The AtmosRx ceramic filters add an extra step to filtering your mouthpiece when vaping dry herbs or wax. Ordering a 5pack is best because residue will build up over time and they're not easy to clean. Plus people prefer to have a fresh and clean taste.
The Apex Mouthpiece is a multipurpose mouthpiece that fits other portable dry herb vaporizer devices such as the Titan I, Kpen, and Gpro. The mouthpiece comes with a screwable metal filter screen to prevent dry herbs from going through the mouthpiece.
