I manage a nursing home, and we recently added the RE-R1L to our medical equipment. It's been a hit with both staff and residents! The touchscreen is simple for residents to use (even those with dexterity issues), and the remote control lets staff adjust settings without disturbing residents. The 1-8L flow meets all our residents needs, from mild to severe respiratory support. The nebulizer function is used daily for congestion, and the <40dB noise keeps rooms quiet. The 8-stage filtration is important for infection control, and the machine is easy to clean between uses. At 8.8 pounds, staff can move it between rooms quickly, and the compact size fits in small resident rooms. We are buying more soon!

I was nervous about buying a medical device online, but the RE-R1L is 1-year warranty and DEDAKJ's customer service put me at ease. When I had a question about replacing the filter, their team responded within 2 hours with a step-by-step guide and a video. The machine itself is fantastic: 5L/min flow with 90% concentration for my asthma, quiet <40dB operation, and a nebulizer that works better than my old one. The automatic humidification solves my dry air problem, and the remote control is convenient. The compact size fits on my desk, and the built-in handle makes it easy to move. I am so glad I chose this worth every dollar!

My oxygen needs change depending on my activity level (2L when resting, 7L when exercising), and the RE-R1L's precise 1-8L adjustment lets me set it perfectly. The touchscreen shows the exact concentration (from 30% to 93%), so I know I am getting the right amount. When I exercise, I crank it up to 7L, and the concentration stays at 93% no drops. The nebulizer function is great post-workout to soothe my lungs, and the automatic humidification helps with post-exercise dryness. The machine is quiet enough to use while working out (I have a home gym), and the built-in handle lets me move it to the gym area easily. The 8-stage filtration keeps the air clean, which is important when I am breathing heavily.

I love taking short walks around my neighborhood, but my old concentrator was too heavy to carry. The RE-R1L is 8.8 pounds light enough to put in a small tote bag and carry for 30 minutes. I use 3L/min while walking, and the <40dB noise doesn't attract attention. The built-in handle makes it easy to grab and go, and the compact size fits in the tote without bulging. The oxygen concentration stays at 88% even when I am moving, and the automatic humidification keeps my throat from drying out in the wind. I also use the nebulizer before walks if I have congestion, no need to wait at home. This machine has helped me stay active, which is great for my overall health!

My doctor recommended strict oxygen therapy times (6 hours at night, 3 hours during the day), and the RE-R1L's timer function keeps me on track. I can set it for 0.5-12 hours, and it beeps softly before shutting off no more guessing how long I have used it. The touchscreen shows the remaining time, so I can plan my day. I use 5L/min with 93% concentration, and the continuous flow never drops. The automatic humidification keeps my airways comfortable, and the <40dB noise is quiet enough for reading. The remote control lets me pause or adjust the timer without getting up, which is great on lazy days. This machine has made my therapy routine so much easier!
