Best Air Purifiers for Allergies
If pollen, dust or pets set off sneezing, a runny nose or itchy eyes, an air purifier can reduce the airborne triggers floating around your flat. A True HEPA filter captures the fine particles behind most indoor allergies — pollen, dust-mite debris, pet dander and mould spores.
A purifier is a practical help, not a medical treatment. Used alongside good cleaning and any advice from your GP or pharmacist, it can make a stuffy flat noticeably easier to live in during hay-fever season or if you share your home with pets.
QUICK ANSWER
For allergies, choose a True HEPA purifier — HEPA captures pollen, dust-mite debris, pet dander and mould spores. Size it to your room, run it continuously, and add activated carbon if odours or fumes bother you. An air purifier eases airborne triggers; it is not a medical treatment.
