Plasmawave Air Cleaner Reviews
Plasmawave air cleaner by Winix is one of the most modern air cleaners in today's market. Made by Winix (a Korean electronic corporation), this air purifier has risen fast to join the rank of premium air cleaner intended for medium-sized rooms (300 sq. feet or less). You can be assured that its quality and price is comparable to the long time leader of premium smaller room air purifier, Austin Air Healthmate Jr and Blueair 201.
But what makes Plasmawave air cleaner special ?
These air purifiers are special because not only they have the standard filtration stages (prefilter for coarse particles, HEPA filter for fine particles and carbon filter for gas absorption), but they also utilize Nano Silver mesh to ensure destruction of germs as well as the optional plasma wave technology.
The Technology Behind Plasma Wave Air Cleaner
Each Plasma Wave air cleaner model (except 5000B) has a 5-stage filtration system:
Plasma Wave Technology - A Review
Plasmawave is a technology which partially charges air such that the air is turning from the gas state into plasma state.In the plasma state, air becomes both positively and negatively ionized and, in the presence of water vapor from the air, can turn into hydroxyl radicals. Hydroxyl radicals, like ozone, are unstable and highly reactive. These reactive radicals readily attack volatile organic gases, viruses, bacteria and other gases; either killing them or changing the chemicals into harmless air molecules. After the reaction takes place, the hydroxyl itself changes into water molecules.
Hydroxyl radical is often touted as the nature's detergent and functions as the sink of many volatile organic gases in our air. Ozone, to some extent, does the same too. However, unlike ozone, hydroxyl radicals have a very short life, around 2-5 seconds, whereas ozone, while many claim to have the life span of 30-60 minutes, in reality often lingers for much longer than that. In addition, ozone can irritate the respiratory system, especially in people with existing respiratory disease. This makes ozone generator, or ozone air purifier unsafe for home use. This also applies to ionic air purifiers which produce ozone continually as the by-product.
So, if you are looking for an ionic air purifier, rather than buying an air ionizer, which merely negatively-charges air particles, it's better to buy the ones with plasma technology which indirectly produces hydroxyl radicals. For your information, air ionizers basically work by negatively charging air particles, so then the suspended air particles can eventually fall down to the floor to be vacuumed. However, this method has its flaws, especially if not used in conjuction with other air filtration technologies:
With the hydroxyl radical production technology employed by the Plasmawave air cleaner, the suspended air particles are changed to other forms of chemicals permanently, rendering them harmless. In addition, the hydroxyl radicals are also capable of killing microorganism in the air.
The other positive thing about this technology is that it employs an active approach in cleaning up all ultrafine particles. Instead of waiting for the ultrafine particles to be suspended in the air and enter the machine, the machine produces hydroxyl radicals indirectly which go out and react with any particles in the air. It is also proven to be pretty powerful in attacking air particles which stick to furniture, carpet, and so forth.
There's one potential drawback on this kind of technology though. Since hydroxyl radicals are very reactive, it's best to switch on the plasmawave mode when there is nobody in the room. This is because they can potentially irritate your eyes and nose lining if you are happen to be sensitive.
Think about it.
These radicals are aggressive in attacking bacterial cells. Human beings are made from cells, so these radicals can attack the most sensitive outer cells in our body, especially our eyes and nose lining. In this respect, a plasmawave air cleaner is less safe than the 'ole' air ionizer. But it is definitely safer than using air purifiers which produce ozone as the main cleaning agent. And is more efficient than both air ionizer and ozone generator in cleaning up the gases, odor, smoke and germs.
Other Strong Feature of Plasmawave Air Cleaner
In common with other Asian-based air purifier, this air purifier not only delivers clean air, but it also loads the machine with modern conveniences.

Winix Plasmawave Air Cleaner Models
Winix Plasmawave air purifier is currently available in 2 series, the 5000 and 9000 series. Each series has at least 2 models to choose from:
All Winix Plasmawave air cleaner, except the 5000B model, are suitable for people with mild to moderate allergies,and those with asthma. They are also good for people who wants to address mild odor problems, but it might not work well if used in an environment when there's a continuous cigarette smoking or pet since these air purifiers, even with the plasmawave option, are not particularly strong in curbing out gases.
