Tristan Russell BSc. PhD


Tristan graduated from the University of Leeds with a BSc in Microbiology. During his degree, Tristan completed a one-year internship at a pharmaceutical company where he gained experience of working in an industrial laboratory. Tristan moved to Ireland in 2014 after choosing to study for a PhD at University College Dublin. The PhD research used molecular biology techniques to study infectious disease, specifically host-virus interactions. Tristan recently graduated from his PhD and joined the virology team at airmid healthgroup in the spring of 2019.

Allergen Barrier Test with Airflow (Ref SP304)

To prove the effectiveness of a fabric, zipper or seam as a barrier to the passage of indoor allergen.

Test Description
House Dust with a known concentration of allergen is pulled across the fabric, zipper or seam with the use of controlled air pressure. A filter located downstream collects any allergen that passes through. The amount recovered on the filter is extracted and quantified using an ELISA kit specific for the type of allergen being measured.

Customer Benefit
The data generated by this test allows manufacturers and retailers to directly claim the ability of a fabric, zipper or seam to block a number of allergens. This test is important because there is a tendency to rely on pore size and thread count to demonstrate a fabric’s ability to block allergens. This can be very misleading. Pore size only loosely correlates with allergen filtration efficacy and there are a number of factors that contribute to this. A high thread count fabric may also be poorly constructed, allowing the passage of allergens.

Third Party Validation
On passing this test, the fabric can be labelled as having been tested by airmid in support of any claim relating to the test and data received.

Sample Required
1 square metre of fabric

Turnaround Time
15 working days from receipt of sample
