Your dyson air purifier’s screaming secret: why it’s making that high-pitched noise

If your Dyson air purifier has suddenly started emitting a high-pitched squeal or whine, you’re not alone. This common issue can be frustrating, especially when trying to maintain a peaceful indoor environment. In this comprehensive guide, we’ll delve into the potential causes of this high-pitched noise and provide practical solutions to restore your purifier’s harmonious operation.

Why Is My Dyson Air Purifier Making High-Pitched Noise?

The high-pitched noise emanating from your Dyson air purifier can be attributed to several factors:

1. Dirty Filter

Over time, dust and debris can accumulate on the air purifier’s filter, restricting airflow and causing the motor to work harder. This increased strain can result in a high-pitched whining sound.

2. Misaligned Filter

If the filter is not properly inserted or misaligned, it can create gaps that allow air to bypass the filter. This can also put additional strain on the motor, leading to high-pitched noise.

3. Blockages in Airflow Path

Any obstructions in the air purifier’s airflow path, such as dust buildup or foreign objects, can hinder the smooth flow of air. This resistance can also cause the motor to work harder and produce a high-pitched noise.

4. Worn Motor Bearings

With prolonged use, the motor bearings in your air purifier can become worn or damaged. This can result in friction and a high-pitched squealing sound.

5. Faulty Motor

In rare cases, the motor itself may be faulty or malfunctioning. This can cause the motor to vibrate excessively, producing a high-pitched noise.

Troubleshooting and Solutions

1. Clean or Replace the Filter

Regularly cleaning or replacing your air purifier‘s filter is crucial for optimal performance and noise reduction. Follow the manufacturer’s instructions for cleaning or replacing the filter.

2. Check for Misalignment

Ensure that the filter is properly inserted and aligned in the air purifier. Any gaps or misalignments should be corrected to prevent airflow bypass.

3. Clear Blockages

Inspect the air purifier‘s airflow path for any blockages. Remove any dust buildup or foreign objects that may be obstructing the flow of air.

4. Lubricate Motor Bearings (Optional)

If the high-pitched noise persists after cleaning or replacing the filter, you can try lubricating the motor bearings. Use a few drops of light machine oil or silicone spray on the bearings.

5. Contact Dyson Support

If the above solutions do not resolve the high-pitched noise, it is recommended to contact Dyson support. They can provide further troubleshooting assistance or arrange for repair or replacement if necessary.

Preventing High-Pitched Noise

To prevent the recurrence of high-pitched noise from your Dyson air purifier, follow these preventive measures:

• Regularly clean or replace the air purifier’s filter.
• Check for misalignment and correct it promptly.
• Remove any blockages in the airflow path.
• Avoid placing the air purifier on uneven surfaces or near walls or furniture that may obstruct airflow.
• Use the air purifier in a well-ventilated area.
