However, there may be times when you need to reset your Carrier air purifier to resolve any issues or after completing regular maintenance.

In this article, we'll guide you through the process of resetting your Carrier air purifier so you can confidently handle any situation that may arise.

Why Might You Need to Reset Your Carrier Air Purifier?

You might need to reset your Carrier air purifier for a few reasons. We've shared some below.

Filter Replacement

When you replace the filter in your Carrier Air Purifier, it's essential to reset the filter replacement indicator.

The indicator helps you keep track of the filter's lifespan, ensuring that the air purifier operates effectively.

A reset tells the unit that a new filter has been installed, allowing it to accurately monitor its condition and alert you when the next replacement is due.

System Malfunction

There could be times when your Carrier Air Purifier displays a "System Malfunction" message.

Resetting the air purifier in such instances can often help to clear the error and restore regular operation. By resetting the air purifier, you're giving it a fresh start to operate correctly.

If the "System Malfunction" message persists post-reset, it's advisable to consult the user manual or contact Carrier customer support for further assistance.


During maintenance, you might discover that a reset is required to optimize the cleaner's performance.

For instance, if a filter becomes dislodged, re-seating and resetting the unit can help it recognize the filter and operate efficiently.

Additionally, after cleaning the pre-filter, a reset might be beneficial to recalibrate the unit’s performance metrics.

Where Can You Locate the 'Reset' Button on the Carrier Air Purifier?

You might have stumbled upon various sites suggesting that the reset button on your Carrier Air Purifier can be accessed through the control panel.

However, upon thorough investigation, it's apparent that Carrier does not designate a specific reset button on their models.

Instead, to reset your air purifier, you'll typically need to depress the power switch or simply turn it off and on.

Doing so can serve as a reset, aiding in refreshing the system and ensuring it operates efficiently after a replacement or when the system malfunctions.

Your Carrier Air Purifier is crafted to improve your indoor air quality. However, like any appliance, it may face some issues over time.

Here are common problems and how to address them:

Clogged Filter

A common issue that can reduce the effectiveness of your air purifier is a clogged filter. It's essential to inspect the filter for dirt and debris regularly.

Dislodged Filter

A dislodged filter can adversely affect the performance of your air purifier by allowing unfiltered air to bypass the filter.

Ensure the filter is properly seated and secured in place. If the filter is dislodged, re-seat it properly, ensuring it fits snugly within its housing.

Power Cord Failure

A damaged or loose power cord can interrupt the power supply to your air purifier, preventing it from operating.

Inspect the power cord for visible damage and ensure it's securely plugged into the air purifier and the electrical outlet.

A secure connection will maintain a steady power supply, ensuring continuous operation of your air purifier.

If you notice any damage to the power cord, it's advisable to replace it to prevent any potential hazards.

Remember, it's always advisable to consult the user manual or contact Carrier customer support for the most accurate information and guidance.
