HEPA, High air flow restriction: True or Absolute HEPA is a very dense paper media with filter efficiency of 99.97% at .3 micron. This is great for efficiency but can result in poor air cleaner performance more specifically reduced airflow. You can have the most efficient filter in the world but if you do not move enough air your air cleaner is ineffective. Many manufacturers make the claim of silent HEPA. The physics behind mechanical filtration are, if you have a dense media you need a strong motor and blower to really push the air through the filter this results in NOISE. In most cases manufacturers are not pushing any air through their machines on low or medium speed and they are claiming silent or quiet. This may be the case but they are not providing effective air cleaning either. On high speed HEPA systems are providing clean air at 99.97% efficiency at .3 microns, but they sound like a jet taking off.
 , Lower air flow restriction: The main filter is less dense around 85% at .3 micron, but within the system the high energy field raises the efficiency of the filter to 99.99% at .3 micron without restricting the airflow like a HEPA. The end result is better overall system efficiency than HEPA with much more airflow. This can also be done much quieter because the motor and blower do not have to work as hard to push the air through the filter.
HEPA, LOADS QUICKLY: HEPA’s dense media filter can load with particulates rather quickly. Most HEPA systems are on timers therefore not truly indicating when filters actually need to be changed. In many cases these filters need to be changed every six months.
, LOADS SLOWLY: - with a less dense media filter you can expect 4X the loading capacity of a similar sized HEPA. With true filter monitoring by pressure drop we can indicate when the filter has reached its maximum loading capacity. The main filter incorporates Spun Sealed Technology which ensures every filter is 100% sealed. This will guarantee the consumer is receiving maximum performance from their machine.
HEPA, microorganism breeding ground: it has been long known that after HEPA media filters become coated they may have the tendency to create a breeding ground for bacteria. When moisture is built up in a filter, bacteria, viruses, and fungi have a better chance of staying alive and incubating or reproducing. This can create a very dangerous environment inside the filter media. If filters are not changed timely microorganisms may possibly breed through the filter or disperse back into the environment when changing the filter.
, holds and kills microorganism: filtration was developed by focusing on this exact issue. Two metal grids, one on the top of the filter media, and one below the filter media contains 18kv of energy. This creates an uninhabitable environment for microorganisms to reproduce in the filter.
