My 5 year old son, Jaden had asthma, "adhd", frequent respiratory infections, and insomnia all of his life. I finally took him for an allergy test. I discovered that he was allergic to tons of things, including CATS AND DOGS> We put him on Claritin, Singular, and Qvar. I bought these special allergy covers to go on all of his bedding. I removed his curtains, teddy bears, and all other unnecessary stuff that would hold allergens in his room. I bought a vacuum cleaner with a hepa filter. I also bought a hepa filter for his room. It was expensive, about $250. I scrubbed the whole house to get rid of all dust, cat dander, etc... I now dust EVERYTHING often. It has been two months and my son's asthma, sleeping troubles, and hyperactivity is completely gone. The hepa filters are the biggest part. If you need anymore info, email me at [email protected].
