Please help MN. Am not in the UK, and am suffering the worst seasonal rhinitis I've had for a long time. Antihistamines and cortisone sprays are not helping. So I want to try an air purifier. The one I'm eyeing comes with either a humidifier or a dehumidifier. WTAF? How can both be on offer? And which do I need for my hayfever ????
Grateful for some learned advice!
