The mosquito repellent comes in the form of a mat, similar
to those found in personal insect repellent cartridges hunters often use. This
mat is inserted into the back of the unit where it is heated up and dispersed
into the air. The fan then brings the air through the blades picking up the
repellent and dispersing it in the area you wish to be mosquito free. Should
you need more information on how it works or the ingredients, please reach out
to SUNHEAT International directly for a copy of the safety data sheet.
