Review of HUKOER Top Grade Portable Household Oxygen Concentrator Generator 1L Oxygen Making Machine Air Purifier 90% High Purity 6L Flow (white with black): ✅ Price comparison ✅ Customer reviews ✅ Product information: delivery method, weight, battery.
As with many of the Portable Oxygen Concentrators, this brand brands products it doesn’t manufacture. The company that makes this model is Shanghai Yiran Trading. It also makes some of the more familiar brands in this category. It means that you can find the same quality products under different brand names and different price points.
HUKOER Oxygen Concentrator Models
After a few searches online, I found a few models sold with the HUKOER brand. Some are not even labeled. Because these are sticker models, there’s little connection between them – they look and function differently. It could be a plus and a minus. The upside is the models cover a wider potential audience. The downside is there’s no clear distinction and no tiers between models – there’s no one model that’s clearly an upgrade to the other. Can get confusing.
HUKOER J11 Portable Oxygen Concentrator 1-5L/min


This model is identical to TTLIFE’s ZH-J11 in its form and function.
As with TTLIFE, this is the entry model that HUKOER offer. It is the cheapest, and costs £250. But the differences in price between models are minor.
It delivers an adjustable continuous flow of 1-5 l/min. This range of oxygen flow is on the lower end of the scale for similar machines, in price and portability. Oxygen purity is 30%-90%(±3%), and this is a category standard range. The continuous airflow and purity are 1 l/min at 90%, 2 l/min at 70%, 3 l/min at 50%, 4 l/min at 40% and 5 l/min at 30%. Purity drops significantly when airflow rises.
The noise level is an acceptable 45dB. It’s a noticeable hum, but something most people would get used to quickly.
The size of the machine is 32.5cm L x 19.8cm W x 32.3cm H, and its weight is 6kg. This is a small form factor and lightweight. The handle at the top will make it easy to move around the house or car (requires a transformer).
There’s a small blue LCD screen with relevant information and a remote control with the basic functionalities – timing, anion, mode, on/off.
The package comes with:
- HUKOER J11 portable oxygen concentrator and power cord
- Operation manual
- IR remote control
- Injector
- Oxygen cannula and headset
HUKOER Quiet Portable Oxygen Concentrator 1-5L/min


I mentioned at the top that the product lineup that HUKOER is offering is confusing, and this model is a good example. Basically, it delivers similar performance at a similar price (£270) to the J11 model but is quieter and slightly heavier. It also doesn’t come with remote control.
The model’s continuous flow rate is 1-5 l/min, and its peak purity is 90%(±3%). Peak purity comes only at the lowest airflow – 1 l/min. If you need a higher flow rate, you’ll need to settle for a much lower purity. Purity level drops significantly with the raise of airflow. The continuous airflow and purity are 1 l/min at 90%, 2 l/min at 80%, 3 l/min at 60%, 4 l/min at 45% and 5 l/min at 30%
This model’s main strength is it’s working noise level. At 38db, this is one of the quieter POCs at this price point. There’s still a humming noise, but it is less noticeable. It wouldn’t take long to get used to it.
Size and weight are not that different than the other two models on this list. Machine’s dimensions are 32.5cm L x 19.6cm W x 32.5cm H, and its weight is 7.4kg.
There’s a small blue backlit LCD screen with a few buttons below it. The buttons control time settings, oxygen concentration, airflow, oxygen absorption, and on/off switch.
The package comes with:
- Oxygen concentrator machine with a power line
- Operation manual
- Nasal cannula and headset oxygen cannula
- Nebulizer
- 2 replacement filter Cotton and 1 HEPA filter
- Replacement fuse
HUKOER ZY-1A Oxygen Concentrator 1-7L/min


This model is identical to TTLIFE’s ZY-1A, and there’s no branding to tell the two apart.
Of the three models, this is the top tier one. It goes for £280, which is slightly more expensive than other models.
These POCs delivers an adjustable continuous flow of 1-7 l/min. This flow range is the higher output in the product lineup. Oxygen purity is 30%-90%(±3%), which is a standard for home-use machines. You’d get the same range as other machines, but the main difference is with purity at every flow tier. The continuous airflow and purity are 1 l/min at 90%, 2 l/min at 50%, 6 l/min at 30% and 7 l/min at 25%. The drop in purity as airflow raises is noticeable and potential buyers should consider their airflow and purity needs before completing a purchase.
Noise level for this models is relatively high at ≤60db. I assume the motor has is straining to deliver the 7l/min flow and so it is louder than other model, even from other brands and manufacturers. If you need this machine during sleep, consider a quite model.
The size of the machine is 35cm L x 22cm W x 32cm H, and its weight is 5.2kg. This is a small form factor, even if bigger than other models. The weight is a strong point as it is on the lower range, and about 1kg lighter than other HUKOER models. The handle at the top doesn’t look comfortable, but it will still make it easy to move around the house or car. If you want to use it outside, you’ll need an outlet or a transformer for a car.
Another plus for this machine is the large touch LCD screen at the top. When the machine is on, the buttons light up and are clear and easy to read. There’s color coding for an even friendlier user experience. The screen shows purity, flow rate, timing, counts, anion, voice, on/off.


The package comes with:
- HUKOER ZY-1A portable oxygen concentrator and power cord
- Operation manual
- IR remote control
- Disposable nebulizer assembly
- Oxygen cannula
