Keep your Boundless unit fresh with replacement mouthpiece screens. The mouthpiece screen is intended to sit inside the mouthpiece assembly and prevents any dry herb from entering the mouthpiece. It is recommended to keep this screen as clean as possible to enjoy the most out of your Boundless unit.

It is recommended to clean with warm water or isopropyl alcohol.
If using isopropyl alcohol please be sure to rinse with water and dry prior to use.
