Machine has ultra low run hours at 605. Hrs. This is a V-pap or BI-pap model and highly sought after. This can have both pressures perscibed, inspiration and expiration, making the experience much more comfortable to use. Doctor can prescribe pressures. Excellent condition. Comes with tank, hose, cord, case & air filters. I had an “Inspire implant” and no longer need Bi-pap. With only 605 hours used on the machine, it’s in superb condition. Brand new prices are $2600. -$2900. Resale values are $1300+. For an almost new machine $950. is an excellent price. If you’re in between insurance coverage this is a great deal.
