Needlepoint and Plate Ionization
Also known as Electrostatic Precipitators, these have been used by emissions of particulates. They operate by electrically charging a field between conductive plates. Incoming particles are given a charge opposite of the charge on the collector plates where they accumulate.
When high voltage is applied to a conductive surface that is not grounded, electrons will build up until they find a place to "jump off." A sharply pointed surface, such as a needlepoint, allows the negative ions to easily escape and ionize the air surrounding the point. Negative ions travel through the air until they attract airborne particulates that agglomerate until they are too heavy and settle to the floor
Units that use only negative ions as an air cleaning method are limited in their effectiveness. Negative ions, while beneficial, are not as powerful as other ions, such as hydroxyl ions and hydro peroxide ions, that can destroy viruses, bacteria and germs and chemicals, nor are they as effective at eliminate odors, unless there is an element of ozone created as a by-product of the ionization creation.
We carry two brands that produce negative ions. Surround used Needlepoint Ionization and Air Oasis uses the more advanced photocatalytic oxidation technology:
Surround Air Multi-Tech Ionizers
Negative ions clean the air by magnetically attracting to pollutants until these newly-formed larger particles become too heavy to remain in the air you breathe and they fall to the ground. Surround Air Ionizers continually produce negative ions, without creating the "black-wall" effect of older ionization technologies, so even if one of these fallen particles is kicked up into the air, it is quickly removed again. The most important thing, though, is that they are taken out of the air, preventing you from inhaling them into your lungs, which is how they cause problems.
Since certain technologies are much better than others at removing different types of air pollutants, all Surround Ionizers are multi-technology. All models include ionization, a prefilter, a HEPA and Carbon Filter and UV lamp, plus some models include a TiO2 filter or an optional ozone sanitizer. And, the Intelli-Pro includes electronic sensors. With Surround, you get the best of the most advanced air purification technologies on the market, all rolled into one air purifier. The best part is that Surround Multi-tech ionizers and replacement filters are affordable for every budget. more info
No air purifier on the market can compete in effectiveness, energy efficiency, adaptability and quiet operation, when compared to the Air Oasis G3 patent-pending Nano Nickel HCT photocatalytic oxidation technology. Other oxidation brands use only titanium dioxide (TiO2) as a catalyst, the cheapest, most available catalyst metal on the market, whereas Air Oasis contains five rare catalyst metals and nano size metals to increase the kinetic rate of reaction.
Unlike HEPA filters that only remove some particulate and carbon filters that only remove chemicals, VOCs and odors, Air Oasis technology is proven effective against MRSA, bacteria, molds, VOCs, chemicals, gases, odors, pollen, dander and more. Extensive testing conducted by West Texas A&M University at BSA Hospital confirm that Air Oasis not only purifies your air, but sanitizes surfaces, too. Additionally, Air Oasis Air Purifers are made in the USA, using brushed aluminum casings and UV lamps that utilize a proprietary long life coating, allowing them to outlast any UV lamp on the market.
