| Changed weekly, your air quality is near perfect. Looking at the Filter Media it is easy to see its effectiveness. The 3 pads (on the right) removed from filter housings are:
A - 0hrs (NEW)
B - 110hrs (approx 2 weeks of nightly use)
C - 250hrs (approx 4 weeks of nightly use)
All filters where used in a clean Hospital environment at an average of 10cmH20 of pressure. What are you breathing in where you live?
As a patient relies on the devices to supply them with air for up to 8 hours during the night and they are normally taking in a greater volume of air than a person breathing without the CPAP/BiLevel Machine, studies have suggested that CPAP users can suffer greater instances of upper airway problems.
The SureGard® CPAP filter contains the HyperGard® "TEC200gm" filter media published to be the most effective available for respiratory use in many clinical conditions. |
