DUAL WALL NASAL PILLOW DESIGN Swift FX for Her Nasal Pillows are equipped with a soft inner wall and outer wall for added support and comfort. The cushion base has a soft, flexible air chamber that provides outstanding flexibility, and stability during sleep; even at higher therapy pressures. SOFT COMFORT ALL AROUND The level of comfort a mask provides can make all the difference to the overall success of your therapy; this fact was not lost on ResMed during the design of the Swift FX for Her Nasal Pillow CPAP Mask. ResMed has designed the Swift FX for Her with a flexible, adaptive, soft pillow, and headgear; to include soft pink felt headgear straps pads, with every purchase. STABLE, YET SOFT AND SECURE The Swift FX for Her soft pillow design, as well as exceptionally soft flexible materials used in the headgear, creates a Nasal Pillow mask that adapts to your every sleep position. The flexible nasal pillows and headgear conform to facial contours and features. Because of the minimalist design, the headgear works perfectly for active sleepers, and side sleepers. The Swift FX for Her patented Spring-Flex lightweight tubing works to minimizes tubing torque, or pull, yet another design feature that provides maximum comfort. Unique Dual-wall pillow design also adds flexibility to help maintain a consistent, secure seal. Whisper-Quiet Vents Another thoughtful ResMed design element is the output ports or vents. The Swift FX for Her diffuses the airflow away from the user and your sleep partner. In addition to this, the air diffusers also act to significantly reduce the overall noise output of the mask - only 25 dBA, one of the quietest in the industry. EXCEPTIONAL EASY OF USE In conclusion, with soft adaptive pillows, flexible lightweight headgear with felt pads, quiet air diffusers, and overall minimalist design, we think the ResMed Swift FX for Her is one of the best-in-value nasal pillow CPAP mask systems on the market.
