaldehyde (new smell), smoke, cigarette smell, sewer smell, dead animal smell, etc.

In a disaster, poor diagnosis and unsuitable decontamination techniques for certain situations can leave contaminants in the interior environment of a building.

Our certificates of conformity make it possible to certify that the work has effectively eliminated the identified sources of contamination.

Visual inspection, material moisture measurements, surface sampling and indoor air quality testing are all steps that can provide the level of confidence desired by the occupants of your building.
