Other Air Cleaning Technologies
What we have listed above is the best way to remove airborne dust particles from the air. There are some other technologies used in air purification units.
The purpose of this section is to highlight them. Though as it relates to helping with your dust mite allergy or less dust to improve indoor air quality, these offer little to no benefit.
UV-C light can be effective in preventing growth of all types of household mold. Especially if you have a strong ultraviolet light in your forced-air heating system. But if what you are looking for is to kill dust mites or breathe better with less dust in the air, then a UV-C germicidal lamp will not do it.
This is because UV lamps are not able to capture airborne dust particles. It simply shines a powerful light that keeps things like mold and mildew from growing. If you suffer from allergies and asthma from mold then an air purifier with UV light may be a good option.
Plasma technology is a more recent innovation in the world of air purification. The two most popular are plasmawave technology and plasmacluster technology.
My understanding is these are marketing terms for the use of positive and negative ions. This is somewhat similar to an ionic air purifier where electrical charges are used to make it easier to catch the HEPA filter.
Since this is a newer technology, there is some concern around ozone being produced as a by-product. In a sense a secondary pollution. You have the potential for ozone generation any time you emit electrical charges.
As it relates to the removal of dust, this technology can provide some benefits. Our approach is different. We feel if you use super high quality filters, you don't need to use electrostatic technology to remove airborne allergens. As allergy and asthma sufferers ourselves, it's not worth it to create an indoor air pollutant.
