The SeQual Eclipse 5 Humidifier Kit is your all-in-one humidifier kit. It comes with the Velcro strap to secure your humidifier bottle, a humidifier bottle, and tubing to go from your bottle to the concentrator. Simply Velcro the strap around the concentrator, insert your humidifier bottle with water, connect the tubing and you are good to go. When using a continuous flow, it is normal to experience dry, sensitive, and/or irritated nasal cavities. When oxygen is continuously pumped into your nose via the nasal cannula, it's easy to see why your nostrils may become irritated. The humidifier kit combats those side-effects by adding moisture to the oxygen you are breathing in. This kit provides a simple solution for patients who experience dryness or irritation from continuous flow oxygen therapy.
