Polarization is very different from ionization,” explains Duke Wiser, president of Dynamic Air Quality Solutions, the leader in manufacturing products using polarized-media technology. “A polarized field does not produce any ozone, which occurs with ionizing. And polarized molecules are not charged and therefore less apt to collect where you don’t want them to. By contrast, ionized particles have either a positive or negative charge and are attracted to oppositely charged surfaces such as collector plates in precipitating air cleaners. But charged particles can also collect on walls, ductwork, and clothes.
Polarized particles are bi-polar which means that each molecule charge (at one end) and a negative charge (at the other end). Polarized particles are attracted to the other polarized particles that tend to float free and are recirculated through an HVAC system.
Polarizing produces no Ozone.
Polarized media air cleaners increase in efficiency as the media loads.
Ionized particles are either positively charged or negatively charged. An ionized particle is attracted to an oppositely charged surface such as a collector plate and precipitating air cleaner.
Ionizing can produce Ozone as a by-product.
Precipitating air cleaners lose efficiency as Ionizing wires and collecting plate surfaces get dirty.

Any air cleaning system’s effectiveness will be, in part, determined by the air change rates, airflow patterns, and contaminant generation rates,” continues Wiser. “Typically in a house we see particle reductions of 70-90%, but because of the low air change rates in a home, it may take a few days. In a casino, on the other hand, even though the contaminant level and generation rates are much higher, the air change rates are over ten times higher than in a house, so significant reductions in both particles and VOCs are almost immediate.
