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.

How to Fix the Winix Air Purifier Red Light: A Step-by-Step Guide

Air purifiers are essential in maintaining a clean and healthy indoor environment. They work by filtering out airborne particles and contaminants that can cause respiratory problems and other health issues.

However, just like any other appliance, air purifiers require regular maintenance to ensure that they are functioning properly.

One of the most common issues that people face with their air purifiers is the blinking red light. This indicates that the filters need to be cleaned or replaced. Here’s a step-by-step guide on how to fix the Winix air purifier red light.

Step 1: Turn off the air purifier and unplug it from the socket.

Before you start cleaning or replacing the filters, make sure to turn off the air purifier and unplug it from the power source. This will ensure that you don’t accidentally damage the appliance or injure yourself.

Step 2: Remove the front panel from the air purifier.

Locate the front panel of the air purifier and remove it. The front panel is usually secured in place with clips or screws. You may need to refer to the user manual to locate the clips or screws.

Step 3: Remove the filters.

Once the front panel is removed, you will be able to access the filters. There are typically two types of filters in a Winix air purifier: a pre-filter and a True HEPA filter.

The pre-filter is usually located at the front of the unit and can be removed by pushing the tabs at the top. The True HEPA filter is located behind the pre-filter and can be removed by pulling it out.

Step 4: Replace the filters.

If the filters are dirty or damaged, they will need to be replaced. Make sure to purchase the correct replacement filters for your specific model of air purifier. To replace the filters, simply insert the new filters in the same way that you removed the old ones.

Step 5: Clean the pre-filter (if necessary).

If the pre-filter is dirty, it will need to be cleaned. You can do this by vacuuming it or washing it with soap and water. Make sure to dry the filter completely before reinserting it into the air purifier.

Step 6: Reset the air purifier.

After replacing or cleaning the filters, it’s important to reset the air purifier. This will ensure that the red light goes off and that the air purifier is functioning properly.

To reset the air purifier, locate the reset button (usually a small hole next to the red light) and press it for 5 seconds using a paper clip or other small object.

Tips for Replacing the Filters Correctly

Replacing the filters in your air purifier is a simple task, but it’s important to do it correctly to ensure that the air purifier is functioning properly. Here are some tips to keep in mind when replacing the filters:

Make sure to purchase the correct replacement filters for your specific model of air purifier.
Follow the manufacturer’s instructions for replacing the filters.

When inserting the True HEPA filter, make sure to align the arrows on the filter with the arrows on the air purifier. Always reset the air purifier after replacing the filters.

Importance of Resetting the Air Purifier

Resetting the air purifier after replacing the filters is crucial to ensure that the appliance is functioning properly. If you don’t reset the air purifier, the red light will continue to blink, indicating that the filters need to be replaced or cleaned, even if you’ve already done so.

By resetting the air purifier, you are essentially telling it that new filters have been inserted and that it should start fresh.

How to Reset Your Winix Air Purifier

If you have a Winix air purifier, you may have noticed that sometimes the red light flashes even after you’ve replaced the filters. This can be a bit frustrating, but fortunately, there’s an easy fix. All you need to do is reset the air purifier, and it will recognize the new filters.

To reset your Winix air purifier, follow these simple steps:

  • Unplug the air purifier from the power outlet.
  • Locate the reset button. It’s a small hole next to the red flashing light.
  • Take an elongated and thin object, such as a paper clip, and insert it into the hole.
  • Press and hold the button for about 5 seconds.
  • Release the button and plug the air purifier back in.
  • Once you’ve completed these steps, the red light should stop flashing, indicating that
  • the air purifier has recognized the new filters. If the light continues to flash, there may be an issue with the pre-filter.

Cleaning the Pre-Filter Thoroughly to Prevent Blockages

The pre-filter on your Winix air purifier is an important component that helps to trap larger particles before they reach the HEPA filter. Over time, the pre-filter can become clogged with dust and other debris, which can reduce its effectiveness and even cause blockages.

To clean the pre-filter on your Winix air purifier, follow these steps:

  • Turn off the air purifier and unplug it from the power outlet.
  • Remove the front panel from the air purifier.
  • Locate the pre-filter, which is the first filter in the air purifier.
  • Gently remove the pre-filter by pulling it out from the tabs at the top.
  • Use a vacuum or a soft brush to remove any dust or debris from the pre-filter.
  • If the pre-filter is particularly dirty, you may want to wash it with warm water and mild soap.
  • Allow the pre-filter to dry completely before reinserting it into the air purifier.
  • Reattach the front panel and plug the air purifier back in.
  • By cleaning the pre-filter regularly, you can help to prevent blockages and ensure that your Winix air purifier continues to operate effectively. It’s recommended that you clean the pre-filter every 2-4 weeks, depending on the amount of use the air purifier receives.
