Advantages
Weight - An important advantage of this model is its low weight compared to its predecessors, i.e. traditional oxygen cylinders - EverFlo weighs only 14 kg. The camera is compact and ergonomic, and its shape does not pose any difficulties in transport. Thanks to the handy handle and appropriate proportions, the mentioned model works perfectly not only when carrying it over short distances, but also when transporting it by car.
Efficiency - Thanks to its efficient operation, which guarantees visible savings, it is currently the most frequently chosen model for home use. Just half an hour after starting the equipment, we obtain an oxygen supply of 96%.
An economical oxygen compressor consumes only 350W of electricity, which means that an hour of its operation costs approximately 21 cents. Thanks to this, the device does not heat up and operates in the temperature range of 16 - 32 ° C.
Proven quality A proven medical device that enjoys particular recognition among both patients and doctors is the EverFlo concentrator - the most modern model in its product category, based on advanced medical technologies. In 2008, EverFlo won the title of the best oxygen concentrator in an independent study by HME Home Medical Equipment.
Service - Low maintenance requirements reduce service costs. No filter replacement required by a home care specialist for two years. The patient never needs to replace the filters.
