Air Purification Product Testing

The efficacy of your air purification device will be determined by measuring the airborne contamination before and after use.

Our Accreditations

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:

Airborne Contamination

A Microbiological Air Sampler is used to measure the viable particles (particles that consist of, or support, one or more live microorganisms) in the air. Our method is based on BS EN 17141:2020 “Cleanrooms and associated controlled environments — Biocontamination control” and BS EN ISO 14698 “Cleanrooms and associated controlled environments — Biocontamination control — Part 1: General principles and methods”.

For on-site testing, Test Labs can help with creating a sampling plan for your environment and visit the site where testing will be performed. Depending on whether it is fungal or bacterial contaminants, results can be expected within a week and a report draft sent to you the following week.

Particle Count

Test Labs can determine the number of ultrafine particles present in the air using a Particle Counter. Our method is based on ISO 14644-1:2015 “Cleanrooms and associated controlled environments — Part 1: Classification of air cleanliness by particle concentration” and ISO 21501-4:2018 “Determination of particle size distribution — Single particle light interaction methods — Part 4: Light scattering airborne particle counter for clean spaces”.

Volatile Organic Compounds

Volatile Organic Compounds are organic compounds that have high vapour pressure at room temperature and are a type of pollutant that can be found in the air indoors (e.g., formaldehyde). Bad indoor air quality can pose health risks to occupants and therefore it is important that any Air Purification system being used reduces these pollutants and does not release any VOCs in the process.

Determination of the VOCs present can be done by either collecting a sample of the air after using your unit and performing chemical analysis on the sample, or by using sensors to detect specific chemicals that you want to monitor.

Air Circulation

In addition to determining the efficacy of your unit in terms of biocontamination levels, Test Labs will measure the air delivery rate of your unit to determine its air circulation efficiency within the environment.
