I have the misfortune of suffering each year with allergies and it seems like this year my allergies have lasted weeks longer than usual. I’ve been sneezing and having sinus headaches ever since the temperatures hit 70 degrees. I’ve always been sensitive to tree pollen, but now I’m concerned that there are other things in the air that bother me, too.An air purifier might possibly help with my allergies and also help reduce the sensitivity to the other things that are giving me such grief.
