Features of Winix 5500-2 Air Purifier

PlasmaWave Technology

One of the unique features of the Winix 5500-2 is its PlasmaWave Technology.

This technology helps to break down pollutants and allergens at the molecular level, making them easier to filter out of the air.

The PlasmaWave Technology creates positive and negative ions that combine with water vapor to form hydroxyls, neutralizing viruses, bacteria, and other pollutants.

True HEPA Filter

The Winix 5500-2 also features a True HEPA Filter, which captures 99.97% of airborne particles as small as 0.3 microns.

This includes dust mites, pet dander, pollen, and other allergens that can trigger asthma and allergies.

The HEPA filter removes these particles from the air, leaving you with cleaner and fresher air to breathe.

Advanced Odor Control (AOC) Carbon Filter

The Winix 5500-2 also has an Advanced Odor Control (AOC) Carbon Filter, which helps to remove odors from cooking, pets, and smoke.

It is made up of activated carbon pellets that absorb odors and volatile organic compounds (VOCs) from the air.

This filter is washable, so you can reuse it multiple times before needing to replace it!

Thanks to its PlasmaWave® Technology feature, Winix 5500-2 helps improve the air quality in your home!

This technology works by creating positive and negative ions that attach to airborne particles, such as dust, pollen, and pet dander.

It causes the particles to become heavier and fall to the ground, where they can be easily vacuumed or swept away.

We already mentioned its True HEPA filter that captures airborne allergens, including pollen, dust, smoke, and other ultrafine particles.

This means that the air you breathe will be cleaner and healthier!

This filter captures odors and neutralizes them, leaving your home smelling fresh and clean.

In addition to these benefits, the Winix 5500-2 is also easy to use and maintain.

It has a user-friendly interface and comes with a remote control for convenient operation.

The filters are easy to replace, and the air purifier has a filter replacement indicator to let you know when it’s time to change the filters.

Winix 5500-2 Air Purifier Pros and Cons

Before you make a decision, let’s take a look at the pros and cons of this popular air purifier.


  • Four-Stage Filtration: The Winix 5500-2 has a four-stage filtration system that includes a washable pre-filter, a True HEPA filter, a carbon filter, and PlasmaWave technology. This means it can capture 99.97% of particles as small as 0.3 microns, including allergens, pet dander, and dust.
  • Quiet Operation: This air purifier features a sleep mode that operates at a noise level of 27.8 decibels, which is quieter than a whisper. This makes it perfect for use in bedrooms or other areas needing a peaceful environment.
  • Smart Sensors: The Winix 5500-2 has a smart sensor that detects the air quality in the room and adjusts the fan speed accordingly. This means you don’t have to worry about manually adjusting the settings.
