1. Will this affect my CPAP pressure or therapy?

No. The CS Ultra mounts outside your CPAP’s air intake and does not interfere with internal pressure sensors or airflow delivery.Does this replace my regular CPAP filter?

The CS Ultra provides advanced HEPA filtration at the CPAP air intake, which many users choose to use in place of standard internal filters. However, because every machine is different, we recommend reviewing your manufacturer’s maintenance guidelines before removing or discontinuing internal filters.How do I install it?

Remove the existing air filter grill from your CPAP. The CS Ultra connects directly to the intake using the included adapter. Installation is quick, tool-free, and fully external.

Note: Always follow your CPAP manufacturer’s instructions regarding filter replacement or internal filter use.Test DATA Summary: CS Ultra HEPA Filter vs. No Filter
