2. Winix 5500-2 Air Purification Stages

Winix 5500-2 Air Purification Stages

I. True HEPA Filter

The True HEPA filter also referred to as High-efficiency Particulate Arrestance filter traps almost 99.97% of the dust particles and other contaminants present in the air. Compared to HEPA type filters, these have a higher standard of filtration that is universal for all filters categorized in this grade. Also, it captures dust mites, pet dander and other allergens as small as 0.3 microns. The holes in a HEPA filter are so small that they can get easily clogged by large dust particles pulled in by the air purifier’s fan. Also, it can’t be washed and therefore, in order to run it efficiently, you would require a pre-filter.

II. Washable Carbon Filter

Activated Carbon filter, or charcoal filter, is a bed of activated carbon normally in granular or powdered square structure and comprises of a huge number of minor permeable pores. This air filter has been integrated to be extremely porous and this is the famous filtration against gases, synthetics and Volatile Organic Compounds (VOCs). In any case, the Activated Carbon filter can’t evacuate fine particles like residue, dust parasites, pet dander or dust from the air. In air purifiers, this is generally utilized in concurrence with the HEPA filter to capture huge air contaminants and to diminish undesirable odors and smoke. Lastly, unlike other popular air purifiers, the odor filter in this one is washable. This reduces your upkeep costs considerably, as you would only need to replace the HEPA filters upon indication from the machine. There are multiple other air purifiers with reusable filters that you could consider if recurring filter replacement costs are of concern to you.

III. Plasmawave Filter

The PlasmaWave is the center air filtration of any Winix air purifier, and this innovation is viable against a wide range of airborne contaminants. PlasmaWave, in contrast to different ionizers, utilizes the power to make both negative and positive particles. In Winix air purifiers, the procedure of PlasmaWave places the air in a plasma state and strikes the water fume to discharge the hydrogen and oxygen from their sub-atomic bond. 

The hydrogen and oxygen are present in the state to form alliances and as a result, they frame hydroxyl radicals (OH). The hydroxyl radicals are flimsy particles looking for harmony by taking atom from the neighbor molecules, accordingly decimating them simultaneously. 

What’s more, the neighboring particles, they are surely the airborne contaminations that incorporate infections, microscopic organisms, germs, scents, concoction gases and Volatile Organic Compounds. The hydroxyl radicals destroy these pollutants to form harmless molecules such as water, oxygen, hydrogen and carbon dioxide. 

Additionally, Winix guaranteed that there is no ozone discharge during the entire procedure of PlasmaWave and this ion generator can be turned off separately too.

CADR generally stands for the clean air delivery rate. It calculates how many cubic feet of air the purifier can filter per minute and lets you identify how fast your air purifier functions. The CADR rating is directly proportional to the air purification system, which implies that Higher the CADR number, better is the air filtration. The CADR of Winix 5500-2 is 243 Dust, 232 Smoke and 246 Pollen. While CADR isn’t a highly reliable factor for comparison, it may give you a rough estimate of the air cleaner’s capabilities.
