Some purifiers are enriched with specific filters supposed to eliminate Volatile Organic Compounds (VOCs), including the infamous formaldehyde.

Then there are all kinds of options, such as an automatic mode that adapts the speed of the purifier to the amount of pollution of the ambient air using sensors. Some purifiers also include options such as a programmer and sometimes a filter change indicator. Sadly, though a lot of these are not as advertised.

Several models have harmful components (like ozone) that clean the air, but harm you. Others do not even do the job at all.

Operation Of The Air Purifier

To effectively treat domestic pollution, the operating principle of the Winix 5500-2 air purifier has been specially designed to guarantee excellent performance. The air sucked by this air purifier will pass through a series of filters. These filters each have their own role and target specific pollutants.

All together in series they effectively neutralize many types of pollutants, and the air released by the air purifier is, therefore, a lot cleaner than when it went into the unit. This is why it is very important to pay close attention to the quality of the filters, because, the higher quality they are, the more they will effectively retain a large number of pollutants.

As opposed to the superior filters used by the Winix 5500-2, popular models like the Ionic Pro air purifier and the Envion Therapure air purifiers use ionization technology. These models work by releasing negative ions that are attached to the suspended air particles, which make them fall to the ground.

More pollution as you have to pick up these microscopic particles with a vacuum cleaner while cleaning your home. They also easily get ruffled and float around once more.

The Winix 5500-2 Filtration System In Detail

As mentioned above, the operation of the Winix 5500-2 air purifier is based on an air ventilation system combined with a series of filters. The polluted air starts by passing through a pre-filter that will capture the largest particles visible to the naked eye, including animal hair or large specks of dust.

Installed directly between the hood and the other filters, it makes sure not to let any macro-particle pass.

Then there is also a HEPA filter, originating from within the medical community, which will trap the smallest particles. Thanks to its particularly tight weaving design, this will retain all kinds of particles including mites, molds, bacteria, or fine particles, either physical or chemical. Attention, fineness, and quality of a HEPA filter vary according to its classification. Thanks to the True HEPA class of this purifier, it is effective at removing up to 99.97 percent of pollutants from your home.

The Different Types of Winix 5500-2 Filters

Here are details on each of the filters used. You will see why they are superior to most.

HEPA Filters

HEPA Filter, or High-Efficiency Filter for Air Particles, is a filter that incorporates a very tight weave to physically trap microparticles about 0.3 microns. Air Purifiers featuring this type of filter will be able to get rid of mites, which have a size of 10 to 25 microns, or pollens with a diameter of between 5 and 50 microns, bacteria, fine dust, etc.

These filters were initially designed for the medical use, and are now accessible to the general public through the Winix 5500-2.

Activated Carbon Filter

The active carbon air filter, meanwhile, contains granules of activated carbon powder and will act to absorb chemical compounds: gases, fumes, and bad smells. In other words, it acts as a chemical cleanser and deodorizer to give you a particularly clean atmosphere.

Surprisingly, the carbon filter of the Winix 5500-2 can simply be rinsed with water several times a year. It does not need replacement.

PlasmaWave Technology Permanent Filter

This technology charges the positive and negative ions in the air. When these ions bind to bacteria and virus, it destroys them by depriving them of hydrogen.

As opposed to ozone, this is a safe way to get rid of pet odors, and kitchen or tobacco odors. This is also the best way to get rid of mold.

Is it safe?

To give you an idea, it is certified safe by the California Air Quality Agency’s (CARB). These are the toughest guys in the world to get past, so you should be certain it is safe for you. In layman’s terms, its actual percentage of it being non-safe is less than 0.05 in one million.


This air purifier is for anyone who wants superior air quality in their home. And the Winix 5500-2 air purifier can be used for curative or preventive purposes. It is extremely useful for people with respiratory problems such as asthma or allergies but also for people who want to fight against pollution or bad odors.

Able to handle a good volume of air and room space, it is ideal for both home and office alike. Improve your comfort and remain safe, with this vital addition to your home.
