ResMed Swift FX Nasal Pillow Replacement, Large

I've been using the Swift FX for several years now. It's not as comfortable as the P-10, but it is more secure on the head and I much prefer having the hose swivel of the Swift FX. Also, the straps last longer. The nasal pillow of the Swift FX is very comfortable. I am on a very tight budget, and I've found the nasal pillows will last much longer between replacement that ResMed recommends. Just keep them clean, but do so without using cotton swabs every time since using them too often makes the thinly spaced silicone of the nose cones stretch out of shape.
