How Long to Put Pillows in Dryer to Kill Dust Mites: A Complete Guide

Dust mites are tiny creatures, but their presence in our pillows can cause serious issues like allergies, asthma flare-ups, and even sleep disturbances.

Fortunately, the solution might be easier than you think. Using your dryer properly can eliminate a significant amount of dust mites hiding inside your bedding.

In this guide, you’ll learn exactly how long to put pillows in dryer to kill dust mites and the best practices to keep your sleep environment fresh and healthy.

Will the Dryer Kill Dust Mites in Pillows?

Yes, heat from the dryer can kill dust mites effectively—as long as you use the right settings.

How It Works:

• Dust mites cannot survive sustained temperatures above 130°F (54°C).

• Most modern dryers easily reach temperatures high enough to eliminate them.

• A full drying cycle also helps evaporate moisture that dust mites thrive on.

However, it’s important to understand that drying alone might not remove all mite allergens, like their droppings, which can still trigger allergic reactions. That’s why washing followed by drying is considered the gold standard.

After struggling with sneezing fits during the spring allergy season, I started drying our bed pillows every month along with our protective covers. Finishing them off on our Puffy Lux Mattress, known for its hypoallergenic design, really helped cut down on nighttime sniffles for the whole family.

How Long Do You Put Pillows in Dryer to Kill Dust Mites

Step-by-Step Dryer Instructions:

1. Wash pillows first (if possible) with hot water to remove allergens.

2. Place no more than two pillows in the dryer at once.

3. Add dryer balls or clean tennis balls to help them fluff and move evenly.

4. Select a high heat setting (unless otherwise recommended for your pillow type).

5. Dry for at least 30 minutes; aim for 40–50 minutes to ensure full exposure.

6. Fluff pillows mid-cycle to prevent clumping.

7. Ensure they are completely dry all the way through.

We started doing this quarterly, especially for the kids’ pillows, since little ones often struggle more with dust sensitivity. Pairing clean, dry pillows with our Puffy Cloud Mattress—which naturally resists dust mite buildup—has made a huge difference in our sleep quality.

How Often Should You Put Pillows in the Dryer to Kill Dust Mites?

• Every 1–2 months for everyday-use pillows.

• After any illness, to freshen and sanitize.

• During peak allergy seasons (spring and fall) for extra protection.

Additional Methods to Kill Dust Mites in Pillows

Besides the dryer, here are other useful tactics:

Hot Water Washing:

• Wash pillows at 130°F (54°C) or higher.

• Use a gentle, fragrance-free detergent.

• Always follow pillow care labels.

Steam Cleaning:

• Handheld garment steamers can sanitize pillow surfaces.

• Useful for delicate fabrics or foam inserts.

Freezing:

• Seal pillows in a large bag.

• Freeze for at least 24 hours.

• Kills mites but does not remove allergens—wash afterward.

Best Practices for Dust Mite Prevention

• Use dust mite-proof covers on pillows and mattresses.

• Wash all bedding weekly in hot water.

• Vacuum the mattress and bedroom frequently.

• Control humidity (keep it below 50%) to prevent mite growth.

• Replace pillows every 1–2 years depending on material.

Can You Use the Dryer Alone Without Washing?

Yes, but it’s most effective when paired with washing. If you’re short on time or your pillows aren’t washable, a high-heat dryer cycle can still significantly reduce live mites, even if it doesn’t eliminate their allergens entirely.

Tips for Drying Different Types of Pillows

Synthetic/Down-Alt Pillows:

• Safe for high heat.

• Fluff regularly during drying.

Feather/Down Pillows:

• Use medium heat.

• Allow extra drying time.

Memory Foam Pillows:

• Never use heat.

• Spot clean and air dry only.

• Use natural sunlight or UV lamps to freshen.
