These Teflon earscopes are designed to direct ozone into the ears.
This earscope has two advantages: it's made of ozone-resistant Teflon and comes with removable ear buds. This makes it easy to share the earscope with others and/or replace the ear buds. It comes with two pairs of ear buds.
We recommend using a humidifier to humidify the ozone so it is less drying. Ear insufflations allow for ozone to have closer access to the brain than other applications.
