Our most popular and effective unit is the Bio-Net Air Purifier.
Below we give you a comparision between a typical HEPA and Bio-Net's patented EGF (Enhanced Germicidal Filtration) Filter:

What is HEPA Exactly?

HEPA is a type of air filter. It is an acronym for “High Efficiency Particulate Air (filter)” as officially defined by the United States Department of Energy.

This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns at 85 liters per minute. The diameter specification of 0.3 microns responds to the worst case, the most penetrating particle size (MMPS). Particles that are larger or smaller are trapped with even higher efficiency. Using the worst case particle size results in the worst case efficiency rating (i.e. 99.97% or better for all particle sizes)

There is nothing in the definition of HEPA Filter, which prevents an air purifier designer to combine traditional passive filtration technology with active electrostatic field enhancement to achieve higher retention efficiency. The Bio-Net achieves greater than 99.97% particle reduction and is verified by a particle counter.

Each manufacturer has his own philosophy how his product will achieve the goal which in the case of air purifiers is to provide a cleaner environment than would exist without the air purifier in operation. Other manufacturers opt to combine two or more filtration technologies with the same clean air results. Because the methods are different does not mean that one air purifier is “better”, “more efficient” or “superior” to all other air purifiers.

First you have your True HEPA systems ex - IQ, Austin, and Blue Air. All these machines are indicating that their total system efficiency is 99.97% at 0.3 microns or better. Total system efficiency means the air coming in the machine will be 99.97% cleaner at 0.3 micron after it has passed through the filter apparatus, in this case the HEPA filter.

Let’s take a look at TRUE HEPA SYSTEMS.
1. High air flow restriction. HEPA filters consist of very dense paper media that reduces 0.3 micron particles 99.97%. 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 many cases manufacturers are not pushing enough air through their machines on low or medium and they are claiming silent or quiet. This may be the case but they are not providing proper air cleaning either. On high we can agree that TRUE HEPA systems are providing clean air at 99.97% at 0.3 microns the problem is they sound like they are taking off like a jet.

2. The Bio-Net Air Purifier uses an EGF main filter which is less dense, around 95% at 0.3 micron, but within the system the High Energy field raises the efficiency of the filter to 99.99% at 0.3 micron without restricting the airflow like a TRUE HEPA. The end result is better overall system efficiency than TRUE 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.

3. HEPA- with a dense media filter dirt loading of the filter can occur rather quickly. Most HEPA systems are on timers therefore not truly indicating when filters actually need to be changed. In most cases these filters need to be changed every six months.

4. EGF- 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. This will always ensure the consumer is receiving maximum performance from their machine.

5. HEPA- it has been long known that after 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 mold 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.

6. EGF- Enhanced Germicidal 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 create 18kv of electricity. We are permeating 100% of the media filter with 18kv of electricity therefore making the filter media uninhabitable for microorganisms to reproduce. Certified Test Data supports 99-100% virus destruction, 98-100% bacteria destruction, 94-100% mold and fungi capture. This process ensures that microorganisms can not breed through the filter and do not have the ability to disperse back into the environment when changing filters.
