The purpose of Air Filtration Units is to improve air quality by removing pollutants and harmful microorganisms. Test Labs can test the efficacy of your Air Filtration Unit using a Microbiological Air Sampler by measuring the reduction of bacterial and/or fungal colonies after running the units for the required time period. The quality of air can also be measured using a Particle Counter, which monitors the dust and particle levels but can also be used to measure the filter efficiency in Heating Ventilation and Air Conditioning (HVAC) systems.
Our in-house methods of testing can provide reliable data and are as follows:
Frequently Asked Questions
What is Air‑Purification Product Testing?
Air‑Purification Product Testing evaluates how effectively an air purification system improves indoor air quality by reducing airborne microorganisms, particles, and chemical contaminants. Testing focuses on microbiological efficacy, particle removal, air circulation performance, and, where required, chemical emissions.
Which types of air purification systems can be tested?
We test a wide range of air purification technologies, including standalone air filtration units, room‑based purification systems, and systems integrated into controlled environments. Testing can be tailored for products intended for healthcare, laboratory, industrial, or indoor occupied spaces, ensuring results are relevant to real‑world use conditions.
How is airborne microbiological efficacy assessed?
Airborne microbiological efficacy is assessed using a microbiological air sampler to measure viable airborne particles before and after operation of the air purification system. This approach is based on recognised cleanroom and biocontamination control standards and allows manufacturers to demonstrate reductions in bacterial and/or fungal contamination under defined test conditions.
What is particle count testing and why is it important?
Particle count testing measures the concentration and size distribution of airborne particles using a calibrated particle counter. This helps assess filtration efficiency, air cleanliness performance, and suitability for controlled or healthcare environments. Particle testing is particularly important for products claiming improved air quality or compatibility with cleanroom or clinical settings.
Can Air‑Purification Product Testing assess chemical emissions or VOCs?
Yes. Testing can include evaluation of volatile organic compounds (VOCs) to determine whether the air purification system reduces chemical pollutants or introduces new emissions during operation. VOC assessment can be performed using air sampling and chemical analysis or targeted sensors, depending on the product design and regulatory requirements.
