# MistPro Nebulizer Troubleshooting — Common Issues & Fixes
> Troubleshooting guide for the SonoHealth MistPro Mesh Nebulizer. Fix no mist output, weak mist, charging issues, and mesh clogging with step-by-step solutions.
## No Mist Coming Out
This is the most common issue and is almost always caused by a clogged mesh or incorrect assembly.
**Step-by-step fix:**
1. **Check the mesh** — hold the nebulizer up to a light and look through the mesh. If it appears cloudy or has visible residue, it needs cleaning.
2. **Clean the mesh** — rinse the mesh under warm running water for 30–60 seconds. Gently agitate with a soft brush if residue is stubborn. Do not use sharp objects.
3. **Soak if needed** — soak the mesh component in white vinegar or citric acid solution for 15–20 minutes to dissolve mineral deposits from tap water or medication residue.
4. **Check assembly** — ensure the medication cup and mesh component are properly seated and locked. A loose connection prevents the mesh from vibrating.
5. **Check battery/charge** — a low battery can reduce vibration power below the threshold needed for mist generation. Charge fully before use.
## Weak or Reduced Mist Output
* **Medication cup not filled adequately** — the cup needs to have enough liquid to cover the mesh. Check fill level.
* **Thick medication** — some formulations are more viscous. Try diluting with normal saline as directed by your physician.
* **Partially clogged mesh** — follow the cleaning steps above.
* **Low battery** — charge fully. A weak charge can reduce mesh vibration frequency.
## Device Won't Turn On
* **Battery fully discharged** — connect to USB-C charger and charge for at least 30 minutes before attempting to use.
* **Charging cable issue** — try a different USB-C cable or port.
* **Button not pressed correctly** — press and hold the power button for 2 seconds (not a brief tap).
## Device Turns Off Mid-Treatment
* **Auto-shutoff activated** — the MistPro has an auto-shutoff feature that activates when the medication cup is empty or after a set treatment duration.
* **Low battery** — charge before your next treatment.
* **Overheating** — allow the device to cool for 5 minutes if used multiple times in quick succession.
## Medication Leaking
* **Cup overfilled** — do not fill above the maximum fill line.
* **Cup not properly sealed** — ensure the cup is fully clicked into place.
* **Using device at angle** — for best results, keep the device as upright as possible during treatment.
## Unusual Noise During Use
The MistPro operates near-silently. Any unusual noise may indicate:
* **Debris in the medication cup** — rinse and inspect the cup.
* **Loose component** — check that all parts are fully assembled and secure.
* **Foreign object in mesh** — inspect and rinse thoroughly.
## Cleaning & Maintenance (Prevention)
Regular cleaning prevents most MistPro issues:
| When | What to Do |
| --------------- | ----------------------------------------------------------------- |
| After every use | Rinse medication cup and mesh with warm water; air dry |
| Weekly | Soak mesh in citric acid or white vinegar solution for 15 minutes |
| Monthly | Full disassembly and inspection of all components |
| As needed | Replace medication cup if cracked or permanently stained |
Never use bleach, alcohol above 70%, or abrasive cleaning tools on the mesh. These can damage the mesh holes and compromise mist particle size.
