I regularly travel with a CareFusion/PureSom unit, supplementing a ResMed S9 that I keep at home. Although the ResMed is a superior overall CPAP unit, the CareFusion/PureSom is no slouch and has some advantages over its more-expensive competition. The design of this water chamber is one of those advantages. It is simple and effective in design, and is the easiest chamber I've ever seen to clean (and I've seen a lot). The internal baffle used to reduce rainout is well designed, easily removed for cleaning, and robust. The seal on the bottom plate is well made and I've never encountered a leak (unless I did a poor job of reassembly). My only concern is that the bottom metal plate is a bit thin and can be slightly deformed by rough handling. Nothing significant but I'd like a bit thicker bottom. Given the low cost of this chamber in relation to those from other manufacturers, it is a bargain.
