What are UV-C Disinfection Lamps?
UV-C disinfection lamps emit radiation in the UV-C portion of the ultraviolet (UV) spectrum, which includes wavelengths between 100 and 280 nanometers (nm). The lamps are used in a variety of applications where disinfection is the primary concern, including air and water purification, food and beverage protection, and sterilization of sensitive tools such as medical instruments. Germicidal light destroys the ability of bacteria, viruses, and other pathogens to multiply by deactivating their reproductive capabilities. The average bacteria may be killed in 10 seconds at a distance of 6 inches from the lamp. The wavelength with the greatest effectiveness is 253.7 nm, which defines the germicidal lamp category with optimized wavelength for maximum absorption by nucleic acids.

Hazard and Risks from UV-C Disinfection Lamp Radiation
UV-C radiation (UVR) used in most disinfection bulbs is harmful to both skin and eyes.
UVR is not felt immediately; in fact, the user may not realize the danger until after the exposure has caused damage. Symptoms typically occur 4 to 24 hours after exposure.

The effects on the skin are of two types: acute and chronic. Acute effects appear within a few hours of exposure, while chronic effects are long-lasting and cumulative and may not appear for years. An acute effect of UVR is redness of the skin called erythema (similar to sunburn). Chronic effects include accelerated skin aging and skin cancer.

UVR is absorbed in the outer layers of the eye – the cornea and conjunctiva. Acute overexposure leads to painful temporary inflammation, mainly of the cornea, known as photokeratitis. Subsequent overexposure to the UV is unlikely because of the pain involved. Chronic exposure leads to an increased risk of certain types of ocular cataracts.

Working unprotected for even a few minutes can cause injury. It is possible to calculate the threshold for acute effects and to set exposure limits. It is not possible, however, to calculate the threshold for chronic effects; therefore, because no exposure level is safe, exposure should be reduced as much as possible.

10 CFR 851 mandates the use of the threshold limit value (TLV) exposure limits established by the American Conference of Governmental Industrial Hygienists (ACGIH). The exposure limit for a germicidal lamp is 6 millijoules per square centimeter. At this level, detectable molecular damage appears to be fully repaired within 24 hours. For the case of continuous exposure for longer than 8 hours, special care needs to be taken.

Air Mode: Tips to Replace the HEPA Filter
The current pandemic has raised awareness and questions centered around best practices to follow for
air filter replacement. Here are some recommended steps to replace an air filter:

1. TURN OFF THE POWER for safety. Also, turn off any fans in the area at least 20 minutes prior to servicing a filter.
2. Wear personal protective equipment (PPE): This includes a face mask, nitrile gloves, and shoe covers.
3. Remove the old filter. Simply slide it out of the slot that holds it in place.
4. Check the condition of the filter. Does it look clogged with dirt and dust? Many factors can impact how fast a filter will become clogged, shortening the life of the filter.
5. Replace the filter. Immediately place the old filter into a plastic bag being careful not to shake or drop it. Sudden movements can cause microscopic particles to be released into the air. Twist or tie the bag shut and consider taping it to create a seal.
NOTE: If the filter has a permanent frame, the media should be removed outside. Be sure to dispose of the old filter in an outdoor trash can.
6. Insert the new filter right away. An arrow on the filter’s frame shows the direction that air should flow through the filter, which is always away from the return air duct and toward the air handler mechanism. When inserting the filter back in the housing, make sure that the arrow points away from the return and toward the air handler. Write down the date you replaced the filter.

To maintain healthy breathable indoor air, standard HVAC air filters should be changed at least every three months. In some situations, the filter may need to be changed more frequently. Changing an air filter on a regular maintenance schedule also keeps equipment in top working condition, prevents breakdowns, reduces energy consumption, and limits expensive repairs.

Extra safety cushion provided by the internal UVC lamps
The HEPA filters in this AIR Unit are irradiated continuously by the UVC lamps above the HEPA filters. So, in general, most of the dangerous pathogens trapped on the HEPA  filters have been inactivated before the technicians replace the HEPA filters. However, the UVC light can not penetrate the dust and particles, so if some pathogens are hidden underneath the dust and particles and were not irradiated by the UVC light, they might still be dangerous to technicians.
