PARI Vortex - Non Electrostatic Valved Holding Chamber eliminates static charge to prevent medication from adhering to the inside of the chamber. The lightweight metal material allows for a more consistent and accurate dosage of medication compared to plastic MDI spacers and chambers. Its easy-to-use design makes it ideal for patients of all ages, from children to adults. The new mouthpiece cap minimizes backflow and prevents debris from entering the inhaler chamber. The Pari Vortex is dishwasher safe and does not contain BPA or latex.
