How To Set Up A Winix Air Purifier

Once you choose the right location to place the Winix air purifier in your home, you’ll need to set it up. This is very easy to do.

Start by installing the filters. Your Winix will have 3 filters that need to be installed (True HEPA, deodorization, and pre-filter). You will need to remove the front panel of the air purifier to install the filters.

Once the filters are installed, you will need to plug the air filter in. Press the “Power” button to turn the purifiers on and allow it 30 seconds to cycle and detect the air quality in the room.

Once it works through this cycle, you can set the purifier to auto or manual mode to your liking.

How To Reset Filter Light On Winix Air Purifier 

When the filter light comes on, it’s time to replace your filter. Once you replace your filter, you may need to reset the filter light in order for it to go off.

To do this, you will need to press down on the reset button and hold for at least 5 seconds. You will need a thin pointy object, like a bobby pin or paper clip, to hold down on the reset button.

What Do The Colors Mean On My Winix Air Purifier?

One of the features that sets Winix apart from other air purifiers is that they will let you know what the air quality is like in your room, so you have a better idea of what you’re breathing in.

The Winix air purifier lets you know the air quality by using different light colors.

Color-coded LED lights are used in the Winix air purifier as the air quality indicator. This is what each color of light means about the air in your room:

  • Blue- Good
  • Amber/ Yellow- Fair (Not bad, but could be a lot better)
  • Red- Poor

Is Winix PlasmaWave Safe?

Many airborne contaminants in the air could be harmful to your immune system, and Winix PlasmaWave used some of the safest technology to neutralize them.

This air purifier can work its magic while emitting very low levels of ozone. That’s why it’s considered one of the safest and most effective air purifiers on the market. 

Winix air purifier is one f the safest ways to limit airborne contaminants, such as:

  • Smoke
  • Pollutants
  • Dust particles
  • Pet dander
  • Mold
  • Viruses
  • Bacteria

     Winix Air Purifier Keeps Shutting Off

    Always check that your Winiz air purifier is securely plugged into the outlet. If it has been loosely plugged in, it may shut itself off.

    Once you check that, you should also confirm that you mistakenly didn’t set the air purifier to sleep mode. It’s very common for people to accidentally put their air purifiers in sleep mode when using the “Mode” function.

    In this situation, you only need to press Mode again to get out of it.

    When you press Mode, you can switch between different settings, such as low, medium, high, auto, and sleep.

    Set it back to auto or your desired strength.

    How Do I Clean My Winix Air Sensor?

    Once your Winix air purifier cleans your indoor air, it’s bound to get a bit gunked up. You must remove the front panel and filter to get the sensor cleaned.

    We recommend using a vacuum or a soft brush to remove any dust and dander that has built up on the sensor.

    You should also remove the pre-filter and rinse it under hot water to thoroughly clean it. Only use warm water, and never use soap, detergent, or other types of cleaner on the pre-filter.

    Always allow it at least 24 hours to dry before putting it back on your Winix air purifier.

    Winix Air Purifier Won’t Turn On?

    Always check the power cord first if the Winix air purifier is not turning on. Ensure it is not loose and securely connected to a power outlet. You should also ensure the outlet it is plugged into works properly.

    The main reason why a Winix air purifier won’t turn on is because of the power rating.

    >This rating is how much electricity is needed to operate the air purifier. When you determine the power outlet of the air purifier, make sure it is plugged into an outlet that is capable of providing that amount of power.

    For this reason, you should avoid using power bars and extension cords to provide power to your Winix air purifier.

    Winix Keeps Going Into Sleep Mode

    While the Winix air purifier is one of the most efficient air purifiers available, it can be very frustrating for users when it gets stuck in sleep mode.

    >If this happens to you, power off your air purifier and unplug it from the outlet. Wait for a few minutes before plugging it back into the wall.

    When you turn the air purifier back on, allow it to stay in sleep mode for at least 5 minutes. You should then be able to set it to a different mode.

    Winix C545 Fan Not Working

    If the C545 fan is not working, it is likely that you need to replace the filters. When your Winix air purifier’s filters get clogged up, it prevents the fan from working at full strength.

    >If the dirty filters are left in the device, they could lead to the 545 fans not working. 

    When clean filters are put back into the air purifier, the C545 fan should begin to work again. 

    Winix Air Purifier Two Lights Blinking

    If you notice two lights blinking on your Winix air purifier, this is not a good sign. The unit is malfunctioning, and you will be unable to troubleshoot this problem.

    >In this event, you must return the air purifier to the manufacturer and find out about a warranty replacement.

    How Does Winix Measure Air Quality?

    Winix has smart technology that can detect particles and other volatile organic compounds in the air using sensors.

    There is an AQI in the air purifier that will be able to scale the air quality in a detected range. When you set the air purifier to a specific setting, the fan will correlate to create good-quality air.

    >However, when the Winix air purifier is in auto mode, the fans will adjust themselves according to the AQI’s air quality reading. 

    Winix Air Quality Indicator Stays Blue

    This is a good sign if the indicator on your Winix air quality stays blue. It means the air inside the air purifier is good quality.

    Ideally, you want the indicator on your Winix air quality to stay blue. If you live in a smoke-free home and keep it clean, you may not have trouble keeping the light blue.

    If the indicator on your Winix air purifier stays red, you should replace the air filters as soon as possible. After changing the filters, reset the air purifier.

    Hold the reset button down for 5 seconds until you hear a beep. This should turn the red light off.

    If it doesn’t work, you may need to unplug the air purifier for a few minutes, plug it back in, and try the reset button again.

    2 class="wp-block-heading">Winix Error Code 02

    The Winix error code 02 is something you likely won’t come across with the Winix air purifier.

    The new technology uses color LED lights to let you know when something is wrong with the air quality or the filters need to be changed.
