“Finally, my cough has gone!”

TERRENCE SCOTT, 76, from Colchester bought a purifier after suffering for months with a cough.

As a former RAF pilot and rugby player, widower Terrence had always thought he was in good shape for his age and was rarely ill.

But last winter, he was struck down with flu, followed by a cough that lasted three month. He wasn't hospitalised, but he really struggled with his breathing.
