How Often Should You Wash Pillows?

Wash washable bed pillows about twice a year, clean protectors more often, and always follow the care label for down, feather, memory foam, and latex pillows.

Direct answer

Wash washable bed pillows about twice a year, or every 3 to 6 months if you sweat heavily, have allergies, skip pillow protectors, or notice odor. Wash pillowcases weekly and pillow protectors more often than the pillow insert. Always check the care label first because memory foam, latex, down, feather, and decorative pillows can require different cleaning methods.

washable pillow: about 2x yearly; protectors and pillowcases need more frequent washing

Drying is the risk point

A pillow that is not fully dry can smell musty, clump, or grow mildew inside. Use the care label, low heat when appropriate, repeated drying cycles if needed, and enough time for the center to dry, not just the outside fabric.

2Spot clean or vacuum first if the pillow is not machine washable.
3Use a gentle cycle only when the label allows machine washing.
4Wash two compatible pillows together when possible to balance the machine.

FAQ

Can all pillows go in the washing machine?

No. Many down, feather, polyester, and some latex pillows have specific care rules, while solid memory foam usually should not be machine washed. Check the care label before washing the whole pillow.

How often should pillow protectors be washed?

Wash pillow protectors more often than the pillow insert, often monthly or whenever they are sweaty, stained, or exposed to illness. They are meant to reduce how often the insert needs deep cleaning.

When should I replace a pillow instead of washing it?

Replace a pillow if it stays lumpy, smells musty after cleaning, has persistent stains, no longer supports your head and neck, or the care label says it cannot be safely cleaned.
