The CS Ultra HEPA Filter does not restrict airflow under real CPAP conditions.
It works with the AirSense / Aircurve PAPs across the full pressure range.
In both passive and active use, breathing remained natural and unrestricted.
This filter is fully compatible with CPAP therapy and maintains user comfort.

The CSpring ULTRA HEPA Filter delivers high-efficiency air purification with zero hassle. Its advanced 3-stage design targets dust, allergens, and odors—elevating your CPAP therapy with every breath. Breathe cleaner, install in seconds, and stay focused on better sleep.
