I think I am allergic to dust. I notice that when I clean our house or vacuum the floor I start to sneeze a lot. My son does that too. I wonder if one of the reasons why I sneeze a lot is the carpet. I vacuum our floor almost everyday but I am not sure how good our vacuum can clean. I guess we need a new vacuum. We need a vacuum that is essential for allergy sufferers and a vacuum that would clean our carpet really well. Allergybuyersclubshopping.com has great vacuums for allergy sufferers. When we are ready to buy a new vacuum, I will check their website again. I like the one that I saw on their website, it is called Miele S7580 Upright Hepa. Check it out, you might like it too.
