Winix PlasmaWave Series WAC5500 Review

The Winix PlasmaWave Series WAC5500 is an efficient ion based air purifier that removes dust, pollen, allergens and other indoor pollutants from your house, allowing you to breathe clean and fresh air. It uses an ionizer to electrically charge small particles of dust and makes it easier for the filter to absorb them.


This air purification system is effective and removes many indoor pollutants, like dust, allergens, hair and bad odors. It eliminates pollutants at a molecular level to neutralize bacteria, viruses, chemical vapors, and odors without harming the environment. However, the fact that it uses ions in the functioning process may be harmful to your lungs because free-floating charged particles may affect sensitive lungs. A shortcoming of the air purifier is that it is loud when set at its highest capacity, which makes it hardly suitable for bedrooms, nurseries, and other quiet areas. It is an Energy Star qualified appliance that helps you save money in the long run.

This air purifier is equipped with a filter monitor that lets you know when to replace the filters.
The fans are adjusted by an air-quality sensor that estimates how many pollutants are in the air when the machine is set in auto mode. It starts the purification process by pulling the air through a carbon pre-filter which removes large particles, like hair, and reduces bad odors. After that, the HEPA filter captures the smaller particles like dust and allergens and the ionizer charges particles as they leave the air purifier so that they will be able to attract other particles, making them larger and easier to capture the next time they pass through the filters.

Ease of use

The Winix PlasmaWave Series WAC5500 comes with a one-year warranty against damages, which is a shorter warranty than in other purifiers, while the Smart Sensor with Auto-Mode adjusts your air cleaner settings automatically to adapt to the needs of your environment, which makes it very easy to use. The air purifier comes with a washable HEPA filter and the filter monitor lets you know when the filters need to be changed, which is a great advantage of the device. It is very easy to use thanks to the remote control it comes with. However, a big flaw is represented by the lack of an operation schedule that would allow you to set the device to work at a certain time, and of the sleeping mode feature that forces you to monitor the device and change its settings if you do not want it to run continuously.

Final Thoughts

What adds to the magnificent performance of this model is the fact that it features the PlasmaWave technology as well, a technology that ensures pollutants like viruses, germs, and bacteria will be completely removed from the air by attacking them at a molecular level. Therefore, the Winix PlasmaWave Series WAC5500 air purifier is an amazing choice to go with if you or any of your loved ones suffer from allergies or asthma, allowing you to breathe the air indoors without fearing that it might harm your health in any way. If this is not enough to convince you that you should invest in this model, know that it is Energy Star certified for its low operational costs, so it won’t consume much at all despite the fact that it boasts an amazing performance.

    I have this air purifier in my home for more than 3 months. What I can say about it is that it’s incredibly good at its job, eliminating unpleasant odors and leaving the air a lot cleaner than before. On the downside, it does indeed tend to make a lot of noise when it’s on the high speed setting, this being the reason why I avoid to use it in the bedroom during the night.

    If you get passed the bulky design, it’s actually a decent air cleansing appliance. I have it in my office and I’m very pleased with the air quality since I’ve been using it. Of course, it doesn’t hurt that it actually consumes little energy as I haven’t actually seen a big spike in the bills, which is perfect considering the fact that I spend about 9-10 hours in the office daily with the purifier turned on.

  • Caroline

    Does it come with a timer feature or not?

    • Unfortunately, it does not feature a timer, so you cannot set the duration of its operation as you like and have it automatically turn off when the time passes, but rather turn it off manually when you want to.
