Philips EverFlo oxygen concentrator is a trustworthy and cost-effective mode of oxygen therapy. It is designed in such a way that the overall maintenance cost is relatively low.

It has just two filters – an internal filter, which is a minute disc that requires simple inspection during routine maintenance operations and an external filter that can be changed in minutes. Maintenance does not require any special skills or tools.

The device is light weight and hence it is easy to store and transport. This also reducing the chances of any injury. The humidifier bottle platform is flexible and can accommodate bottles of any style. It also has a recessed flow meter, which decreases the chances of accidental breakage.
