I bought four of them today and I am hoping they help. Have they helped you personally?
PS.
I did not buy allergy pillow covers; just the allergy relief pillows.
I tried the allergy pillows last night.They did not work at all for me personally, I will try the allergy mattress cover and all that stuff though anyways. Thank you everyone!

well i use latex pillows from Bed, Bath and Beyond and they are nice, springy and they don’t give me allergic reactions. (I am allergic to dust mites.) Before I used those pillow covers and they worked pretty good, but since i have discovered the latex like the latex best. So yea it did say allergy relief on them and they are wonderful, i would always be waking up congested and sniffling and now i never do!
so yes they make a difference for me!
