How often do you replace pillows? I've read

7. Depending on the type, I wash them and

dry them in the dryer if they are foam types. You can also wash feather pillow this way, but it takes hours for them to dry.
My mom used to wash them in the machine and then lay the feather pillows out in the sun in her yard right on the grass and they stayed there until they dried. If it is a hot sun they may lay there for about 2 days and she would turn them over every once-in-a-while. She may have finished the damp ones in the dryer too. But usually she did not have to do that and the pillows came out clean, and fluffy like new. The foam types can get misshapen after being in the dryer but you can kind of reform them and eventually they will go back to their shape once you have used them.

Hope this helps, Cat
