I got this  Insight™ HEPA Air Purifier  because I have allergies to animals and pollen.  My family has a knack for finding strays, so my house is full of animals! I like to run this in the morning and in the evening and if I am having issues with my allergies, I run it more often.  It really blows a lot of air out.  My one year old granddaughter likes to stand by it and blow her hair straight up.  I'm glad it's filtered air blowing in her face!
