FAQ

Ask Us Anything

Our air activated warmers all contain a mixture of natural ingredients, like Iron Powder, Super Absorbent Polymer, Water, Vermiculite, Activated Carbon and Salt. The principle of exothermic chemical reaction is the Tri-iron tetraoxide contact with oxygen to release heat from oxidation reaction, Activated Carbon, Sodium Chloride, Water and Super Absorbent Polymer are catalyst to accelerate exothermic chemical reaction of Tri-iron tetraoxide and oxygen, Vermiculite will expands because of heat , and then form a layer for heat preservation to extend the heating time.

The heat patch can stimulate circulation and activate a smoother flow of blood, providing temporary relief of minor muscular and joint aches and pains associated  with overexertion, strains, sprains, and arthritis.

All the inner materials in the product are pure natural and friendly to the environment.

Yes, our products are disposable and cannot be reused. Once the sealed bag is opened, the product will react immediately after contact with the air, releasing heat until the reaction is complete.

Generally, our products have a shelf life of at least 3 years.
