Many customers ordered our SJ-OX1A home oxygen concentrator. Some customers are not very clear about how to use SJ-OX1A. This guide breaks down the most common questions customers ask, using clear explanations to help you get the best performance from your machine.
1. How Often Should I Replace the Filter?
The filter plays a key role in keeping dust and impurities out of the oxygen system. A clean filter helps maintain stable oxygen purity, and studies show that air filters can reduce airborne particle intake by over 85% when maintained properly.
For the SJ-OX1A, replacement time depends on your local air quality and daily usage. If you live in a city with higher pollution levels, the filter will naturally get dirty faster. As a simple rule:
-
Replace the filter when it visibly turns yellow or looks dirty.
-
On average, we recommend replacing it every 3 months for most households.
A fresh filter not only protects the machine but also ensures more consistent airflow.
2. How Often Should I Change the Water in the Teardrop Humidifier Bottle?
The front water bottle is designed to humidify the airflow so your breathing feels softer and more comfortable. Many users notice a 20–30% improvement in comfort when using humidified air, especially during long sessions.
You can use this humidifier bottle every day. Just make sure to fill it with distilled or purified water, as tap water may contain minerals that leave deposits.
Our recommendation:
-
Change the water daily to keep it clean and fresh.
-
Empty the bottle completely if it has been sitting unused for a full day.
This helps prevent bacteria from building up and ensures a smooth, comfortable oxygen experience.
3. Can SJ-OX1A Use Regular Nasal Cannulas?
Yes. The SJ-OX1A works with standard nasal cannulas commonly used in home oxygen therapy.
However, HIDGEEM includes a soft pure-silicone nasal cannula in the box because silicone is more comfortable for long-term use and reduces irritation compared to regular plastic tubing.
For best hygiene and performance:
-
Clean your cannula often, and
-
Replace it every 4 weeks, or sooner if it becomes stiff or discolored.
4. Can I Use Chargers from Other Household Devices?
No. The SJ-OX1A uses a custom-designed power adapter with voltage and current output specifically matched to this model.
Using chargers not made for the SJ-OX1A may cause:
-
Power instability
-
Reduced lifespan of the machine
-
Potential internal damage
Always use the original HIDGEEM adapter and car charger included with your purchase.
5. Does the SJ-OX1A Come with a Battery?
This model does not include a built-in battery—it is intended mainly for home use. If you need a portable oxygen concentrator with a battery, consider the HIDGEEM SJ-OX1C, which is designed for travel and outdoor activities.
