HotHands warmers are made of natural materials including iron powder, water, salt, acivated charcoal and wood fiber. Once removed from the specially designed outer packaging the exposure to air activates the ingredients and the warmer begins to build heat. Always allow 10 to 20 minutes for the warmers to reach their optimal temperatures.

Q.  What’s in a pack? What makes it work?
A.  Our HeatMax® family of air activated warmers all contain a mixture of natural ingredients that when exposed to air react together to produce heat. This is accomplished through an extremely fast oxidation (or rusting) process. Ingredients include: iron powder, water, salt, activated charcoal and vermiculite. HeatMax® has perfected the process so that our warmers, depending on the individual product, produce heat anywhere from 100°F to 180°F for duration of 1 to 20+ hours.

Q.  What about the environment?
A.   Another great point about the HeatMax® product line of warmers is that they are completely environmentally safe. Just use and dispose of in your everyday garbage.

Q.  Is every warmer the same?
A. No. HeatMax® has the ability to manufacture air activated warmers in different sizes and with different temperature ranges. Packs are manufactured to fit the needs of our consumers.

Q.  Why can’t the warmers be applied directly to skin?
A. Although all HeatMax® warmers are safe to handle and use, some people with sensitive skin (especially young children, Diabetics and the elderly) may have reduced sensation to heat. Please read all instructions for use with each product and apply them properly.

Q.  Can HeatMax® warmers be taken aboard airplanes?
A. Yes. There is absolutely no problem with taking them aboard or using them during flight. They are completely safe for air travel.

Q.  Are HeatMax® warmers reusable/rechargeable?
A. No. Our warmers are designed for one-time use and then disposed of in regular garbage.
