"Little Allergies" allergen blocker?

I’ve seen TV ads recently about this product. Its a gel that is rubbed under the child’s nostrils and traps allergens from entering the nasal passage. Sounds like a wonderful product! It uses (apparently) positively charged ionized water so it attracts the negatively charged allergen spores. (not that I really have a clue about those details but sounds good right?)

Anyway, my youngest has pollen allergies so I’m going to try it…what i’m really wondering thoug is whether it will possibly trap flu germs as well? Any docs or bio majors here? What do you think?
