Buying Guide: Key Considerations For In-Duct UV Air Cleaners

  • UV wavelength and output: Most effective units use 253.7 nm UVC. Higher wattage provides stronger disinfection but may require proper safety precautions and power handling.
  • Installation style: In-duct, magnetic mount, or external ballast setups each suit different HVAC layouts. Assess access to ducts and existing wiring before choosing.
  • System compatibility: Check coil size, duct dimensions, and HVAC tonnage to ensure the UV lamp or kit covers the intended air volume.
  • Ozone considerations: Many units advertise ozone-free or low-ozone by-products. Verify regulatory compliance and local guidelines if ozone exposure is a concern.
  • Power requirements: Some kits run on standard 120V or 24V systems. Consider whether a dedicated transformer or external socket is necessary.
  • Maintenance and replacement: UV bulbs degrade over time. Note replacement frequency, bulb availability, and ease of access for maintenance.
  • Safety and installation: Follow product guidelines for electrical safety, avoid direct skin exposure to UV light, and consider professional installation for duct work.
