This filter will connect to your CPAP where your CPAP tubing would connect. Add this filter, then connect the CPAP tubing to this filter. If you use a heated CPAP tube, then you may need to connect this filter between the mask and the cpap tubing.
If you use an auto CPAP, consider that this filter may alter the cpap machines ability to auto adjust your pressure. If your average pressure is 7cm H2O or less, this filter is not recommended.
This filter will effectively filter bacteria, and any tiny particles, however will not filter gases.
