How Often Should You Replace Pillows? (2026) Plus How to Wash Them

A pillow you sleep on every night collects sweat, oils, dead skin and dust mites, and slowly loses the loft that supports your neck. Most pillows need replacing every 1–2 years — here is how to tell, and how to keep them fresh in between.

When to replace your pillow

• Every 1–2 years for microfibre and down-alternative pillows.
• Up to 3 years for good memory foam, if it still springs back.
• Sooner if it is stained, smells even after washing, or triggers allergies.
• Sooner if you wake with neck or shoulder pain that eases as the day goes on.

The 30-second fold test

Fold the pillow in half and let go. A good pillow springs back to its shape almost immediately. If it stays folded or flops back slowly, it has lost its support and it is time to replace it.

How to wash pillows (step-by-step)

1. Check the care label — most microfibre and down-alternative pillows are machine-washable; solid memory foam usually is not (spot-clean only).
2. Wash two at a time to balance the drum, on a gentle warm cycle with a small amount of mild detergent.
3. Run an extra rinse to remove all detergent, which otherwise clumps the fill.
4. Dry on low heat with a couple of clean dryer balls (or tennis balls) to break up clumps and restore loft, or air-dry fully in shade.
5. Make sure the pillow is bone dry before use — any trapped moisture leads to mildew and smell.

Make pillows last longer

• Use a pillow protector under the cover — it takes the sweat and oils, and washes easily.
• Wash pillowcases weekly along with your sheets.
• Air pillows in indirect sun occasionally to freshen them.
• Fluff daily so the fill redistributes and holds loft.
