This is the new NUWAVE CPAP Cleaner. With three cleaning chamber options, there is certainly one that meets your needs. If you plan on only using the NUWAVE for traveling and would prefer to pack light, invest in the Travel option, which includes one small bag. While you will need to clean your water chamber and mask separately, the smaller footprint of the bag will save you some space. For home usage, the NUWAVE Plus is recommended, which can clean your water chamber and mask together. For those who are wanting to use the NUWAVE for home and travel usage, the NUWAVE Combo is recommended, which still only includes one NUWAVE CPAP Cleaning Device, but includes both the NUWAVE Travel and NUWAVE Plus bags.
