Getting started
Set up your WH-02.
Read the complete manual before use. These steps are a setup overview, not a substitute for its instructions or professional guidance.
Check and prepare
Inspect the parts and clean the kit as instructed. Keep the power switch off during setup.
Assemble the kit
Fit the internal funnel and inhalation top, then attach the mask or mouthpiece and air tube as shown in the manual.
Follow professional guidance
Use medication and a treatment regimen only as directed by your doctor or respiratory therapist. Keep the kit upright.
Switch off and disconnect
After use, turn the power off and unplug. Clean and dry the appropriate parts as instructed.
Before you switch on
A few important checks.
Check the device rating label and your power supply. The plug option alone does not establish the voltage rating.
Do not use the device while sleeping or drowsy. Supervise children during use. Do not immerse the compressor or air tube in water.
View the manual and videoCleaning and care
Different parts. Different care.
Switch off and unplug before cleaning. Follow the manual's instructions for each component.
Washable components
Wash the nebulizer kit, mask and mouthpiece in warm water with mild neutral detergent. Rinse and air-dry as directed in the manual.
Let cleaned parts dry before storing them in a clean place.
Keep out of water
Do not immerse the compressor or air tube. Unplug before wiping the compressor with a soft damp cloth.
Do not wash the air filter. Replace it if wet or dirty, and never use the device without the filter.
Do not boil the mask or air tube. For component-specific disinfection, condensation removal and filter replacement, follow the complete WH-02 user manual.

Operating conditions and specification notes
Operating environment: +10°C to +40°C; 30% to 75% RH; atmospheric pressure 86 to 106 kPa.
Manual reference conditions: 20°C, 53% RH, 10 cm from the nebulizer nozzle, using 5 mL of 0.9% physiological saline. Performance varies with conditions and the solution used. The 5 mL figure is a test volume, not a recommended dose or cup capacity.
Power rating: The manual lists separate AC110V and AC220V ratings. This is not a universal-voltage specification. Check the rating on your device before connecting it to power.
Electrical classification: Class II equipment; Type B applied part. These are electrical classifications, not a medical-device risk class or certification claim.
Normal nebulizer output pressure: 60 to 120 kPa.

XB-01Upper-Arm Blood Pressure Monitor View product |
DP-02Arm-Cylinder Blood Pressure Monitor View product |
|---|---|---|---|
| Product PositioningDifferent | Compact and portable for convenient measurement anytime | A balanced choice for everyday home monitoring | A simpler, user-friendly solution for routine home measurement |
| Measurement SiteDifferent | Wrist | Upper arm | Upper arm |
| How It WorksDifferent | An inflatable wrist cuff applies pressure to the wrist artery. Oscillometric technology detects pulse oscillations to calculate systolic pressure, diastolic pressure, and pulse rate. | An inflatable cuff wraps around the upper arm. Oscillometric technology detects pressure oscillations to calculate systolic pressure, diastolic pressure, and pulse rate. | Place the upper arm into the integrated arm cylinder. The device automatically inflates and uses oscillometric technology to measure blood pressure and pulse rate. |
| How to Wear / UseDifferent | Wrap the integrated cuff directly around the wrist | Wrap the separate cuff correctly around the upper arm | Place the arm directly into the integrated arm cylinder; no separate cuff wrapping required |
| Ease of UseDifferent | Easy, but wrist positioning is more sensitive during measurement | Straightforward; correct cuff placement is required | Very intuitive, with fewer cuff-wrapping steps |
| Measurement PostureDifferent | Keep the wrist at heart level; remain still and do not talk | Sit steadily with the upper arm relaxed and supported at heart level | Sit steadily, place the arm naturally into the arm cylinder, keep it supported and remain still |
| PortabilityDifferent | ★★★★★ Excellent | ★★★★☆ Very Good | ★★☆☆☆ Best for a fixed home location |
| Storage ConvenienceDifferent | Compact size, convenient for carrying | Main unit + cuff; suitable for home storage or travel | Integrated design with a larger footprint; ideal for long-term tabletop placement |
| Typical Use ScenariosDifferent | Travel, business trips, office use, quick measurements | Everyday home use, regular blood pressure tracking, family health monitoring | Fixed home monitoring, routine use by older adults, frequent use by multiple family members |
| Ideal UsersDifferent | Users who prioritize portability, travel frequently, or want quick and convenient measurements | Most home users and those who prefer a standard upper-arm measurement method | Older adults, users with limited hand dexterity, and those who prefer fewer cuff-placement steps |
| Key AdvantagesDifferent | Compact & portable / One-touch measurement / Large display | Upper-arm measurement / Adjustable cuff / Flexible home use | Integrated arm cylinder / Fewer setup steps / Large easy-to-read display / Tabletop design |
| Things to ConsiderDifferent | Wrist position can significantly affect readings. Follow the instructions carefully and keep the wrist at heart level. | Correct cuff size and placement are important. A cuff that is too loose, too tight, or incorrectly sized may affect measurements. | Requires more space than compact monitors; correct sitting posture and arm position should still be maintained according to the instructions. |

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.

WH-02 test conditions & model guidance
Source: Ziqing's updated product comparison. WH-02 nebulization rate (0.32 mL/min) and noise (≤55 dB) are customer-confirmed actual measurements. The original WH-02 manual lists approximately 0.16 mL/min and ≤65 dB; it has not been modified. Test conditions for the updated measurements were not provided, so the manual's test conditions are not attributed to these values.
Specifications and portability/practicability ratings are supplied by Ziqing, not an independent performance ranking. Confirm the exact version, power supply and accessories for your device. Unspecified values are not counted as verified differences.
