If you’ve noticed your humidifier spitting out water instead of creating a fine mist, you’re not alone. This common issue can be frustrating, especially when you’re trying to maintain the right humidity levels in your home for comfort and health.
Humidifiers are designed to add moisture to the air, but when something goes wrong, it can lead to water droplets being expelled instead.
Understanding the causes behind this problem is key to fixing it and ensuring your humidifier functions properly.

Why is My Humidifier Spitting Out Water?
Your humidifier may be spitting out water due to overfilling, which causes water to be expelled with the mist. Additionally, if the ultrasonic membrane or evaporative wick is dirty, it can cause water droplets to form in the mist. Resolving these issues by cleaning and proper filling can typically rectify the problem.
Causes of a Humidifier Spitting Out Water
A humidifier might spit out water due to several reasons, mainly related to its operation, maintenance, and the condition of its components. Here are a few causes:
- Overfilling: Filling the water tank beyond its capacity can lead to water spitting, as excess water might be expelled along with the mist.
- Dirty or Damaged Ultrasonic Diaphragm: In ultrasonic humidifiers, a dirty or damaged diaphragm can lead to the formation of water droplets in the mist, causing water spitting.
- Clogged or Dirty Filter: If the humidifier has a filter that’s clogged or dirty, it may allow water droplets to pass through, leading to water spitting.
- Incorrect Settings: Some humidifiers allow adjustments to the mist output. When set to a high output level, some models may spit water, especially if the room’s humidity level is already high.
- Poor Quality Water: Using water with high mineral content or impurities can lead to the formation of larger water droplets, causing the humidifier to spit water.
- Faulty or Damaged Components: Any damage or fault in internal components like valves or the fan can lead to improper operation and result in water spitting.
- Condensation Buildup: If the air near the humidifier is saturated and cannot hold more moisture, excess water may condense and be expelled as water droplets.
- Lack of Regular Maintenance: Failure to clean and maintain the humidifier regularly can lead to the accumulation of mineral deposits and bacteria, potentially causing water spitting.
Note: Addressing these issues promptly can help in avoiding water spitting and maintaining the humidifier in optimal working condition. Regular cleaning, using distilled or demineralized water, and adhering to the manufacturer’s guidelines can significantly mitigate these problems.
How to Prevent a Humidifier From Spitting Out Water
Preventing a humidifier from spitting out water is crucial for its optimal operation. Below are several preventive measures:
- Regular Cleaning: Regularly clean the humidifier to remove mineral deposits and bacteria, following the manufacturer’s cleaning instructions. This prevents the formation of water droplets in the mist.
- Use Distilled or Demineralized Water: Using water with a low mineral content reduces the likelihood of water spitting and prolongs the lifespan of the unit.
- Avoid Overfilling: Fill the water tank only up to the indicated maximum level to prevent water from being expelled with the mist.
- Regular Maintenance: Regularly inspect and replace damaged or worn-out components, such as filters and wicks, and adhere to maintenance guidelines provided in the manual.
- Adjust Settings: Set the humidifier to a suitable mist output level according to the room’s humidity level and size. Avoid high settings in smaller rooms or in rooms with high humidity.
- Positioning: Position the humidifier in a suitable location, away from walls, furniture, and electrical appliances, to allow for proper air circulation and moisture absorption.
- Maintain Optimal Humidity Levels: Monitor room humidity and adjust the humidifier settings accordingly to maintain a balanced humidity level (ideally between 30% and 50%) and prevent condensation and water spitting.
- Use Manufacturer Recommended Parts: Use only the parts and accessories recommended by the manufacturer, such as filters and wicks, to ensure proper fit and function.
- Monitor Water Quality: If possible, use a water filter to remove impurities from tap water before using it in the humidifier preventing accumulation of minerals and impurities.
- Provide Sufficient Airflow: Ensure the room has adequate ventilation to maintain balanced humidity and avoid condensation.
Note: Implementing these preventive measures can help in maintaining the humidifier’s efficiency and preventing issues related to water spitting, ensuring a comfortable and healthy indoor environment.
FAQs About Humidifiers and Spitting Out Water
Is a Humidifier Supposed to Spit Out Water?
No, a humidifier is not supposed to spit out water. Spitting water can be a sign of issues such as overfilling, dirty or damaged components, or incorrect settings.
Addressing these issues promptly and maintaining the humidifier regularly can prevent water spitting.
Why is My Humidifier Gurgling?
A humidifier might gurgle due to the movement of water within the unit as it’s drawn from the tank to the humidifying element. This sound is normal in most cases.
However, excessive gurgling might indicate issues like low water levels, a dirty or clogged filter, or misalignment of components, which may require attention.
What Happens if You Put Too Much Water in a Humidifier?
Overfilling a humidifier can cause several problems, such as water spitting, leakage, and inefficient operation.
The excess water may be expelled along with the mist, leading to dampness around the unit. It’s important to fill the water tank only to the indicated maximum level to avoid these issues.
Is it Bad for a Humidifier to Run Out of Water?
Yes, allowing a humidifier to run out of water can be detrimental to the unit. It may cause the motor to overheat, potentially leading to damage.
Additionally, running a humidifier without water can cause unnecessary wear and tear on the unit, reducing its lifespan and efficiency.
Note: It’s essential to monitor the water level and refill the tank regularly to avoid running it dry.
How Do I Know if I Need to Replace My Humidifier?
Knowing when to replace a humidifier involves monitoring its performance and condition.
Indications that replacement may be necessary include:
- Consistent poor performance despite regular maintenance
- Presence of irreparable damage
- Persistent issues
- Unit is outdated and consumes excessive energy
Note: Replacing a faulty humidifier is crucial to maintaining a healthy and comfortable indoor environment.
Enjoy personalized, quiet comfort with this smart humidifier that adapts to your home’s needs, ensuring optimal moisture levels and relief from dry air.
Final Thoughts
Understanding why a humidifier is spitting out water is pivotal in maintaining a moisture-controlled environment, free from the unnecessary hassle of water damage and inconvenience.
By addressing issues like overfilling and ensuring regular cleaning of the humidifier components, users can mitigate the occurrence of water spitting, thus elongating the lifespan and efficacy of their humidifiers.
It is essential to monitor the device’s performance continually and undertake corrective measures promptly to maintain a healthy, comfortable living or working space.
