My son suffers from allergies and I was looking for ways to ease his symptoms.  When I found these pillow protectors, I thought they would be worth a try.  I am so happy that I did.  After seeing how well they worked for him, I purchased more to use in my bedroom. One extra benefit that I found was that after putting these on my pillows, I noticed a lot less dust in the room. I am assuming it is because the protectors keep in the particles from the feathers in the pillows.  These are well made and a must have.
