Great for allergy symptoms

I have allergies all year and since I started using the Blue Pure air filter I have noticed a huge difference. My sneezing “attacks” have almost completely stopped and I definitely don’t have the allergy symptoms as bad anymore. When I open my windows and shut my Blue Pure off, my allergy symptoms come back.
I would recommend this to a friend!
