Common Questions
?Do air purifiers work for hayfever?
Yes. They are extremely effective at trapping pollen, which settles quickly indoors without airflow.
?Should I keep windows open?
No. Open windows let in more pollen than the purifier can remove. Keep the room sealed.
?Does filter grade matter?
H13 is standard, but even H11 (EPA) filters remove pollen effectively as the particles are large.
?Where should I place it?
In the bedroom, near the bed but not blocking airflow, to ensure a clean sleeping environment.
