The air purifier has a built-in pre-filter. The pollutants with large sizes are captured at this stage. They include pet dander and skin. The prefilter is also combined with an Activated carbon filter that eliminates any bad odors from smoke, pet dander and other household chemicals.

True HEPA filter

This filter captures 99.97% of all the pollutants in the air. It can capture small size pollutants as small as 0.3 microns.

Winix PlasmaWave

This is a type of ionizer that is included in the air purifier. It’s necessary to improve the performance of the HEPA filter. This is done since the HEPA air purifiers have less maximum air coverage.  Adding the Winix PlasmaWave reduces the number of pollutants even more. You choose to use it or not as there is a switch to turn it on or off.

Most Winix air purifiers have the PlasmaWave technology, and as highlighted above, the combination with HEPA filters provides effective air filtration. Unlike many ionizers, PlasmaWave technology emits both positive and negative ions. Ordinary ionizers emit negative ions only to attract the pollutants in something similar to a collector plate. The negative and positive ions emitted by the plasmawave technology form hydroxyls that attack the pollutants in the air.

There is always a concern about the ozone emitted by the ionizer, nevertheless, every air purifier has to be certified by the CABR for its use in California. In this case, Winix C535 has been certified as being ozone free and can be safely used in the homes. The low levels of ozone it emits have been tested and approved to be safe for human health.
