Mask Cushions, Pillows & Seals

The cushion or silicone seal is the most critical component of your CPAP mask, acting as the direct barrier between the therapeutic air pressure and your skin. Because it is exposed to facial oils, moisture, and skincare products every single night, even the highest-quality silicone, gel, or foam seals will naturally degrade over time. As they soften and lose their structural integrity, micro-leaks develop, forcing the machine to work harder and causing irritating air drafts to blow into your eyes. Replacing your cushion regularly is essential for maintaining therapy efficiency and stopping skin irritation in its tracks.

At S-Med, we stock an exhaustive inventory of authentic replacement cushions, nasal pillows, and seals directly from industry leaders such as ResMed, Löwenstein, and Fisher & Paykel. Whether you need a dual-wall silicone cushion for your full face mask, a pair of ultra-soft nasal pillows to refresh your minimalist setup, or an advanced memory foam seal designed to reduce red facial marks, we have the exact size and model to perfectly match your existing frame.

With over 23 years of clinical excellence supporting NHS Trusts and private sleep clinics throughout the United Kingdom, S-Med stands for trusted quality.
