What to look for
- Match CADR or recommended room size to the room you will use it in.
- Check annual replacement-filter costs.
- Night mode and low noise matter in bedrooms.
Buying in the UK
Hay fever season in the UK peaks from May to July; a purifier in the bedroom with windows closed can noticeably reduce symptoms.
Frequently asked questions
Do air purifiers help with hay fever?
A true HEPA purifier removes pollen from the air in the room it runs in, which helps many people – especially in bedrooms.
How much does it cost to run?
Most use 10–50 W, so running all day costs only a few pence; filters are the main running cost.
