Martin O’Connell, an electrical engineer from a dairy farming family in Brosna, County Kerry, admits that he probably wouldn’t have come up with the idea for his Allergy Nasal Filter if his brother’s dairy herd hadn’t contracted TB in 2013.

He wouldn’t be CEO of his own company now – Nasal Medical – or have won the AIB Start Up Academy Award in 2016 or, most recently, have signed a contract with global pharmaceutical giant Mylan, which will probably see his company’s products on sale all over the world in the future.
