Why Is My Winix Air Purifier Blinking? Reasons & Solution

One of the most common reasons a Winix air purifier may start blinking is because the indicator on top tells you that it’s time to change or replace the air filter.

The blinking red lights are simply a reminder that it’s time to take care of your unit so it can continue to purify your air effectively.

If you don’t change the filter when needed, the purifier will start to work less efficiently and may eventually break down completely.

To avoid this, check your air filter regularly and replace it when necessary. Doing so will keep your Winix air purifier working like new for years to come.

Why Is My Winix Air Purifier Blinking

Why Is My Winix Air Purifier Blinking?

The red light on your Winix air purifier indicates that the unit’s sensors have detected a high level of air pollution. When this happens, it is important to let the air purifier run uninterrupted until the red light changes color.

Depending on the severity of the pollution, the light will change from red to Amber or Blue. If the pollution is severe, it may take some time for the light to change color.

It is important to keep the air purifier running until the pollution has been cleared and the light is no longer blinking.

Here, we are going to explain other reasons for a blinking red light:

Poor Air Quality

A blinking red light may also indicate poor air quality in your home. This could be due to a variety of factors, such as dust, pet dander, or other allergens.

If you notice that the red light is blinking more frequently, it is important to take steps to improve the air quality in your home. This may include vacuuming more often and dusting regularly.

Filters Need Proper Cleaning

Another reason why the red light on your Winix air purifier may be blinking is because the filters need to be cleaned or replaced.

If you notice that the light is blinking more frequently, it is a good idea to check the filters and clean them if necessary. If they are excessively dirty, they will need to be replaced.

To clean the filters, simply remove them from the unit and wash them with warm water and soap. Be sure to let them dry completely before putting them back in the air purifier.

It is also a good idea to check the filters regularly and replace them every few months to ensure they are always functioning properly.

Sensors Need to Clean

The sensors on your Winix air purifier may also need to be cleaned if the red light is blinking. To clean the sensors, simply use a soft brush to remove any dust or dirt that may have accumulated on them.

Winix Air Purifier Two Lights Blinking

Winix air purifiers are known for their effectiveness at removing pollutants from the air in a home or office. Like many other appliances, however, they can sometimes experience issues that cause them to behave unexpectedly.

One common issue with Winix air purifiers is when the two lights on the front of the unit start to blink simultaneously.

There are several potential reasons why the two lights on a Winix air purifier might start blinking. One of the most common reasons is that the air purifier’s filter needs to be changed.

Over time, the filters in an air purifier can become clogged with pollutants, reducing the unit’s ability to clean the air effectively. When this happens, the two lights on the front of the unit will start to blink to alert the user that the filter needs to be replaced.

Another potential reason for the two lights to start blinking is that the air purifier’s fan has stopped working properly. The fan is an essential component of an air purifier, as it is responsible for pulling in air and circulating it through the unit’s filters.

If the fan stops working, the air purifier will be unable to clean the air effectively, and the two lights on the front of the unit will start to blink.

In some cases, the two lights on a Winix air purifier might start blinking if the unit is experiencing an error or malfunction. This could be due to a problem with the air purifier’s internal components, such as the sensors or control board.

If this is the case, the best course of action is to contact the manufacturer for assistance.

It’s important to address any issues with a Winix air purifier promptly to ensure that the unit continues to function properly. If the two lights on the front of the unit start to blink, the first step is to check the air purifier’s filters and replace them if necessary.

If the filters are in good condition, it’s worth trying to reset the unit by unplugging it and then plugging it back in. If the problem persists, contact the manufacturer for assistance.
