Save Money and buy a Used CPAP Machine

Why pay full price for a CPAP machine if you don't have to. Buying a used CPAP machine can be a great way to get a high quality CPAP machine without spending a lot of money. We often get demo CPAP Machines or open box CPAP machines that have zero or very low hours. If the box has been opened it enables us to be able to drop the price significantly.

We get pre-owned CPAP machines in every day so if you don't see what you are looking for in the products below give us a call or email us to find out what we have coming in.
