The Exo Terra Natural Light Ion creates a healthy environment for reptiles and amphibians in the terrarium while reducing odors drastically. The Exo Terra Natural Light Ion is a general light source with built-in negative ion generator. Negative ions eliminate odors and help freshen and purify the air in the terrarium. Mold spores, fungi, dust, and other harmful airborne particles are eliminated and neutralized by clumping together. Negative ions also have been shown to be beneficial for the physiological wellbeing. High levels of negative ions are desirable and they are naturally found in places like along coastlines, in the mountains, in deserts, in forests, near rivers and waterfalls, and many other places with an abundance in reptiles and amphibians.
