This is a portable unit on wheels and can be moved anywhere in your home it will stay fill for five to seven years depending how often it is used it comes with extra long tubing and two extra tubing for the nose in case one gets ruined somehow these sell for around 2000-2500. Brand new and this unit has only been used two times. that price is without insurance I'm asking $500.00 OBO since this machine has only ever been used two times
