How Often to Replace Your Pillow?

At least every year, according to The Today show expert:

"Reduce allergies: Replace pillows every year

Hair and body oils will have soaked into a pillow's fabric and stuffing after a year of nightly use, making it a breeding ground for odor-causing bacteria and allergy-triggering dust mites. Using protectors can double the life of your pillows."

    I have had my pillows for several years and can't imagine throwing them away. They are washable and the ticking is made from a special allergy-proof fabric so they don't need special covers. I bought them at and they told me they were guaranteed for 5 years. It seems wasteful to me to throw something away that is still good. I thought the first part of being environmentally friendly is "reduce". Sheesh

  2. I work for a company that makes pillows and even I am guilty of 'old' pillows :-) We always tell folks to wash pillows every other month and to repalce most pillows after two years. Always use a pillow protector and considering buying a pillow using tencel fabric which helps wick mositure and also feels great.
