Frequently asked questions

What should I look for in a hay fever air purifier?

Genuine MERV-13 filtration, the right size (clean-air delivery matched to the room), quiet operation under ~35 dB, and affordable standard filters.

Do I need a HEPA purifier for pollen?

Not necessarily — pollen is a large particle captured well by MERV-13. Airflow matched to the room matters as much as the filter grade.

Are ioniser purifiers good for hay fever?

No — mechanical filtration is the evidence-based approach for pollen. Avoid ionisers and ozone generators, which can irritate airways.
