UV Air Purifiers, like the Germ Killer UVC 200, help reduce disease transmission such as the flu in medical facilities and heavily populated areas.
With the sharp rise in flu activity this winter, facilities can implement UV Air Purifiers to help reduce disease transmission and keep staff, customers, and patients healthy this season. According to the CDC, there have been an estimated 11 million illnesses, 120,000 hospitalizations, and 5,000 deaths from influenza (data ending week of December 31st) (Cobern 2026). This represents a significant increase from the estimated figures before the holiday, with hospitalizations up 48% (Cobern 2026). Most of the flu cases this season have been caused by a new flu strain called subclade K, a variant of the H3N2 virus and a subtype of influenza A. CDC has shown a steady increase in respiratory illness activity levels by state just from last week. Last week, 20 states were at a very high level, and this week it’s up to 32 states (Cobern 2025 & CDC Dec 2025). Also, last week only 9 states were at a high level, now 16 states are this week (Cobern 2025 & CDC Dec 2025).

December 2025 CDC Wastewater Data for the Flu
According to the CDC wastewater data, influenza levels are rapidly climbing. Data from after the holidays shows a further increase. The national average has doubled each week since December 13th:
Week ending 12/27: 12.29/high
Week ending 12/20: 6.43/moderate
Week ending 12/13: 3.26/very low
Please look at the chart below to see the increasing flu activity from wastewater data by section of the US (CDC 2026).
| Area of the US | 12/27 | 12/20 | 12/13 |
| National Average | 12.29 – high | 6.43 – moderate | 3.26 – very low |
| Midwest | 13.61 – high | 6.00 – moderate | 2.2 – very low |
| South | 10.97 – moderate | 6.67 – moderate | 3.66 – very low |
| Northeast | 14.10 – high | 11.54 – high | 6.53 – moderate |
| West | 8.21 – moderate | 6.2 – moderate | 2.87 – very low |
Flu & Disease Prevention Strategies
To help prevent flu and other disease transmission, the CDC recommends implementing the following best practices (CDC April 2025):
• Get the influenza vaccine
• Use proper hand washing techniques and cough etiquette
• Disinfect frequently touched surfaces
• Isolate infected individuals
• Implement engineering infection controls such as UV Air Purifiers
Using UV Light Air Purifiers as an Engineering Control to Help Reduce Flu Levels
The Germ Killer UVC 200 helps reduce disease transmission and keep staff, students, and/or patients healthy.
How effective is the Germ Killer UVC 200 with influenza and other pathogens?
To illustrate the effectiveness of the Germ Killer UVC 200 – our experts calculated the average fluence of the UV light lamps coupled with log reduction calculations. Our team found the Germ Killer to be up to 99.999% effective on Influenza A. Please see the chart below for more calculations for effectiveness of different pathogens.
UVC Dosage Effectiveness by Pathogen (1 log reduction = 90% reduction, 2 log = 99%, etc)

| Pathogen | Approx Dose per Log Reduction (mJ/cm2) | # of Log Reduction | Estimated % Reduction* | # of Log Reduction | Estimated % Reduction* |
| Influenza A$ | 0.85 | 6.8 | >99.9999% | 4.47 | 99.9966% |
| SARS-CoV-2 | 2.5 | 2.3 | 99.5214% | 1.52 | 96.9800% |

| Salmonella Enteritidis | 4 | 1.5 | 96.4519% | 0.95 | 88.7798% |
| Salmonella typhi ATCC 19430 | 1.8 | 3.2 | 99.9401% | 2.11 | 99.2257% |
| E. Coli O157:H7^ | 3.5 | 1.7 | 97.7978% | 1.09 | 91.7911% |
* The data listed assumes a linear relationship between UV-C and log reduction of microorganisms based on testing conducted in UV-C irradiance. Actual results may vary.
^ There are many different types of E. Coli. O157:H7 represents the most dangerous type to humans.
$ Levels of humidity can affect the dose required. The higher the humidity, the higher the dose. Dose shown is 50% RH.
The Germ Killer UVC 200 can help with flu prevention in workspaces and conference rooms.
