Within the room air purifier market, there is seemingly endless technology available. The large majority of available small room air purifier products fit into one of two categories: mechanical purifiers or ionic air purifiers. While both of these air purification technologies are currently being introduced into restaurants, medical offices, hotel rooms, and school buildings, there are a few key differences that can help you pick the right air purifier for your situation. 

Mechanical air purifiers work by passing air through layers of filters that capture airborne particles. The most common mechanical filter, the HEPA filter, was initially commercialized in the 1950s.  Filters meeting HEPA standards capture 99.97% of particles down to 300 nanometers in size. Ionic air purifiers work differently, generating electrically charged ions that bond with particles to make them easier to capture.  While they can filter out airborne pollution, they can also outgas ozone and other compounds into the air. 

How is the G200 different?

As air purifiers become more popular, other types of filtration technology have entered the market, all with different cleaning methods and levels of filtration. When evaluating these room air purifiers, it’s important to consider what you’re trying to filter out of your air, and which filters are the most effective for those elements. 

Some of the most dangerous particles in the air are also the smallest. Particles that are 2.5 micrometers in diameter or smaller can pose significant health problems, as they can pass through the nose and throat and enter the lungs. These fine particles can irritate allergies and agitate asthma, often causing respiratory distress or damage. Ultrafine, or nanoparticulate, pollution, includes particles smaller than .1 micrometers. These particles are so small that they can pass through the lungs into the bloodstream.

Combining proven technology with innovative mechanical filtration unique to Celios, the G200 uses three filters and super-fast, turbulent air flow to clean the air in your room. The G200 air purifier captures up to 99.99999% of particles in the air down to 10nm, including particles well below the size of most viruses. 

The Three Filter System

The Celios G200 Advanced Air Purifier delivers cleanroom quality air, providing ultrafine purification of the air’s most dangerous compounds. This includes particles smaller than airborne viruses including influenza and rhinovirus. The Celios G200 Advanced Air Purifier is also effective at capturing the SARS-CoV-2 virus.(1) The small room air filter uses three filters to eliminate odors, gasses, and volatile organic compounds (VOCs). 

  • An oversized activated course Carbon Filter effectively eliminates odors, gasses, and volatile organic compounds (VOCs)
  • Pre Filter captures larger particulate matter and creates turbulent airflow 
  • The Core Filter contains specialized filtration material designed for medical and cleanroom applications, unavailable in other consumer products until now

In order to ensure the air coming out of the G200 is of cleanroom quality, the purifier maintains a sealed closed system. Unlike other air purifiers relying on chemical reactions to clean the air, Celios’ advanced mechanical air filtration does not generate foul odors or chemical outgassing. The three-filter design creates filtration that is up to 3,000 times more efficient than HEPA filtration standards and captures particles up to 30 times smaller, providing cleanroom-quality air in small room environments. 


(1) The Celios G200 Advanced Air Purifier meets the performance and labeling requirements provided in the U.S. FDA’s March 2020 Enforcement Policy for Sterilizers, Disinfectant Devices, and Air Purifiers During the Coronavirus Disease 2019 (COVID-19) Public Health Emergency, published March, 2020 (the Celios G200 has not been cleared by the FDA). Specifically, the Celios G200 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 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 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 with any solid-state speed control device. Unplug or disconnect from the power supply before servicing. Appliance is only to be used with the power supply unit provided with voltage corresponding to the marking on the appliance. Do not operate with a damaged cord or plug. Discard fan or return to an authorized service facility for repair. Do not run cord under carpeting, throw rugs, furniture, or appliances. Arrange cord where it will not be tripped over. Do not allow children to operate or play near the G200. Only plug the power cord into a standard electrical outlet. Do not use outdoors. Do not immerse the G200 in liquid and do not handle the G200 with wet hands. Do not insert a finger or foreign object into the airflow openings. Do not use the G200 in toxic or explosive environments or where flammable or combustible gases are present.
