Cover for Thermophore
Excellent service, very well made and stitched. Excellent quality. Love it. I highly recommend this product to everyone. Thank you.
Our Take: The Moist-Sure Fleece Cover is the standard replacement cover that comes with every Thermophore heating pad. The cotton/fleece blend absorbs humidity from the air between sessions, and when the pad heats up, it releases that moisture as therapeutic steam — no water needed. Over time, the fleece wears thin, shrinks from washing, or simply loses its ability to absorb moisture effectively. When that happens, your Thermophore produces dry heat instead of moist heat. A $14.99 replacement cover can restore the moist heat function instantly. Available in all 4 Thermophore sizes so you can match your exact pad. Keep a spare on hand so you can wash one while using the other. If you live in a dry climate (Arizona, Nevada, Utah, New Mexico) or use heavy A/C, consider the Moisture-Plus Cover instead — it adds a pocket with a washcloth for supplemental moisture in low-humidity environments.
Why Replace Your Cover
- The fleece absorbs humidity from the air and releases it as steam when heated. Without a properly functioning cover, your Thermophore only produces dry heat. A new cover can instantly restore the moist heat your pad was designed to deliver.
- After years of daily use, the fleece fibers wear thin and lose their ability to absorb moisture effectively. If your Thermophore heats up fine but no longer produces the steam it used to, the cover is likely the issue.
- Machine washing or hot water can cause covers to shrink, leaving the pad partially exposed. A cover that doesn't fully wrap the pad can't produce even moist heat. Hand wash in tepid water with mild soap to prevent shrinkage.
- The cover needs time to dry and reabsorb humidity from the air after washing. Having two covers means you always have a fresh, moisture-ready cover on hand for your next session.
- Model 161 for Large 14" × 27" pads. Model 162 for Medium 14" × 14" pads. Model 164 for Petite 4" × 17" pads. Model F01358 for Extra-Large 18" × 36" pads. All $14.99.
- Same cotton/fleece blend used in Thermophore's original covers. Specifically engineered to absorb atmospheric moisture and produce moist heat. Well made and stitched — customers praise the quality.
- A new cover at $14.99 can restore years of moist heat therapy to a Thermophore pad that still works perfectly. Much more economical than replacing the entire unit.
- If multiple family members share a Thermophore, each person can have their own cover for hygiene. Extra covers also make great add-on purchases when buying a pad as a gift.

Frequently Asked Questions
What sizes does the Moist-Sure Fleece Cover come in?
The Moist-Sure Fleece Cover is available in four sizes. Model 161 fits 14 by 27 inch large pads. Model 162 fits 14 by 14 inch medium pads. Model 164 fits 4 by 17 inch petite pads. Model F01358 fits 18 by 36 inch extra-large pads. All sizes are $14.99.
Why does the cover matter for moist heat?
The cover is one of the key components that allows the Thermophore to produce moist heat without adding water. The cotton and fleece blend absorbs moisture from the humidity in the surrounding air. When the pad heats up, it activates that moisture into therapeutic steam that penetrates deeper into muscles and joints than dry heat alone. Without a properly functioning cover, your Thermophore will only produce dry heat.
When should I replace my Thermophore cover?
Replace the cover when it no longer produces adequate moist heat, when the fleece has worn thin, when it has shrunk from washing, or when it no longer fits the pad snugly. A well-maintained cover can last years, but the fleece does wear over time and loses its ability to absorb moisture from the air effectively.
How do I care for the Moist-Sure Fleece Cover?
Hand wash the cover in tepid water with mild soap and drip dry. Do not machine wash or machine dry, as this can cause shrinkage. Make sure the cover is fully dry and has had time to absorb moisture from the air before re-using. Do not use fabric softener as it coats the fibers and reduces moisture absorption.
What is the difference between the Moist-Sure Fleece Cover and the Moisture-Plus Cover?
Both produce automatic moist heat from ambient humidity. The Moisture-Plus Cover adds a protective pocket with an included washcloth that you can dampen and insert for supplemental moisture in dry climates. The standard Moist-Sure Fleece Cover does not have this pocket and relies entirely on ambient humidity. If you live in a humid climate, the standard cover works perfectly. If you live in a dry climate like Arizona, Nevada, Utah, or New Mexico, consider the Moisture-Plus Cover instead.
Will a new cover restore moist heat to my old Thermophore?
If your Thermophore still heats up properly but no longer produces moist heat, a new cover may restore the moist heat function. The cover is the component that absorbs humidity and produces steam. However, if the pad itself has stopped heating or heats unevenly, the issue is with the heating element and a new cover will not fix that. Contact Thermophore warranty support at 1-800-253-0854 for assistance.
Is it good to have a spare cover?
Yes. Having a spare cover means you can wash one while using the other, so you always have a fresh cover ready for your next session. It also means you always have a backup if your primary cover wears out. Many households with multiple Thermophore users keep extra covers on hand.
