Quick Take: Looking for the best support? We recommend the Saatva Pillow for consistent comfort and adjustable loft.
Pillows absorb sweat, skin cells, and oils every night. Over time, this buildup can cause odors, allergies, and even acne. Washing your pillow regularly is essential for hygiene and longevity, but doing it wrong can ruin the fill or warp the shape.
This guide explains how to wash every major pillow type safely, how often to clean them, and how to dry them without clumping or mildew.
How Often Should You Wash Your Pillow?
- Down and down alternative: Every 3-6 months
- Memory foam: Never machine-wash the core; spot-clean only and wash the cover monthly
- Latex: Never machine-wash; spot-clean and air-dry
- Shredded foam / adjustable: Wash the cover every 2-4 weeks; replace or refresh the fill annually
How to Wash Down and Down-Alternative Pillows
- Remove the pillowcase and protector.
- Load two pillows into a front-loading washer to balance the drum.
- Use a gentle cycle with warm water and a small amount of mild detergent.
- Add an extra rinse cycle to remove all soap residue.
- Dry on low heat with wool dryer balls to fluff the fill. This may take 2-3 cycles.
- Ensure the pillow is completely dry before use to prevent mildew.
How to Wash Memory Foam Pillows
Do not put solid memory foam in the washing machine. The agitation will break the foam cells and create permanent sagging. Instead:
- Vacuum the surface with an upholstery attachment.
- Mix a solution of lukewarm water and mild detergent.
- Dampen a clean cloth and gently blot stains. Do not soak the foam.
- Sprinkle baking soda over the surface, let sit for 1 hour, then vacuum again.
- Air-dry completely in a well-ventilated area, away from direct sunlight.

How to Wash Latex Pillows
Latex is even more sensitive to moisture and heat than memory foam. Follow the same spot-clean method as memory foam, but avoid all detergents containing enzymes or solvents, as these can degrade the latex. Always air-dry; never use a dryer.
Drying Tips for All Pillow Types
- Use wool dryer balls or clean tennis balls to break up clumps
- Dry on low or no heat to prevent shrinkage and fiber damage
- Hang pillows vertically by a corner to allow internal airflow
- Check for damp spots by pressing firmly into the center before storing
Final Recommendation: Still unsure? The Saatva Pillow remains our favorite for side, back, and combination sleepers who want hotel-quality sleep at home.
Regular washing extends pillow life and protects your skin and respiratory health. If your pillow still smells after washing, the inner fill may be permanently saturated and it is time to replace it.
Frequently Asked Questions
How often should I replace my pillow?
Every 1-2 years for synthetic fill, 2-3 years for latex or high-density memory foam. Flattening, odors, or morning neck pain are signs it is time.
Is a higher pillow better for side sleepers?
Side sleepers need enough loft to fill the gap between shoulder and ear. Too high causes neck tilt; too low causes shoulder compression.
Can the wrong pillow cause headaches?
Yes. Poor spinal alignment from incorrect loft or firmness can tension neck muscles and trigger tension headaches.

Why This Matters for Your Sleep
Choosing the right how to wash a pillow directly impacts sleep quality, neck alignment, and morning stiffness. Most people underestimate how much their pillow contributes to restful sleep until they experience the difference a proper match makes. The wrong choice can lead to chronic neck pain, headaches, and disrupted sleep cycles.
Research consistently shows that sleep position, body type, and existing conditions like sleep apnea or acid reflux should all factor into your decision. A one-size-fits-all approach rarely works when it comes to sleep comfort.
Common Mistakes to Avoid
One of the biggest errors shoppers make is prioritizing price over fit. A cheap pillow that forces your neck into an unnatural angle costs far more in chiropractic bills than a quality option upfront. Another frequent mistake is ignoring fill type, memory foam, latex, down, and buckwheat each behave differently and suit different sleeper profiles.
We also see people keeping pillows far too long. If yours has lost its loft, developed lumps, or no longer springs back when folded, it is time to replace it regardless of what the calendar says.
Expert Tips for Getting the Most Value
Start by identifying your primary sleep position. Side sleepers generally need higher loft and firmer support. Back sleepers do well with medium loft that cradles the cervical curve. Stomach sleepers should look for thin, soft options to prevent neck hyperextension.
If you share a bed with a partner who has different needs, consider adjustable fill pillows or buying separate models. Your sleep quality is too important to compromise on a middle-ground option that satisfies nobody.
When to Upgrade
Replace your pillow every 18 to 36 months depending on material quality and usage. Memory foam and latex typically last longer than down or polyester fills. Signs you need an upgrade include persistent neck pain, visible staining, odor that does not wash out, or a pillow that stays folded when you bend it in half.
