Philips Respironics Everflo Oxygen Concentrator 5L (USA)


Philips Respironics Everflo Oxygen Concentrator 5L (USA)
The EverFlo™ Oxygen Concentrator is an ultra-quiet upgrade from the EverFlo Oxygen Concentrator. This unit combines the same small size, light weight and low maintenance of its popular predecessor, with the added value of a remarkably improved very quiet sound level. Most oxygen machines carry a sound level of 60 decibels, but the EverFlo™ Q only carries a sound level of 40 decibels.

The Respironics EverFlo is lightweight and small with casters on the bottom of it which makes moving it around a breeze. It has only 2 filters so will require less maintenance. It also generates less heat and less electricity to operate than the older EverFlo oxygen concentrator, therefore saving you money in the long run.

Generally its recommended to change the filter every 3k hours. Outer particle filter needed to be cleaned in weekly basis to ensure smooth flow of air into the system.

Based on daily usage of 12-15 hours, the interval of changing new filter is approximately 4-5 months . If pollution is worsen in some areas such as nearby to the industrial area, the lifespan of filter will be shorten too.
