Can You Wash Pillows? Down, Feather, Synthetic and Memory Foam Rules, Frequency and Drying
Quick answer: yes, most down, feather and synthetic pillows can be machine washed, but solid memory foam and often latex pillows should not. Wash down and feather pillows about every 6 to 12 months, use cool or lukewarm water and mild detergent, and dry them completely. Always follow the care tag first.
This article is part of our bedding guide, where you can compare related options.
Pillows collect sweat, skin oil, dust and dust mites over time, even when you use a pillowcase and protector. Washing refreshes them, but the wrong method can ruin the filling. This guide explains which pillows can go in the washing machine, how to wash and dry each type, how often to wash, when to replace a pillow and how to protect pillows. They disagree on shredded foam and latex, so I note the conflict. This is not medical advice. If allergies or asthma are a concern, ask a doctor.
Which Pillows Can Be Washed?
| Pillow type | Machine wash? | Notes |
|---|---|---|
| Down and feather | Usually yes | Cool water, mild detergent, low-heat dry |
| Synthetic (polyester fiberfill) | Usually yes | Gentle cycle |
| Cotton | Usually yes | Check the tag |
| Solid memory foam | No | Hand wash only |
| Shredded memory foam | Sometimes | Check instructions; often can be washed |
| Latex | Usually no | Sources are inconsistent |
Not to machine wash solid memory foam. The agitation and spin can tear the foam, and a source notes it can lose its shape and hold moisture, which invites mold. Shredded memory foam pillows can often be washed, but it is important to check any instructions provided by the manufacturer.
How Often Should You Wash Pillows?
One source suggests washing your down or feather pillow at least every 6 to 12 months. Another gives the same range, roughly twice a year. Wash sooner if you sweat a lot, have allergies or notice odors or stains. Pillowcases and protectors need washing much more often. See the fitted sheet guide for bedding laundry habits.
How to Wash Down, Feather and Synthetic Pillows
- Check the tag. The care tag overrides general advice.
- Remove the pillowcase and protector.
- Wash two at a time, so the machine stays balanced. Use a front-loading machine or a top-loader without a central agitator, if you can. Some sources recommend avoiding machines with agitators.
- Use mild detergent. Use a small amount.
- Choose a gentle or delicate cycle with cool or lukewarm water. For down, cool water is recommended.
- Run an extra rinse to remove soap.
- Press out water gently. Do not wring.
How to Dry Pillows
Thorough drying matters most. One guide says it can take several hours for a pillow to thoroughly dry if you are air-drying it and at least one hour if you are machine-drying it.
Machine dry on low heat. Add dryer balls or clean tennis balls in a sock to break up clumps in down and feather pillows. Stop and fluff the pillows every 20 to 30 minutes. Check the center. It should feel completely dry, with no damp spots. Air dry flat or on a rack in a well-ventilated place, or in direct sun if the label allows. Never use a pillow that is still damp. Moisture can cause mold and odor.
How to Wash Memory Foam Pillows
Hand wash solid memory foam pillows in lukewarm water with gentle detergent, and air-dry them flat.
- Remove the cover and wash it per its label.
- Fill a tub or sink with lukewarm water and a little gentle detergent.
- Submerge and press the foam gently. Do not twist or wring.
- Rinse by pressing out soapy water until clear.
- Squeeze out water with towels, pressing gently.
- Air dry flat away from direct heat. Foam can take a day or more to dry.
Never put memory foam in the dryer. Vacuum and spot-clean between washes. See the best memory foam mattress guide for foam care.
Spot Cleaning
For small stains, use a damp cloth with mild soap. Let it air dry fully. Baking soda sprinkled and vacuumed off can reduce odors (general advice).
When to Replace a Pillow
Washing does not last forever. Replace a pillow when: It stays flat or lumpy after fluffing. It has permanent stains or odors. It does not bounce back when folded in half (a common home test). It no longer supports your neck. It is several years old. 1 to 2 years for some pillows, and longer for quality ones. The search did not give a definitive number. You have new allergies and the pillow may hold allergens.
Protect Your Pillows
Use a pillow protector under the pillowcase. Zippered, breathable protectors work best. Wash pillowcases weekly or every few days if you sweat. Air pillows in a dry place now and then. Avoid eating or drinking in bed. Use a cooling pillow if you sleep hot. See the best cooling mattress guide.
Decorative and Couch Pillows
Decorative pillow inserts can often be washed per their tags, but covers should come off. See the decorative pillows guide for cover and insert care.
What mistakes should you avoid?
A few common mistakes are worth avoiding: putting solid memory foam in the washer; washing a single pillow in an unbalanced machine; using hot water on down; skipping the extra rinse; using a pillow that is still damp; ignoring the care tag.
