Gross! I never even thought of the things that a pillow collects. Sure, washing your sheets, blankets and pillow cases are routine. How about the actual pillow? Honestly, I had never even thought of throwing a pillow in a machine.

My mother would hang our pillows on the line or we would just discard them when it was time for a new one. Most likely a few years after we got them.

According to a new study by Dow Polyurethanes, one-third of your pillow's weight contains dead skin, bugs, dust mites, and their droppings after just two years of use!

In an article from PopSugar, we should be washing our pillow once every 3-6 months!! That's right. As many as four times a year!
