How to Wash a Casper Pillow for Lasting Freshness

Washing your Casper pillow doesn’t have to be complicated. With the right steps, you can keep it clean, fresh, and supportive for years. This guide walks you through how to wash a Casper pillow safely—whether it has a removable cover or not—so you can enjoy better sleep without odors, allergens, or buildup.

Key Takeaways

• Check the care label first: Always follow Casper’s official cleaning instructions to avoid damaging the pillow.
• Remove and wash the cover separately: Most Casper pillows have a machine-washable cover that should be cleaned every few weeks.
• Avoid submerging memory foam or hybrid cores: These materials can break down if soaked; spot clean instead.
• Use mild detergent and cold water: Harsh chemicals and hot water can degrade fabric and foam.
• Air dry thoroughly: Never use a dryer on foam pillows—heat ruins their structure.
• Deodorize naturally: Baking soda sprinkled on the pillow absorbs odors without moisture.
• Wash regularly but not excessively: Every 3–6 months is usually enough unless spills or stains occur.

Quick Answers to Common Questions

Can I put my Casper pillow in the washing machine?

Only the removable cover should go in the washing machine. The inner foam or hybrid fill must never be submerged or machine-washed, as it can break down or retain moisture.

How often should I wash my Casper pillow?

Wash the cover every 2–4 weeks. Spot clean the core only when needed, and deodorize monthly with baking soda to maintain freshness between deeper cleans.

What detergent should I use?

Use a mild, fragrance-free detergent. Avoid bleach and fabric softeners, which can damage the fabric and reduce breathability over time.

Can I dry my Casper pillow in the dryer?

Only the cover can go in the dryer—and only on low heat. Never put the foam or hybrid insert in the dryer, as high heat can melt or warp the material.

How do I remove odors from my Casper pillow?

Sprinkle baking soda on the pillow surface, let it sit for 15–30 minutes, then vacuum it off. This absorbs odors naturally without adding moisture.

Why Washing Your Casper Pillow Matters

Your pillow collects sweat, dead skin cells, dust mites, and allergens every night. Over time, this buildup can affect your sleep quality—and even trigger allergies or skin issues. That’s why knowing how to wash a Casper pillow properly isn’t just about cleanliness; it’s about protecting your health and extending the life of a product designed to support better rest.

Casper pillows are known for their innovative materials—like responsive foam, down alternative, or hybrid fills—that provide comfort and alignment. But these materials require special care. Unlike basic cotton pillows, you can’t just toss them in the washer and forget about it. A wrong move could flatten the fill, damage the foam, or trap moisture inside, leading to mold or mildew.

The good news? With a little attention and the right technique, keeping your Casper pillow fresh is simple and effective.

Step 1: Check the Care Label and Pillow Type

Understand What You’re Working With

Before doing anything, flip your pillow over and look for the care tag. Casper designs different pillows with different fills, and each has specific cleaning guidelines. For example:

• Original Casper Pillow: Features a polyester cover and a fiber fill. The cover is machine-washable, but the inner fill should not be submerged.
• Casper Foam Pillow: Contains memory foam. The removable cover can go in the wash, but the foam core must only be spot cleaned.
• Casper Hybrid Pillow: Combines foam and fiber. Again, wash the cover, but never soak the insert.

If you’ve lost the tag, visit Casper’s official website or contact customer support. Never guess—especially with foam-based pillows.

Step 2: Remove and Wash the Pillow Cover

Machine Washing the Outer Layer

Most Casper pillows come with a zippered, removable cover made from breathable, durable fabric. This is the part that takes the brunt of daily use—and it’s fully machine washable.

Here’s how to do it right:

• Unzip and remove the cover completely.
• Wash it in cold water on a gentle cycle.
• Use a mild, fragrance-free detergent to avoid irritating sensitive skin.
• Avoid bleach or fabric softeners—they break down fibers and reduce breathability.
• Tumble dry on low heat or air dry flat to prevent shrinkage.

Washing the cover every 2–4 weeks keeps your sleeping surface hygienic and fresh. Think of it like changing your sheets—but for your pillow.

Step 3: Spot Clean the Pillow Core (If Needed)

Safe Cleaning for Foam and Hybrid Fills

Never put a memory foam or hybrid pillow insert in the washing machine. Water gets trapped inside, and the foam can crumble or lose its shape. Instead, spot clean stains gently.

Here’s a safe method:

• Mix a small amount of mild soap with cold water.
• Dip a clean cloth into the solution, wring it out well—it should be damp, not wet.
• Gently blot the stained area. Don’t rub, as this can push dirt deeper or damage the foam.
• Use a second cloth dampened with plain water to rinse the area.
• Press with a dry towel to absorb excess moisture.

Let the pillow air dry completely in a well-ventilated room—never in direct sunlight or near a heater. This prevents warping and ensures no moisture remains inside.

Step 4: Deodorize Naturally Between Washes

Keep It Fresh Without Water

Between deep cleans, your pillow can still pick up odors. A simple trick? Use baking soda.

Sprinkle a thin layer of baking soda over the surface of the pillow (with the cover off). Let it sit for 15–30 minutes, then vacuum it off with a handheld vacuum or brush. Baking soda neutralizes odors without adding moisture—perfect for foam pillows.

This is especially helpful if you sweat at night or live in a humid climate. Do this once a month to maintain freshness.

Step 5: Dry Thoroughly and Reassemble

Patience Prevents Mold

After any cleaning—whether washing the cover or spot treating the core—make sure everything is 100% dry before putting the pillow back together. Trapped moisture leads to mold, mildew, and unpleasant smells.

Lay the cover flat or hang it to dry. For the pillow insert, place it in a well-avoid area with good airflow. Never use a hairdryer, radiator, or clothes dryer on foam—it can melt or warp the material.

Once dry, zip the cover back on and fluff the pillow by hand to restore its shape.

Bonus Tips for Long-Lasting Freshness

Protect Your Investment

Want to wash your Casper pillow less often? Use a pillow protector underneath your pillowcase. It acts as a barrier against sweat, oils, and allergens—and it’s easy to toss in the wash weekly.

Also, consider your sleep environment. If you’re a hot sleeper or live somewhere humid, your pillow may need more frequent attention. And if you’re traveling, check out our guide on how to travel with a pillow to keep it clean on the go.

Finally, remember that even with perfect care, pillows don’t last forever. Most experts recommend replacing your pillow every 1–2 years—or when it no longer springs back after being folded in half.

Conclusion: Clean Pillow, Better Sleep

Knowing how to wash a Casper pillow the right way makes a real difference in your sleep hygiene and comfort. By washing the cover regularly, spot cleaning the core, and deodorizing with baking soda, you’ll keep your pillow fresh, supportive, and free of allergens.

It only takes a few minutes every few weeks—and your body (and nose) will thank you. Sweet dreams start with a clean pillow.

Frequently Asked Questions

Is it safe to wash a memory foam Casper pillow?

No—you should never submerge a memory foam pillow in water. Only spot clean stains with a damp cloth and mild soap, then air dry completely.

Can I use vinegar to clean my Casper pillow?

It’s not recommended. Vinegar’s acidity can degrade foam over time. Stick to mild soap and water for spot cleaning, and baking soda for odor removal.

What if my Casper pillow doesn’t have a removable cover?

If the cover isn’t removable, spot clean the entire surface carefully with a damp cloth. Avoid soaking, and ensure it dries fully in a ventilated area.

How do I know when to replace my Casper pillow?

If the pillow doesn’t regain its shape after being folded in half, or if you wake up with neck or back pain, it’s likely time for a replacement—usually every 1–2 years.

Should I use a pillow protector with my Casper pillow?

Yes! A pillow protector adds an extra layer of defense against sweat, allergens, and spills, helping your pillow stay cleaner longer.

Can I sun-dry my Casper pillow?

Avoid direct sunlight. UV rays and heat can damage foam and fabric. Instead, dry it in a shaded, well-ventilated indoor space.
