What is the Difference Between the G200 Filter and a Standard HEPA Filter?

When discussing air purifiers, one of the most common filtration methods is the use of a mechanical HEPA filter. Mechanical filtration is often preferred to active filtration methods such as photocatalytic filters and ionizers, this is because such active methods of filtration potentially pose a health risk because they can create harmful byproducts. While HEPA is often the first affordable mechanical method that comes to mind for portable air filters, there are now other options on the market that offer better filtration. 

Behind HEPA’s Popularity

A HEPA filter is any air filter that meets the HEPA standard as defined by the U.S. Department of Energy. It was first developed in the 1940s to keep potentially radioactive particles contained and has since evolved. By the 1960s, this technology had moved into the consumer market as filters for HVAC units, vacuum cleaners, and stand-alone air purifiers. Since then, little has been done to modernize or improve upon mechanical filtration devices. 

Similar to other mechanical filters, the sheets of fibers are folded into pleats to increase the surface area. Air flows through the filter, and particles get trapped when they hit these pleats. HEPA filters tend to work well for larger particles such as pet dander, pollen, and dust mites but are not as effective at capturing smaller harmful pollutants or airborne chemicals under 300 nanometers. Many viruses, volatile organic compounds, and bacteria also fall under this size threshold. 

Introducing New Options

As you can imagine, technology has evolved exponentially since the 1960s, yet the HEPA filter has remained one of the most popular filtration methods despite the fact that its standards for filtration have remained the same. It was once thought that this was the best you could do when it came to mechanical filtration methods, but new technology has allowed us to see this is not the case. 

In recent years, we have seen new chemical and ionic filtration methods become available, but we have also seen enhancements in mechanical filtration technology that allows for more efficiency at removing particles from the air. 

G200 vs. HEPA

The G200 Advanced Air Purifier was designed to create a more precise air purification system that relies solely on mechanical filtration methods. 

HEPA filtration standards say that the filter must capture 99.97% of any airborne particles with a size of 300 nanometers. In contrast, Celios’ patented technology provides up to 99.99999% filtration efficiency. It can capture ultrafine particles down to 10 nanometers (or .01 micron) in size. This makes it up to 3,000 times more efficient than HEPA standards and captures particles up to 30 times smaller.

Ultrafine particles, less than 100 nanometers (or 0.1 microns) in diameter, are the most harmful and typically the most abundant type of air pollution. Unfortunately, these ultrafine air particles are too small to be effectively captured by HEPA standard air purifiers and other filters on the market today. Leveraging its three filter system, the G200 captures ultrafine particles, allergens, pollen, mold spores, VOCs, bacteria, and viruses. It is effective at capturing the SARS-CoV-2 virus. (1)

Specifically, the Celios G200 Advanced Air Purifier has demonstrated up to 99.99999% filtration efficiency of ultrafine airborne particulate matter and is capable of filtering particles down to 10 nanometers in size. The Celios G200 Advanced Air Purifier has also demonstrated up to 99.99999% virus filtration efficiency of ΦX174, a small bacteriophage virus with a maximum diameter of ~32 nanometers.

The G200 Advanced Air Purifier is not intended to prevent or protect from any form of illness or disease (or otherwise). To reduce the risk of fire or electric shock, do not use this fan with any solid-state speed control device. Unplug or disconnect the appliance from the power supply before servicing. The appliance is only to be used with the power supply unit provided and it must only be supplied with voltage corresponding to the marking on the appliance. Do not operate any fan with a damaged cord or plug. Discard fan or return to an authorized service facility for examination and/or repair. Do not run cord under carpeting. Do not cover cord with throw rugs, runners or similar covers. Do not route cord under furniture or appliances. Arrange cord away from traffic areas and where it will not be tripped over. Do not allow children to operate the G200 Advanced Air Purifier or play near the G200 Advanced Air Purifier. Only plug the power cord into a standard electrical outlet. Do not use outdoors. Do not immerse the G200 Advanced Air Purifier in liquid and do not handle the G200 Advanced Air Purifier with wet hands. Do not insert a finger or foreign object into the airflow openings. Do not use the G200 Advanced Air Purifier in toxic or explosive environments or where flammable or combustible gases are present.
