Reasons to replace your CPAP/BiPAP equipment.

1.) CPAP Supplies are Disposable - Your CPAP mask, headgear, and tubing aren't meant to last!
2.) Cushions Lose Their Seal Over Time - If you have to continually tighten and overtighten the headgear to maintain a seal with your mask, it will not fit comfortably and you can actually harm yourself in the process.
3.) Bacteria! - This becomes more difficult to eliminate as a mask ages.
4.) Dirty Filters Damage CPAP Machines - The filters in a CPAP machine need to be replaced regularly.
