Comes with a 5 years warranty, it is capable of providing silent filtration throughout the whole process, a wide coverage area, neat electronic control buttons, convenience features such as internal cord storage system and filter replacement indicator. The only thing that I would dislike is probably the outdated aesthetics look which I guess it shouldn’t be a problem for most people.
