If we keep our pillows covered with certified allergen-barrier covers, do they still need to be replaced every two years?

Marcia, that's a great question. I think that the replacement will help other things -- like the structural integrity of the pillow. After two years of sleeping on something like a pillow, it may not be offering you the best night's sleep.

The bedroom should be kept allergen and asthma trigger free. It may be difficult, but it is important to try! When we are lying down, our breathing problems often worsen. That is why we should have a clean and safe bedroom. We do need to get a good night of rest!
