Winix 5500-2 Review

Winix 5500-2

Air Purifier


The Winix 5500-2 is one of the best air purifiers to come from the Korean company Winix. It comes with a great design.

The filter has a plastic body and is available in a luxurious black color.

This sets it apart from the previous generation Winix 5300-2.

Given that air purifiers have to be kept plugged in all day for best results, it’s better to make them from plastic rather than metal. Don’t worry about the build quality though. Winix choose the best materials and the best manufacturing process for the job.

Winix 5500-2 Design

The front of the filter features five function buttons. These buttons are much easier to press than with the previous Winix WAC9500.

The Winix also comes with an LED smart sensor that has three different colors.
The different colors correspond to different levels of air quality, so the light lets you know what the quality of air is like in the room at the time.
There is also an intake grill on the front of the filter. This is where the air passes through ready to be filtered.

Winix 5500-2 Filters

Winix always uses the latest technology with their products and the 5500-2 is no exception. The filter uses a 4-stage air purification process that combines all of the best of Winix technology to keep the air in your home clean. Sadly, it doesn’t have the same range of filters as the Winix WAC9500, but you can still expect a pre-filter, a true HEPA filter, and the Winix PlasmaWave filter.


The pre-filter helps to capture large contaminant particles including pet dander, pet hair, pollen, and dust. This pre-filter can be removed and washed and reused for quite some time.

Activated Carbon Filter
The Washable Advanced Odor Control (AOCTM) Carbon Filter carbon remove odors as well as protect against VOCs. 

True HEPA Filter 
As mentioned before, a true HEPA filter captures 99.97% of all particles down to 0.3 microns. This includes allergens, pollen, mold, virus particles, and fungi particles, and dust. They also help with odors including smoke odors, mold odors, and the smells of cooking. The true HEPA filter can’t be washed and has to be replaced on a regular basis.

Winix PlasmaWave

The PlasmaWave is a kind of ionizer. Ionizers improve the effectiveness of these filters and eliminates more contaminants. It can be turned off and on as you need it.

Winix 5500-2 Extra Features

The Winix 5500-2 has been around for a while now so there’s not much in the way of extra features. Similar to other air filters from the Winix brand, it comes with a great Smart Sensor that detects the current air quality. This feature adjusts the fan speed according to real-time data on air quality to save energy. Running a filter all the time is great for your allergies, but not so much for your energy bills.

The air purifier also comes with a remote control for ease of use. It’s not a massive feature, but it’s sure to be appreciated by some users. 
It also comes with an LED life indicator that tracks the air filter health. 

It alerts you to when it is time to get a new filter for the purifier
