The AirSep Focus is a great little machine, but why choose the oxygen specialists at Vitality Medical? Well, let us tell you:

  2. Buy Back Program- Upgrading from another machine? Sell your old concentrator back to us. Call for details.
  3. Loaner Program - If your concentrator needs a warranty service we will send you a comparable replacement to borrow.

Vitality Medical was founded in 2000 by a registered nurse. We were created with the goal of bringing high quality, affordable medical supplies to the public. We care about your health, wellness and vitality. That is why we offer several programs to make purchasing a concentrator easier.
