Read concentration and flow together. Figures above are from the model manuals and depend on operating conditions. They are not a recommendation for your oxygen settings. For medical suitability, follow your healthcare professional's guidance. A dash means the supplied version needs confirmation; it is not zero and is excluded from difference highlighting.
Flow conditions & model guidance
ZY-01: ≥90% applies at the maximum recommended flow of 1 L/min. Do not assume the same concentration at higher settings. The manual describes approximately 30 minutes of startup to reach maximum concentration.
ZY-05: The manual states ≥90% up to the maximum recommended flow of 5 L/min at zero outlet back pressure, reaching the specified concentration within 30 minutes of initial startup. Its ZY-05 graph covers 1–5 L/min. Altitude and operating conditions affect concentration.
SJ-OX1C: The manual specifies 93% ±3% at 1 ±0.2 L/min and 30% ±5% at 6 ±0.5 L/min. The adjustable flow range is not a guarantee of high concentration at every setting. Battery and car-power accessories depend on the package. Confirm compatibility before ordering; no single battery runtime is promised here.
These startup times describe equipment operation, not a treatment duration. Compare the figures with the manual and label supplied with your unit. Weight is not quoted while supplied-version details remain unconfirmed.

Product questions, answered
Oxygen concentrators
How does an oxygen concentrator work?
An oxygen concentrator draws in ambient air and uses components such as molecular sieves to separate nitrogen, delivering oxygen-enriched gas. Flow range and oxygen concentration vary by model.
How do I choose the right oxygen concentrator?
Consider oxygen flow, oxygen concentration, weight, power source, portability and where you plan to use it. For prescribed oxygen or medical use, follow the advice of a qualified healthcare professional.
Is the oxygen concentration the same at every flow setting?
Not always. Oxygen concentration may vary depending on the model and selected flow setting. Please check the specifications for the specific Ziqing model before use.
Does an oxygen concentrator require regular maintenance?
Yes. Follow the product manual to inspect and clean filters, humidification components and accessories as required to help maintain normal operation.
What should I do if the oxygen output seems abnormal?
Check the power supply, filters, tubing connections and accessories first. If the issue continues, stop using the device and contact Ziqing technical support.
Nebulizers
What is the difference between a compressor nebulizer and a handheld mesh nebulizer?
A compressor nebulizer uses compressed air to create aerosol, while a mesh nebulizer uses a vibrating mesh. Mesh models are generally more compact and quieter for portable use.
How should I choose between WH-02, WH-03 and a handheld nebulizer?
For regular home use, WH-02 is a practical compressor option. WH-03 offers a more compact compressor design, while a handheld mesh nebulizer is better suited to users who prioritize portability and quiet operation.
Why is nebulized particle size important?
Particle size is an important performance specification of a nebulizer. Particle distribution varies by model, so refer to the MMAD or particle-size information listed for the specific product.
Do the nebulizer cup, mask and mouthpiece need to be cleaned?
Yes. Clean the applicable accessories after use according to the product manual and allow them to dry completely before storage.
Can I put any liquid into the nebulizer?
No. Do not use liquids that are not confirmed as suitable for the device. For medications or other solutions, follow the product instructions, medication directions and guidance from a healthcare professional.
Blood pressure monitors
What is the difference between wrist, upper-arm and arm-in blood pressure monitors?
They mainly differ in measurement position, cuff design, portability and user experience. Wrist models are compact, upper-arm models use a cuff around the arm, and arm-in models offer an integrated cuff design for convenient operation.
How do I choose between XW-06, XB-01 and DP-02?
Choose XW-06 if portability is a priority, XB-01 for everyday upper-arm home monitoring, or DP-02 if you prefer an integrated arm-in design for fixed-location use.
Why are my blood pressure readings different when I measure several times?
Blood pressure can vary with posture, activity, emotions, measurement interval and cuff position. Follow the manual and measure under consistent, relaxed conditions.
What is the correct posture for measuring blood pressure?
Sit with your back supported, keep both feet flat, remain quiet and avoid moving or talking. Support the measuring arm and follow the positioning instructions for your specific device.
Can a home blood pressure monitor replace a medical diagnosis?
No. Home blood pressure monitors are intended to support routine monitoring and should not be used alone to diagnose a condition or change treatment. Consult a healthcare professional if readings remain unusual or you feel unwell.
Fetal dopplers
What is a home fetal doppler used for?
A home fetal doppler can help users listen to or display fetal heart-related information, depending on the model. It does not replace professional prenatal examinations.
What is the difference between TX-01, TX-02 and TX-05?
The models differ in display, operation and connectivity. Some provide digital or waveform displays, while TX-05 includes Bluetooth/App-related functionality. Check each product page for exact features.
Why might I have difficulty finding a fetal heart signal?
Fetal position, gestational stage, probe placement and operating technique can affect signal detection. Follow the manual carefully and do not make medical conclusions based on a single home-device reading.
Can a home fetal doppler replace prenatal checkups?
No. A home fetal doppler cannot replace ultrasound examinations, prenatal checkups or professional medical assessment.
What should I do if I cannot find a fetal heart signal?
Recheck the operating steps and probe position according to the manual. If you have any concerns about pregnancy or fetal health, contact a qualified healthcare professional promptly.
Hearing aids
How do hearing aids help with hearing?
Hearing aids use microphones to capture sound, process and amplify it, and deliver the adjusted sound to the ear. Features vary by model.
Why does sound feel unusual when I first wear hearing aids?
It can take time to adapt to hearing more environmental sounds. Start gradually and adjust volume or settings according to the product instructions and your listening needs.
Can I use the same settings for both ears?
Not necessarily. Hearing needs can differ between the left and right ear. If personalized adjustment is needed, refer to a hearing assessment or consult a hearing-care professional.
Why does my hearing aid sometimes whistle?
Whistling can be caused by an improper fit, unsuitable ear-tip size, high volume or acoustic feedback. Try refitting the device, checking the ear tip or adjusting the settings.
How should I clean and maintain my hearing aids?
Regularly clean the ear tips, sound outlet and device body, and keep the device dry. Earwax and moisture buildup may affect sound output and performance.
