I manage a nursing home, and we recently added the RE-Q1L 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-Q1L 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-Q1L'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-Q1L 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!

I run a small clinic, and we needed a portable oxygen concentrator for exam rooms and the RE-Q1L is perfect. It's lightweight (8.8 pounds) so staff can move it between rooms easily, and the 1-7L flow adjusts to meet different patients needs (from 2L for mild cases to 8L for severe). The nebulizer function is used daily for patients with congestion, and the micron mist is effective. The <40dB noise keeps exam rooms quiet, and the large LED display lets patients see their settings. The 8-stage filtration is important for infection control, and the machine is easy to clean between patients. We have had it for 2 months, and it's never had an issue, highly recommend for medical facilities!

I hate complicated cleaning routines, so the RE-Q1L's simplicity is a relief. The touch panel wipes clean with a damp cloth (no hard-to-reach crevices), and the inlet filter is easy to remove and replace just twist the cover and pop it out. The nebulizer cup is dishwasher-safe, which saves time. I use 3L/min oxygen daily, and the machine stays clean with minimal effort. The <40dB noise is quiet enough to use while cooking, and the compact size fits on my kitchen counter. The automatic humidification works great,no more refilling water tanks like my old machine. The 1-year warranty and 7-day money-back guarantee made me feel confident in my purchase, and it's lived up to every expectation.

ESPECTACULAR!!!! Todo funciona muy bien...

My doctor recommended strict oxygen therapy times (6 hours at night, 3 hours during the day), and the RE-Q1L'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!

At 82, my eyesight isn't what it used to be, but the RE-Q1L's large LED display is crystal clear, no squinting or grabbing my glasses. It shows flow rate, concentration, timer, and humidity levels in big, bright numbers. The touch buttons are responsive and easy to press (no hard pushing!), and the remote control has equally large buttons. I use 2L/min for mild support, and the machine delivers consistent oxygen. The nebulizer function is gentle on my lungs, and the automatic humidification keeps my throat from getting dry. The built-in handle is comfortable to hold, and at 8.8 pounds, I can move it to my favorite chair without help. This machine is designed with seniors in mind, and it shows!

I used to have a bulky nebulizer that took forever to set up, but the RE-Q1L's built-in nebulizer is faster and more effective. The micron-level mist is finer, so my meds are absorbed better, and I can use it while on oxygen no switching devices. I use the nebulizer twice a day for my COPD, and it only takes 10 minutes. The touchscreen lets me set the nebulizer timer separately from the oxygen, which is convenient. The machine also delivers 5L/min oxygen with 90% concentration, which keeps me breathing easy. At 8.8 pounds, it's lighter than my old nebulizer + concentrator combo, and the built-in handle makes carrying it simple. The 12-hour auto-shutdown is great for when I am tired and forget to turn it off.

I need oxygen 24/7, and the RE-Q1L has been 100% reliable since I bought it. It runs continuously without overheating, and the flow rate (6L/min) and concentration (93%) never fluctuate. The automatic humidification keeps my airways comfortable, even during long nights, and the <40dB noise is quiet enough for sleep. The touchscreen is easy to use even when I am tired and the remote control lets my caregiver adjust settings without disturbing me. The 8-stage filtration is a must for me, as I am prone to infections. The machine is also easy to maintain: just replace the filter every 3 months and wipe the touch panel. I can't imagine life without it!

My family loves road trips, but my oxygen needs used to hold us back. Now, with the RE-Q1L and a 12V to 110V car inverter, we can travel anywhere! The machine runs smoothly in the car, delivering 4L/min with 90% concentration. The nebulizer function is handy if I get car sick (which makes my breathing worse), and the <40dB noise doesn't drown out the radio. The built-in handle lets me move it from the trunk to the backseat easily, and the compact size fits between the seats. I set the 4-hour timer for long drives, and it shuts off automatically when we stop. We just took a 6-hour trip, and it worked perfectly no more missed adventures!

I have spent hundreds on respiratory equipment, but the RE-Q1L is the best investment I have made. It's 2-in-1 (oxygen + nebulizer) so I saved money on a separate nebulizer. The 1-8L flow meets my changing needs, and the 93% concentration keeps me breathing easy. The <40dB noise lets me sleep and work without disruption, and the automatic humidification solves my dry air problem. The remote control and timer make it easy to use, and the 8-stage filtration keeps the air clean. The compact size and built-in handle make it portable, and the 110V/220V power works anywhere. This machine has improved my quality of life more than I ever expected 5 stars isn't enough!

I am very sensitive to air pollutants, so the RE-Q1L's 8-stage filtration system was a big selling point and it doesn't disappoint! It filters out dust, bacteria, viruses, and odors, so I know the oxygen I am breathing is pure. I use 5L/min daily, and I can feel the difference no more stuffy nose or irritation. The filter is easy to replace (just twist the cover and swap it) and lasts about 3 months. The machine also has a nebulizer with micron mist, which is great for my sinus issues. At 8.8 pounds, it's portable enough to take to my daughter's house for weekends, and the 110V/220V power means it works anywhere. The 1-year warranty gives me peace of mind too.

I appreciate that the RE-Q1L comes with a QC Certificate knowing it's passed quality checks gives me confidence in its performance. The machine lives up to the certificate: 6L/min flow with 93% concentration, quiet <40dB operation, and a nebulizer that's effective. The automatic humidification works as advertised, and the 8-stage filtration keeps the air clean. The touchscreen is responsive, and the remote control works from across the room. The built-in handle is sturdy, and at 8.8 pounds, it's easy to carry. The 1-year warranty and 30-day free return policy are added bonuses. This machine is high-quality, and the QC certificate proves it no regrets buying it!

I often need to tweak my oxygen flow rate in the middle of the night, and getting out of bed was a hassle with my old machine. The RE-Q1L's remote control (which works up to 8 meters!) lets me adjust flow from 3L to 4L without leaving my pillow. The remote also has a timer button if I wake up early, I can set it to shut off in 1 hour instead of waiting for the 12-hour auto-shutdown. The oxygen concentration stays consistent, even when I change the flow, and the automatic humidification keeps my throat from drying out. The machine is quiet enough that my partner doesn't notice it, and the LED display dims slightly at night so it doesn't glow in my eyes.

The included 3m rubber hose is long enough to let me move around my bedroom from my bed to my dresser to my chair without disconnecting the oxygen. It's flexible and doesn't kink, so the flow never stops. I use 4L/min with 90% concentration, and the hose delivers oxygen evenly. The water trap in the hose is a great feature no more water buildup. The nebulizer function uses the same hose, so I don't have to switch to a shorter one. The <40dB noise is quiet enough to use while getting dressed, and the automatic humidification keeps my throat comfortable. The machine is compact enough to stay on my nightstand, and the built-in handle makes it easy to move if I need to. This long hose is a game-changer for my mobility!

I have a tiny apartment, so space is a big concern. The RE-Q1L's size (9.4-5.9-10 inches) is perfect it fits on my nightstand without taking up too much room, and it's small enough to store in the closet when not in use. At 8.8 pounds, I can move it to the living room or kitchen easily using the built-in handle. I use 2L/min for mild respiratory support, and the <40dB noise is so quiet I forget it's on. The nebulizer function is great for allergies no more bulky nebulizers cluttering my space. The 8-stage filtration keeps the air clean, which is important since I have allergies. This machine is a space-saving miracle!

I accidentally knocked the RE-Q1L off my nightstand (about 2 feet high), and I panicked but it still works perfectly! The casing is sturdy, and there's no damage. I use 5L/min with 92% concentration, and the flow and concentration are still consistent. The nebulizer function works just as well, and the automatic humidification is unaffected. The built-in handle is still secure, and the touchscreen didn't crack. This machine is built to withstand small accidents, which is great for someone like me who is a little clumsy. The <40dB noise is still quiet, and the LED display is clear. I am impressed with its durability worth every penny for the peace of mind!

I need high-flow oxygen (7-8L/min) for my lung condition, and most home concentrators only go up to 5L. The RE-R1L's 1-8L adjustable flow is a game-changer it delivers 8L/min with 93% concentration, which keeps me breathing easy all day. The nebulizer function is a bonus when I have a chest infection, I can use it to take my meds without extra equipment. The 12-hour timer is perfect for my daily routine: I set it for 8 hours at night and 4 hours during the day. The remote control lets me adjust settings from across the room, and the large LED display is easy to read even with my glasses. The machine runs 24/7 when I need it, and it never overheats.

I have sleep apnea and need both CPAP and oxygen, so I was thrilled to find the RE-Q1L works with my CPAP machine. I connect the oxygen tube to my CPAP, set the flow rate to 2L/min, and it delivers consistent oxygen all night. The <40dB noise doesn't interfere with my CPAP's noise, so I sleep soundly. The automatic humidification works with the CPAP too, no more dry air. The 12-hour timer is perfect for my sleep schedule, and the remote control lets me adjust the flow if I wake up. The machine is compact enough to fit next to my CPAP, and the built-in handle makes moving both easy. The 8-stage filtration keeps the air clean, which is important for my lungs. This combo has changed my sleep for the better!
