Stop bacteria and viruses with air filters
Wherever many people spend long periods of time together, the risk of contracting flu or cold viruses or bacteria increases. When a sick person breathes, talks, coughs or sneezes, thousands of infectious droplets – also called aerosols – spread through the air.
The OFI is not only able to determine the bactericidal and virucidal activity of textiles or non-porous surfaces, but can also test the passage of bacteria and viruses through air filters (air filter testing).
The tests are carried out using the Topas AFC 132 modified filter test rig developed as part of the Aeropore research project. The evaluation is performed both by particle counting to determine the amount of viruses or bacteria retained or passed through the filter in droplet form (0.2-2µm), and by microbiological methods. These are used to detect viruses and bacteria, even if they are in dry form.
The OFI offers
- Validated tests on the retention capacity of bacteria (cocci) on the filter test rig
- Validated tests on the retention capacity of viruses (bacteriophages) on the filter test rig
