I have this allergy pillow sham I bought for my boy. Since my son is basically at the height of allergy season with his reaction to summer humidity, I can really only speak about the integrity of the fabric of this sham. 

This is a white pillow case that works as a dust cover for his pillow. It is soft and smooth and zips shut. I haven’t noticed any holes develop or any issues with it at all. For now, I can’t tell if he’s less prone to sneezing because our allergy season is also environmental. Do I think it work to keep our pillow clean? Yes. Do I think it at the very least, doesn’t attract dust? Yes? 

That’s pretty much all I can share. i don’t think my son is sneezing more this season and he’s currently off meds so that’s the reason I gave 5 stars. We’d really only be able to notice if it didn’t work. I think it’s working fine.
