Buying Guide
What to consider when choosing a UV lamp for AC
System compatibility matters. Check whether your HVAC unit is ducted or uses coil configurations, and verify ballast compatibility with the lamp’s base.
Wattage and lamp strength affect disinfection. Higher wattage generally provides stronger UV-C output, but ensure safe operation and correct installation to prevent ozone production and UV exposure.
Ozone emission is a key safety factor. Look for EPA, CARB, or third-party certifications and ozone limits (ideally zero or well below 0.05 ppm).
Mounting and installation ease. Magnetic or external power options can simplify installation for renters or non-permanent setups, while in-duct models require more permanent mounting and wiring.
Maintenance and replacements. Consider bulb lifespan, replacement frequency, and availability of compatible bulbs from the same brand or line to avoid compatibility issues.
Installation footprint. Review the physical dimensions and mounting space required in ducts or on coils to ensure a proper fit without obstructing airflow.
