To start with, the carbon pre-filter reduces household odors from pets, cooking, and smoke to mention a few. The True HEPA filter captures a wide variety of airborne particles including mold spores, pollen, dust, microbes, smoke, pet dander, et cetera.

This filtration mechanism is capable of capturing airborne contaminants that are small as 0.3 microns. The Plasmawave technology works by neutralizing various allergens and irritants including odors, chemical vapors, allergens, et cetera. This technology breaks down these pollutants at molecular level to create harmless byproducts.

According to Winix, the CADR values of this AHAM certified unit are: 251 for pollen, 216 for dust, and 235 for tobacco smoke.

Does the unit allow a user to monitor the quality of the air in a room? Yes, the WAC5500 has smart sensors that help you to monitor the air around you. In auto mode, the unit checks the air quality condition on a scale of 1-5 and changes the setting of the fan to a suitable speed.

In case you want to adjust the speed of your air purifier manually, the unit allows you to set it to Low, Medium, High, or Turbo. Furthermore, the WAC5500 has an alert system that notifies the user to replace a worn out filter.

Like most air purifiers, this unit produces a loud sound. The loudness depends on your settings and the sound is loudest when the unit is in the Turbo mode. When the unit is running on the lowest speed, you can hardly notice the sound. This unit is quieter than most air purifiers of same or lower capacity. For instance, we compared it with the WAC5300 and noted that there is a significant difference in the amount of noises that the two produce.

Users' feedback

Users quotes on Amazon.comA little noisy but the air quality sensor works well. Farting across the room sets it into turbo mode within 15 seconds and it clears the fumes quickly and efficiently. I purchased four units for the entire house and air quality is noticeably better. I no longer wake up with my nose stuffy and it has helped my postnasal drip during allergy season. I installed a pre-filter and it has extended the life of the filters...will need to be vacuumed every 3 months or so. I'm very happy with my purchase overall."

Users quotes on Amazon.comGreat product! We did a lot of research and comparing products. Absolutely pleased!"
