VH-3 Home Oxygen Concentrator — Compact, Quiet, and High-Performance
Breathe easier every day with the VH-3 — a lightweight, intelligent home oxygen concentrator designed for comfort, efficiency, and uninterrupted oxygen therapy.
Continuous High-Concentration Oxygen Flow
VH-3 delivers steady, continuous-flow oxygen at up to 90% purity, with an adjustable flow rate from 1–7 to suit your personal needs. Its high-efficiency lithium sieve ensures strong adsorption and a consistent oxygen supply for maximum effectiveness.
Integrated Nebulizer Function
Equipped with a built-in nebulizer and included kit, VH-3 allows you to receive both oxygen and nebulizer therapy simultaneously — a convenient, comprehensive respiratory care solution.
Whisper-Quiet & Energy-Efficient
Operating at just 42 dB, VH-3 is perfect for nighttime use without disturbing your rest. Its pure copper, oil-free compressor is built for endurance, running continuously for up to 72 hours while consuming less power.
Our pet-friendly oxygen concentrators VH-3 can all be used for pet oxygen therapy (commonly at a flow rate of 1L). Common starting flow rates for pets: Pets (especially cats and small dogs) typically require much lower oxygen flow rates than adults. Veterinarians most commonly recommend a starting flow rate of 1 liter per minute (1 L/min) for pets. This flow rate is sufficient to meet the basic oxygen therapy needs of most small pets while avoiding the irritation or discomfort that excessive flow rates can cause to their delicate respiratory tracts (such as oxygen-induced lung damage).
Auto-Humidification & 10-Layer Filtration
Say goodbye to dry oxygen — VH-3 automatically humidifies the air without needing manual water refills. The advanced 10-layer filtration system removes impurities, delivering clean, safe oxygen with every breath.
Lightweight & Easy to Move
Weighing only 10.58 lbs, VH-3 is our lightest home oxygen concentrator yet. Its compact body and ergonomic design make it easy to move from room to room or even to your car for use on the road.
User-Friendly Features
Large digital panel with hidden power-saving display
Sleep mode and timer function (customizable oxygen duration)
SOS function and infrared remote control for added convenience
Spare filter pad included for easy maintenance
Prioritize your respiratory wellness. Choose VH-3 for a quiet, compact, and dependable oxygen therapy experience — anytime, anywhere.
❗ Filter and Accessory Maintenance
Air Intake Filter: The intake filter cotton isnot washable. It should be replaced after100–200 hours of use, or immediately if it appears dirty.

--Regularly maintain the appearance of the oxygen concentrator and carefully wipe around the vents. To remove dirt, rub the surface lightly. --Clean the nasal cannula at least once a week. If it is used daily, it is best to change the nasal cannula every two months. If you don't use it frequently, replace it every three to six months. --The filter of the oxygen generator can remove dust, dirt, and pollen from the air. Cleaning the filter once a month can extend the service life of the unit.

What is the difference between continuous flow and pulsed flow?
Pulse flow concentrators deliver the required oxygen only when you breathe in. While continuous-flow oxygen concentrators provide a constant flow of oxygen, regardless of whether you are inhaling. Continuous flow is suitable for those who need a non-stop oxygen supply, while pulse flow is mainly used on portable oxygen machines for lower power consumption and longer battery life.
What is a nebulizer and nebulizer therapy?
VH-3 home oxygen concentrator has a nebulizer function. A nebulizer is a medical device used in respiratory therapy to deliver medication directly into the lungs in the form of a mist. It converts liquid medication into fine particles that can be easily inhaled by the patient. Nebulizer therapy involves using a nebulizer to administer medication for the treatment of respiratory conditions such as asthma, COPD, cystic fibrosis, and more. It is suitable for patients of all ages, and is highly effective in delivering medication directly to the lungs, providing quick relief and targeted treatment.
Can I use VH-3 overnight?
Yes. The high-quality compressor in Vh-3 allows for continuous use up to 72 hours. It operates quietly with a noise level as low as 42 dB, so you can sleep soundly while using it over the night.
Can I use VH-3 with a CPAP machine?
Yes, VH-3 is compatible with common CPAP machines. Yet we recommend you check the specifications of your CPAP machine to confirm its compatibility with oxygen machines.
We bought this model for travel mostly hotel breaks It’s easy to lift into the car and is less noisy than the larger machine we have at home Wirks with our Cpap for overnight use All in all good value
Seems to work as advertised, can’t really confirm the output is as the display, seems too stable outputting 60% purity constantly, but we bought it to connect to a dog mouthpiece and give our elderly dog ( with lung disease) oxygen overnight. Seems to work as he now sleeps through the night.
The machine is so well-made and produces enough oxygen to help her cope with her complaint.
The machine also comes with a defibrillator function, which is a bonus. The machine is well-made and produces enough oxygen to help her manage her condition. Additionally, it includes a defibrillator function, which is a bonus.
We bought this oxygen concentrator to use with our dog who is in the later stages of heart failure. It is reassuring to have something to help him when he is struggling for breath. It is all we expected and does exactly what is claimed. Hard to compare with anything as it is the first time we have ever used anything similar to this.
It’s nice and compact. Doesn’t dominate the room. Easy to move around. And best of all very quiet. You don’t even know it’s there . My only concerns are the tubing from mask to machine is very short, and the nasel canulla does not fit very well.
The machine worked as expected, was quiet and produced the oxygen level that we were looking for. Unfortunately, it didn't help my mom with her breathing issues.
This has been a great addition to my pursuit of health. The machine is easy to use and set up. I highly recommend it for someone who isn't getting enough oxygen at night.
What a great little machine. It is quiet enough as not to disturb sleep. I absolutely love this!!!!! Small enough to move around, wish it had a handle, and can be used in the vehicle. I didn't expect such quality for the price. I think the posts about it over heating are because it is too close to a wall to vent properly. It used as instructed you won't be disappointed. LOVE IT!!!!!!
Well packaged for shipping, arrived on time, in perfect condition when removed from box. Unit and remote works as described. I have an air cleaner in the room so noise blends together. Unit is not too loud, depends on your perspective. I only have unit on while I am using it, I turn off power switch once the fan cools unit and shuts off. The sleep mode works as advertised and does not light up the room. Very happy with the purchase.
The VH-3 is everything advertised and specified on the website. I have tested both flow and O2 concentration percentage and they match the specifications. I use the concentrator at night in conjunction with my Resmed AirCurve 10 ASV pap machine to mitigate central and sleep apnea and the VH-3 appears to be doing the job of helping to keep my SPO2 levels in the 90's as opposed to the mid 70's without. I have used a recording pulse oximeter overnight with both. The VH-3 replaces a large Phillips unit that is much bigger and noisier.
It took me awhile to use it I wanted to get extra O2 tubes and something to clean them with. It is quieter than I thought it would be - I was using the nasal cannula wrong no instructions for that - I love the machine it helps me almost every night, so glad I have it - I would suggest a different hose connector though one that is tapered so it is easier to put the tubing on bless youall.
The machine came quickly was easy to set up and easy to move around this was very important to me. I do wish it had a better handle so I could pick it up with one hand, other than that I am very happy
Received the VH-3 Concentrator within the advertised delivery dates. This unit is extremely quiet and has numerous features that make it an appealing product. Liked it so much that I purchased a second unit.
The equipment meets the expectations for my daughter. However, the instructions are very confusing, even for me, a medical professional, to understand. In general, it is best just to recommend the liter flow rather than O2 %.
So far, I am happy with my purchase. I personally didn't like the cannula provided, but was easy to attach my own. It keeps a steady flow and is very efficient for the size.
