"Why Just treat the symptoms, when we need to eliminate the sources."

Existing solutions of air filtration are inadequate, SEECC LLC shows the comparisons in a simple format.

Air Purification Technologies Comparison

This section contains quick explanations and criteria to help you decide what filtration method is best for a given problem. You should be familiar with the pros and cons for all the filtration and purification methods listed below.

Filters are the most common filtration method. In general, filters must permit some pollutants to pass with the airflow. The higher the efficiency or density of the filter, the lower the airflow and higher the restriction to the blower.

HEPA stands for high efficiency particulate air filter. HEPA filters utilize a powerful blower to force the air through a very tight membrane to achieve high efficiency particulate filtration.
Pros:
They are very efficient in the filtering of air that passes through the filter. They filter to .03 micron.
Cons:
They require filter changes. The filter can act as a breeding ground for bacteria, mold and fungus. They do not remove odors, gases, pesticides, viruses, and many bacteria. They reduce airflow due to the tight pores of the filter. They are generally not used in central systems, and sold as stand-alone units only.
