I purchased a pureAir Solo after suffering for months with hayfever for the first time in my life.
I especially like it at night, keeping it within the 3 foot radius.
Having a cord to use during the day is also very convenient.
Love the fresher air it produces especially with pets near my bed.
Has helped tremendously with hayfever symptoms and headaches.
Amazing little, convenient, light-weight device!
Glad I purchased!
