The best thing about Laveo™ by Dry Flush! Over two years in development, Laveo™ by Dry Flush’s proprietary barrier material completely isolates waste and odor. Once the toilet is flushed you will never see it again. Furthermore, when the unit is emptied, it’s really empty. There is nothing to create a cumulative or lingering “dirty toilet” odor. All surfaces that come in contact with waste are discarded in the double-layered barrier bag.
