The Nobel Prize in Medicine was won in 1903 by Niels Finsen for treating tuberculosis with ultraviolet light. Ultraviolet lights have since been adapted for a wide range of uses including sterilizing water, germicidal lamps in food establishments, sterilizing hospitals, as well as curing nail polish faster. Now, UV lights are even used to improve the quality of the indoor air inside homes and businesses. As proven, UV lights in the HVAC system can destroy mold and other microbe growth among offering other benefits. Today we at Air Pure Air Duct Cleaning would like to elaborate on the use of UV lights in your HVAC system.
Types of UV Lights for HVAC Systems
There are two types of UV lights designed for HAVC systems; coil sterilization and air sterilization.
Coil Sterilization: Sterilizing the air handler coil is a stick-type light, that is installed inside the return air duct. The most common type of HVAC UV light, the UV light runs 24/7 as it is a coil sterilization; and typically, the more affordable option as well.
Air Sterilization: Sterilizing moving air, the air sterilization is a complete UV light unit that is installed in the return air duct and is designed to cycle with the air handler blower. There are quite a few top-rated products to provide maximum efficiency.
Study of UV Lights in HVAC System
Proven Effectiveness with Science: To separate studies validate the effectiveness of UV lights eliminating mold and bacteria; both in commercial HVAC system and the second, in hospital applications.
Study of commercial HVAC system: After 4 months of functioning in a commercial office building, the fungal levels in control AHUs, air handler units, were significantly lower following UV operation when testing the effectiveness for reducing fungal contamination within air-handling unit with the germicidal UV radiation.
Study in hospitals: To nearly eliminate drug-resistant bacteria in 50 hospital room, in 2012, researchers at Duke University Medical Center used ultraviolet radiation (UV-C) by reducing the number of bacteria by more than 97% with the ultraviolet light effective in hospital infection control.
How to Improve Indoor Air Quality in Home or Office
When taking advantage of the UV lighting effects for killing mold, bacteria, germs and odors, there is additional basics you need to apply to improve the effectiveness.
1) During any renovation or construction, seal off the air ducts.
2) In HVAC system, install UV light.
3) Should your HVAC system be designed for the higher static pressure of better filtration, install high-MERV filters.
4) In conditioned space, install ducts.
5) Ensure air-tight ducts, sealing all joints with mastic.
6) Changing filters monthly and cleaning the coil annually and conduct other regular maintenance.
Benefits of HVAC UV Lights
– VOCs removal.
– Germs are not re-circulated by HVAC system to reduce colds and flus.
– Mold and bacteria control
– humid climates have an increase in effectiveness than dry climates do.
– By preventing algae growth clogging in condensate drain lines is reduced.
– Smell and odor manifestation are reduced.
