Yes, can you put a pillow in the dryer depends on the pillow type, but most down, feather, polyester, and down-alternative pillows can go in the dryer on low heat or air-dry settings. Memory foam, latex, gel, and some specialty pillows should not go in the dryer because heat and tumbling can damage their shape, support, or inner structure.
Drying a pillow properly matters because damp filling can trap odor, mildew, and allergens. The Asthma and Allergy Foundation of America notes that dust mites thrive at temperatures around 70°F and above, especially when humidity rises above 50%. That is one reason pillows need complete drying, not just surface drying.
You should always check the care label first. The Federal Trade Commission explains that care labels give washing and drying instructions needed for ordinary use, including whether an item can be tumble dried.
In this guide, you’ll learn which pillows can go in the dryer, which ones should never be machine dried, how to dry pillows safely, and how to avoid lumps, odors, shrinkage, and heat damage.
Can You Put a Pillow in the Dryer? Why It Matters
Putting a pillow in the dryer sounds simple, but pillows hold moisture deep inside the filling. A pillow can feel dry outside while the center stays damp. That trapped moisture can lead to musty smells, clumping, and poor support.
Drying also affects comfort. Too much heat can shrink covers, melt synthetic fibers, or make foam brittle. Too little drying time can leave the pillow heavy and flat. The right method depends on fill type, cover fabric, and care label instructions.
Common problems readers experience include:
- Pillow comes out lumpy or uneven
- Pillow smells musty after washing
- Down or feather filling clumps together
- Memory foam becomes cracked or misshapen
- Pillow cover shrinks after high heat
- Pillow feels dry outside but damp inside
The National Institute of Environmental Health Sciences recommends keeping indoor humidity at or below 50% and washing bedding in hot water, 130°F to 140°F (54°C to 60°C), where safe, to help kill dust mites. For pillows, the key is using the warmest safe method without damaging the material.

Best Ways to Dry a Pillow Safely
1. Check the Care Label First
Start with the care label before using the dryer. Look for drying symbols such as a square with a circle for tumble drying, one dot for low heat, two dots for medium heat, and a crossed-out tumble dry symbol for no dryer.
Benefits: You avoid heat damage and follow the manufacturer’s instructions.
Drawbacks: Some older pillows may have faded or missing labels.
2. Use Low Heat for Washable Pillows
Most washable pillows dry best on low heat. Low heat protects fabric covers and reduces the risk of melted polyester fibers or damaged seams.
High heat may seem faster, but it can make the pillow stiff, flat, or misshapen. If the pillow contains down or feather fill, low heat also gives moisture more time to escape.
3. Add Dryer Balls or Clean Tennis Balls
Dryer balls help separate the filling as the pillow tumbles. They reduce clumping and help air move through the pillow.
Use two or three wool dryer balls or clean tennis balls inside white socks. This protects the pillow cover and softens the impact.
Benefits: Better fluff, faster drying, fewer lumps.
Drawbacks: Dryer balls can be noisy.
4. Dry Two Pillows at a Time
Drying two pillows together helps balance the dryer drum. This is especially useful in top-load washing routines where pillows may already hold uneven moisture.
Do not overload the dryer. Pillows need room to tumble, expand, and release trapped water.
5. Pause and Fluff Every 30 Minutes
Stop the dryer every 30 minutes and fluff each pillow by hand. Press the corners, shake the pillow, and break up dense areas.
This step helps prevent wet pockets inside the fill. It also keeps down, feather, and polyester pillows from forming hard clumps.
6. Use Air Fluff for Delicate Fill
Air fluff uses tumbling without heat. It works well for pillows that can tumble but should avoid heat.
This method takes longer, but it reduces shrinkage and heat stress. It is useful for delicate covers, older pillows, and some down pillows.
7. Finish With Air Drying If Needed
Even after a dryer cycle, place the pillow in a well-ventilated area for extra drying. Stand it upright or lay it flat on a clean drying rack.
Do not place a damp pillow back inside a pillowcase. Moisture trapped under fabric can create odor quickly.
8. Replace Pillows That Stay Lumpy or Smelly
If a pillow remains lumpy, flat, or musty after washing and drying, it may be time to replace it. Cleaning cannot restore broken foam, worn-out polyester, or damaged feather fill.
A pillow should spring back and support your head evenly. If it folds in half and stays folded, it has likely lost its structure.
Step-by-Step Guide
- Read the care label. Look for tumble dry, low heat, air dry, or do-not-dry symbols. If the label says “dry clean only” or “do not tumble dry,” do not use the dryer.
- Remove pillowcases and protectors. Dry the pillow itself separately from covers. This improves airflow and prevents layers from trapping moisture.
- Press out excess water. Do not twist the pillow. Press it gently between towels to remove extra moisture before drying.
- Place pillows evenly in the dryer. Add one or two pillows, depending on dryer size. Make sure they have enough room to move.
- Choose the right setting. Use low heat for down, feather, polyester, and down-alternative pillows. Use air fluff when the label allows tumbling but warns against heat.
- Add dryer balls. Use wool dryer balls or clean tennis balls inside socks. They help restore loft and reduce clumps.
- Check every 30 minutes. Remove the pillow, fluff it by hand, and feel for damp spots. Pay attention to the center and corners.
- Confirm it is fully dry. Smell the pillow and press firmly into the middle. If it feels cool, heavy, or damp, continue drying.
- Air it before use. Let the pillow rest in a dry room for at least one hour before putting on a pillowcase.
Pro tip: Weigh the pillow before washing if you want a precise dryness check. When it returns close to its original dry weight, most trapped moisture has been removed.

Expert Tips and Common Mistakes
Expert Tips
- Use low heat rather than high heat for most washable pillows.
- Always dry pillows completely before putting them back on the bed.
- Use dryer balls to restore loft and reduce clumping.
- Wash and dry two pillows together for better balance.
- Choose breathable pillow protectors to reduce sweat and oil buildup.
- Replace pillows that stay flat, sour-smelling, or uneven after cleaning.
Common Mistakes to Avoid
Mistake 1: Drying memory foam in the dryer.
Memory foam can break apart, crack, or lose its contour when exposed to heat and tumbling. Spot-clean it instead, then air dry it flat in a ventilated space.
Mistake 2: Using high heat to save time.
High heat can shrink covers, damage seams, and weaken synthetic fibers. A longer low-heat cycle is safer for most washable pillows.
Mistake 3: Assuming the outside means the inside is dry.
Pillows dry from the outside first. The center can stay damp for hours, especially in down, feather, and thick polyester pillows.
Mistake 4: Putting a damp pillowcase on too soon.
A pillowcase traps leftover moisture against the pillow. Let the pillow cool and air out before dressing the bed.
Frequently Asked Questions
Can you put a pillow in the dryer after washing it?
Yes, you can put many washable pillows in the dryer after washing, especially down, feather, polyester, and down-alternative pillows. Always use the care label first, then choose low heat or air fluff.
Can you put a memory foam pillow in the dryer?
No, memory foam pillows should not go in the dryer. Heat and tumbling can damage the foam, so spot-clean them and let them air dry flat.
How long does it take to dry a pillow in the dryer?
Most washable pillows take 1 to 3 hours on low heat. Thick down or feather pillows may take longer because moisture hides deep inside the fill.
What dryer setting is best for pillows?
Low heat is best for most dryer-safe pillows. Air fluff is safer for delicate pillows that can tumble but should not be exposed to heat.
Can pillows catch fire in the dryer?
Pillows can overheat if dried on the wrong setting, packed too tightly, or left in a dryer with poor airflow. Use the correct setting, clean the lint trap, and check the pillow often.
How do you keep pillows from getting lumpy in the dryer?
Use dryer balls or clean tennis balls inside socks. Pause the dryer every 30 minutes to shake and fluff the pillow by hand.
Can you put feather pillows in the dryer?
Yes, many feather pillows can go in the dryer on low heat if the care label allows it. Dry them fully, because damp feathers can smell bad and clump together.
Conclusion
So, can you put a pillow in the dryer? Yes, if the pillow is made from down, feather, polyester, or down-alternative fill and the care label allows tumble drying. No, if it is memory foam, latex, buckwheat, or a specialty pillow that warns against heat or tumbling.
The safest method is simple. Check the label, use low heat, add dryer balls, pause to fluff, and keep drying until the center is fully dry. If temperature matters, remember that bedding allergy guidance often references 130°F to 140°F (54°C to 60°C), but you should only use heat levels your pillow can safely handle.

Expert Opinion
In my experience, most pillow problems come from incomplete drying, not washing. A pillow can look clean and still hold moisture in the center. That moisture is what causes musty odors, clumping, and poor sleep comfort.
I always recommend starting with the care label because it gives the safest product-specific guidance. The FTC’s care labeling guidance supports this approach, and allergy organizations such as AAFA and NIEHS show why moisture control and bedding hygiene matter in real homes.
For most households, low heat, dryer balls, and patience solve the issue. For foam and latex pillows, skip the dryer completely and air dry them with good airflow.
