The primary purpose of an air purifier is to effectively remove airborne pollutants and improve the quality of the air you breathe. In this regard, the Winix 5500-2 excels.

The True HEPA filter efficiently captures microscopic particles, such as dust, pollen, and pet dander, providing relief for individuals with allergies or respiratory issues.

The activated carbon filter effectively reduces odors, smoke, and volatile organic compounds (VOCs) commonly found in household environments.

The PlasmaWave technology is a notable addition to the air purification process. It works by creating positive and negative ions that combine with water vapor in the air, producing hydroxyls.

These hydroxyls neutralize harmful pollutants, such as bacteria, viruses, and chemical vapors, without emitting any ozone.

The combination of the True HEPA filter, activated carbon filter, and PlasmaWave technology ensure that the Winix 5500-2 provides thorough and efficient air purification for your living space.
