Environmental Monitoring
Environmental monitoring (EM) is the ongoing programme that demonstrates your cleanroom continues to meet requirements between classifications. We build and run your EM programme: establishing sampling points and frequency, performing particle counting and microbial sampling, setting alert and action limits, and delivering trendable documentation. All in accordance with EU GMP Annex 1, ISO 14644-2 and EN 17141 – ready for audit.
Particle Counting
Particle counting measures the level of airborne particles in cleanrooms and controlled environments – the foundation for cleanroom classification according to ISO 14644 and for particle monitoring according to EU GMP Annex 1. We carry out air particle measurement on-site with calibrated particle counters and deliver a clear report with results, class and assessment against applicable limits – ready for audit.
Calibration
Correctly calibrated instruments are the foundation for reliable measurement results. We offer professional calibration, adjustment and service of particle counters and air sampling equipment with traceable certificates.
IQ/OQ
We perform IQ/OQ qualification (Installation Qualification and Operational Qualification) for particle counters, air samplers and cleanroom equipment. The documentation ensures that your instruments meet GMP requirements.
Repair & Maintenance
We offer professional repair and preventive maintenance of particle counters, microbiological air samplers and related cleanroom equipment. Fast diagnostics, original parts and documented service to minimise your downtime.

What is air monitoring?
Air monitoring is the systematic measurement of airborne particles and microorganisms in cleanrooms and production environments using calibrated particle counters and microbial samplers. It is required under ISO 14644 and EU GMP Annex 1 to verify that controlled environments meet classification requirements. We perform both routine monitoring and one-off measurements across Scandinavia and Europe.
When do you need air sampling or particle counting?
You need air sampling for cleanroom classification, GMP monitoring, pharmaceutical manufacturing, suspected mould, air quality complaints, occupational health investigations, and after renovation or water damage. Regulatory standards such as EU GMP Annex 1 and ISO 14644 specify when monitoring is mandatory. Contact us for a free assessment of whether your situation requires sampling.
What documentation do you deliver?
You receive a complete report with measurement data, ISO 14644 classification results, assessment against relevant limit values and actionable recommendations. The documentation is formatted for regulatory audits, GMP inspections and internal quality control. All reports follow applicable standards and include traceability to calibrated instruments.

Frequently asked questions
Air monitoring is the systematic measurement of airborne particles and microorganisms in cleanrooms, pharmaceutical facilities and hospitals using calibrated particle counters and microbial samplers. It verifies compliance with ISO 14644 and EU GMP Annex 1 standards. Air sampling specifically involves collecting air samples for laboratory analysis of contaminants such as mould, bacteria and volatile compounds.
We offer cleanroom air monitoring, particle counting, microbiological sampling, cleanroom classification (ISO 14644), indoor air sampling, mould testing, workplace air sampling, calibration and IQ/OQ qualification. All services follow ISO 14644, EU GMP Annex 1 and EN 17141 standards. Contact us for a free assessment tailored to your specific needs.
We work to ISO 14644 for cleanroom classification, EU GMP Annex 1 for pharmaceutical production, EN 17141 for microbiological control, ISO 21501-4 for particle counters, 21 CFR Part 11 for data integrity and ISPE GAMP 5 for qualification. These standards cover the full scope of air monitoring in regulated environments. Our documentation and methods are designed to satisfy audits and inspections against these requirements.
The cost of air sampling depends on the type of measurement, number of sampling points, cleanroom class and scope of laboratory analysis. A typical indoor air sampling starts from a few thousand SEK while comprehensive cleanroom classification projects are quoted individually. Contact us for a free assessment and a tailored quote.
Particle counting delivers results immediately on-site during the measurement session. Microbiological analysis and other laboratory samples typically take one to two weeks to process. Calibration turnaround is normally one to two weeks, with expedited service available for urgent needs.
Yes, we provide complete EU GMP Annex 1 compliance support including particle counting, microbiological sampling and audit-ready documentation. Our services cover all Annex 1 monitoring requirements for Grade A through D cleanrooms. We also offer IQ/OQ qualification and traceable calibration for GMP-regulated instruments.
In Sweden, workplace air quality is primarily governed by the Arbetsmiljölagen (Swedish Work Environment Act) and provisions issued by Arbetsmiljöverket (the Swedish Work Environment Authority), including AFS 2023:1 on workplace design. These regulations place obligations on employers to monitor and maintain safe indoor air quality, covering ventilation, airborne contaminants and exposure limits. Our air sampling and monitoring services help organisations demonstrate compliance with these requirements and identify areas for improvement.
Yes, we provide air sampling and cleanroom validation services across Scandinavia, including Norway and Denmark. Our team operates from Sweden with service coverage throughout the Nordic region. We also welcome enquiries from other European countries. All reports are delivered in English.
