Compare Thermophore's most popular moist heating pads side by side. These models are known for weighted construction, automatic moist heat, and stronger heat than many generic pads. All listed models are HSA/FSA eligible and include a 2-year warranty.
165–170°F
Dramatically hotter than generic pads
Most drugstore pads max out at 120°F. Every Thermophore reaches at least 165°F — the intensity needed for real deep-tissue therapeutic relief.
Auto Moist
Moist heat — no water needed
The moisture-wick fleece cover draws humidity from the air and converts it to therapeutic steam automatically. No wet towels, no spray bottles.
~4 lbs
Weighted — molds to your body
2–3× heavier than generic pads. The weight conforms to body curves, eliminates air gaps, and maintains full surface contact for consistent heat delivery.
