How Often Should I Change My Pillows?
-
Replace Yearly
-
Over time, your pillow will gather hair and body oils as well as dead skin cells. This provides a favorable breeding ground for odor-causing bacteria and dust mites that can aggravate allergies. For this reason, it is suggested that bed pillows be replaced every year. The pillow may also become misshapen, possibly causing you some pain after sleeping on it.
Clean and Protect
-
Those who do not suffer from severe allergies may be able to go a bit longer with the same pillow. It is also an option to regularly wash your bed pillows or to put a protective cover over them to extend their life. Some pillows are marketed as anti-allergy and dust mite resistant, and these pillows might last longer.

Bottom Line
-
If you suffer from allergies, regularly replacing your pillow can help alleviate your allergy symptoms. But, if you are not bothered by your bed pillow, you could stretch the use into two years or even more, with the proper care and maintenance, as long as it still provides you a comfortable sleep.
