Purificateurs d'air

Air purifiers to help with pollen allergy

Does anyone have experience with air purifiers that capture pollen particles? Anyone tested? Any recommendations, your opinions, knowledge to share? Would Sharp with plasmacluster help? Any other better devices?
Thank you in advance! Have a 10m old baby that is allergic to pollen :(
@joanna_ksiazek, so far i know are the Purifiers generally good for that Problem. But what I know are goods with a HEPA Filter really good for that. ( I do have the same Problem with Pollen). At the moment i have ordered this Item (Xiaomi Purifier 2H ) and hope it can help your baby too.
