Suzanna and her brother Matthew soon began working on a better travel-friendly, air-freshening solution. The duo landed on dissolvable tablets as the most effective and discreet way to tackle odors. Pottymints are a convenient add-on. It's easy to have one on-hand just about anywhere, just in case. Drop a tablet into the toilet after flushing to release a clean, fresh aroma that will last up to three more flushes.
