Key criteria when sourcing an air purifier

Airflow Dynamics

Ensure there is no ‘short circuiting’ between the exhausted air and the air being drawn into the unit. This also ensures maximum air purging in the given area to ensure there are no dead spots. Many air purification units have air intake and exhaust to close to provide good room circulation. Side and bottom air exhaust are not ideal, top air exit and bottom air intake offer the best room purging. It also draws harmful particulate downwards, away from the breathing zone.

UVc lamps for decontamination

The breaking down and deactivation of pathogens with UVc along with the removal of particulate provides optimum air purification. It also ensures no harmful pathogens survive on the filters if the UVc is placed where it is dosing the filters.

Tested and certified H14 HEPA filters

There are many filters on the market that claim ‘HEPA filtration’ but a true HEPA filter will be tested and have a certificate with it. H14 HEPA filters are over 99.99% efficient at below 0.06 microns and should be used in microbiological applications. Some air purification units also have the capacity to test the HEPA filter in situ which offers the ultimate protection.

Correct air volume

It is key that the air volumes the unit is delivering is suitable for the size of the room it is located in. Relating the room size to the air delivery capacity of the unit is critical to getting high levels of air purification.
