I have had to live with allergies all my life. I had to go miles out of town to an allergy specialist to have test done on me to see what type of allergies I have. The results showed that I have allergies to foods, pollen and pets. I have learned to adjust my life about the foods and what not to eat. Unfortunately, the pollen in the Spring and Fall season is bad as well as to my pets. I love my 5 cats, however several shed hair. I have trouble with my sinuses even though I take allergy medication. I have been thinking on purchasing an IQAir purifier so I can have an allergen free home.
