About Winix 5500-2 Air Purifier

The Winix 5500-2 is an air purifier with a True HEPA filter that is one of Winix’s most popular products. Winix provides home devices since 1973 long before the invention of HEPA, but as you can see, they’ve kept up with the times and built a True HEPA filter air purifier.

Winix offers a variety of versions in addition to the 5500-2.

The Winix 5500-2 has a simple black color scheme that makes it incredibly neutral in any setting, designed to fit in a medium-sized room. However, this Winix 5500-2 review will show you how it has a lot of fascinating capabilities and advanced features.


The 5500-2 is a high-quality air purifier with a very well-designed device. You can use this air purifier in any room due to its simple design and neutral colors.

The front panel, including each side, has air intake. The good news is that the air is released on top of the gadget once purified. This is useful because if you stand in front of it, air will not flow directly into you.

The control panel sits on top of the front panel and provides you with a wealth of options and complete control. A handle is located behind the control panel to make transporting it simpler. Because it is not heavy, Winix 5500-2 is easy to move.

Initial Operations – Winix 5500 2 Air Purifier Control Panel

Instead of a touch panel, the control panel has buttons. In other words, you’ll need to press a button; simply placing your finger on a button will not be enough. For some, this is a benefit, while others prefer touch panels.

However, the controls are simple to operate, and we’re confident that you will have no trouble controlling this air purifier.

All of the device’s lights will turn on for a few seconds, and a sound will be heard when there is electricity. You should now be able to use the air purifier.

Smart Sensor

A smart sensor is a cutting-edge piece of equipment that monitors air quality. The air quality indicator can switch lights based on pollution levels in the air, and auto mode can switch gears, thanks to this sensor.

Start-up and Filter Installation


You must install the filter prior to the first startup. The air purifier’s filters are enclosed in a removable plastic bag. If you don’t, you risk damaging the equipment.

Remove the air purifier from the power source before using it. Grasp the top of the front panel and slowly pull it forward to remove it. Once removed, you’ll notice a bag with filters. Remove the plastic bag and take them out.

You can now add filters with care. They must fit exactly and in the correct order inside. The True HEPA filter comes first, followed by the Carbon filter, and then the pre-filter. The pre-filter is the first to catch air.

How To Replace Winix 5500-2 Filters?

Replace the filters every 12 months on average. Since the Winix 5500-2 air purifier has a filter indicator, you’ll always know when it’s time to change the filters. Replacing the filter is as straightforward as setting up the system for the first time.

Open the front panel by holding it at the top and pulling it forward. To release the pre-filter, press the tabs towards the top. You can remove the AOC carbon filter and real HEPA filter.

Remove the new filter from its bag. Insert the True HEPA filter first, then the AOC carbon filter, and finally the pre-filter. Return the front panel to its original position and close the air purifier.


Step 1

To begin, switch off the power to the unit. Remove the front panel immediately by gripping its upper edge and gently dragging it forward.

Step 2

Press the tabs towards the top of the pre-filter to remove it, then pull out the old AOC Carbon and True HEPA filters.

Step 3 

To remove any undesired dust, vacuum the inside of the lid, the pre-filter, and the air inlet.

Step 4

Finally, remove the new filters from their protective plastic cover and place them into the device. The True HEPA filter is installed first, followed by the AOC Carbon filter.

Step 5

After changing the filters, turn on the unit and push the “Reset” button for 5 seconds using a thin object, such as a paper clip, to reset the filter reset indicator.

How Often Should Filters Be Replaced?

At the very least, the HEPA and carbon filters should be replaced once a year. Keep an eye on your filters if your environment is unusually dusty, since they may fill up quickly. There is a “check filter” light, but it is controlled by the time and duration since the last filter change, not by how dirty the filters are.

Is it Possible to Clean Filters?

The pre-filter is permanent (it does not need to be replaced) and should be washed at least once every two weeks. The carbon filter may be washed as well, and Winix suggests doing so every three months.

Cleaning the Filters

Simply clean them under warm water and let them air dry. There is no need to use any chemicals or detergents; water will suffice. The pre-filter can be vacuumed for a quick clean, but if it appears to be particularly dusty, rinse it with water.

Final Thoughts 


The Winix 5500-2 Air Purifier is a great addition to any home. It includes a sophisticated sensor for detecting contaminants in the air. The purifier also offers an auto mode that adjusts the fan speed automatically and a sleep option for silent night use.
