Sleeping too warm is a common reason for a bad night. A charcoal-infused pillow is a memory foam or fiber pillow made with activated charcoal, and it is sold to keep you cooler, drier and fresher at night.
This guide covers what activated charcoal is, what a charcoal pillow can and cannot do, what to look for, and five charcoal pillows to compare.
General information, not medical advice; see a doctor if you have trouble sleeping that lasts or gets worse.
Charcoal pillow basics
- Poison Control describes activated charcoal as a form of carbon that binds other substances onto its surface, and it is used in the gut to bind poisons. That use is medical and unrelated to a pillow.[1]
- A review of sleep and the thermal environment found that heat exposure, with bedding and clothing in use, increases wakefulness and decreases slow wave and REM sleep.[2]
- The NHS names a room that is too hot or cold and an uncomfortable bed among the common causes of insomnia.[3]
- We found no study that tests whether charcoal in a pillow cools you, absorbs moisture or removes toxins. The ventilation and the foam type are what change airflow.
- The EPA says furnishings can release volatile organic compounds, and that levels of many are higher indoors than outdoors.[4]

Charcoal and Activated Charcoal
Activated charcoal and regular charcoal are not the same. Poison Control describes activated charcoal as a special form of carbon that can bind other substances onto its surface, a process called adsorption, and says it is effective in adsorbing many types of poison in the gut so the poison does not enter the body.[1] It also says not to confuse burned toast or barbecue briquettes with activated charcoal, since they do not adsorb.[1]
That is the medical use, and it applies to charcoal that is swallowed in a controlled dose. Poison Control says not to treat a poisoning with activated charcoal at home.[1] The charcoal in a pillow is a different product, put into foam or fabric for odor and freshness, and the pillow does not do the work described above.
Why Invest in a Charcoal Infused Pillow
Most charcoal pillows are memory foam or a similar foam infused with activated charcoal. The product pages here describe the charcoal as being for odor, freshness and moisture management, and say the foam is ventilated for airflow.
Heat is a real problem for sleep. A review of the thermal environment and sleep found that heat exposure increases wakefulness and decreases slow wave and REM sleep, and that this holds in real-life conditions with bedding and clothing.[2] The NHS also names a room that is too hot or cold among the common causes of insomnia.[3] A cooler pillow is a small part of that, and room temperature and bedding do more.
- Are Charcoal Infused Pillows Any Good? – They can be a comfortable memory foam pillow, and the ventilation channels and open foam on these pillows add airflow. We found no study that shows charcoal itself cools, absorbs moisture or filters the air.
- Charcoal Gel Pillows – Some pillows add gel layers or beads to the charcoal foam for extra cooling.
- Bamboo Charcoal Pillows – Bamboo charcoal is activated charcoal made from bamboo. It is an ingredient, not a cooling fabric.
- Is a Charcoal Infused Memory Foam Pillow Safe? – The EPA says furnishings are among the many household products that can release volatile organic compounds.[4] Look for CertiPUR-US certified foam, as on the Cushyz and the Owen Holmes.
- Can You Wash a Charcoal-infused Pillow? – Do not machine wash the foam. Most of these pillows have a zip-off or removable cover that you can wash, and the foam is spot cleaned.
Features of a Good Charcoal Infused Pillow
- Materials – Most charcoal-infused pillows have a memory foam fill, whole or shredded, with a cotton, polyester or knit cover that comes off for washing.
- Design – You can choose standard, contoured and ventilated designs, and an adjustable pillow like the Cushyz lets you change the height.
- Options – These pillows come in Standard, Queen and King sizes, depending on the model.
- Certifications – CertiPUR-US on the foam is a good sign for emissions and content.
- Sleep Position – Firm foam suits back and side sleepers, and a soft pillow suits stomach sleepers.
How We Chose These Pillows

- Fill – Memory foam, shredded memory foam or a charcoal knit shell.
- Ventilation – Cut channels or ventilated foam.
- Cover – Removable and washable or not.
- Certification – CertiPUR-US on the foam.
- Size – Standard, Queen or King.
