I need nebulizer treatments before bed and oxygen therapy while sleeping. This home oxygen concentrator does both in one unit. The continuous flow at 3 liters per minute at 93 percent oxygen concentration works all night. The nebulizer mode with the included set delivers my medication perfectly. The 40 decibel noise does not wake my spouse. The timer function shuts off the nebulizer mode automatically. The voice guidance confirms the mode switch. The remote control lets me start the nebulizer from bed. This all in one device simplified my nightly routine tremendously.
Buying a separate nebulizer would cost over 50 dollars. This home oxygen concentrator includes the nebulizer set at no extra cost.

This home oxygen concentrator works perfectly at 7 liters per minute continuous flow with 93 percent oxygen purity. The touchscreen remote control and voice guidance are excellent. The 40 decibel noise is very quiet. The only improvement would be an internal battery backup for power outages. I bought an external UPS separately.
