An educational comparison of warranty coverage across HVAC UV-C brands — so you can make an informed decision about protecting your air purification system.
Educational Purpose Only Hire a Licensed Professional for Installation No Pesticidal Claims Made Standard CoverageEvery BioShieldUV system includes a 1-year limited warranty covering the unit components — ballast, housing, electrical connections, and mounting hardware — against manufacturing defects and component failures under normal use. bioshielduv.com
After that 1-year limited warranty ends, a shopper who is not a Guardian Club member has a 30-day grace on the unit, counted from the purchase date when no delivery scan is on file. During that grace a replacement unit is half the price of the unit and the replacement bulb is included. After the grace, a replacement is a full unit at retail. A bulb bought on its own is not refunded, including when the unit is the part that failed. bioshielduv.com
Manufacturing defects in materials and workmanship, component failures under normal operating conditions, ballast malfunctions, housing and mounting hardware defects, and electrical connection failures. bioshielduv.com
TruBlue™ UV bulbs (separate policy applies), damage from improper installation, power surges, normal wear and tear, misuse, environmental damage, or units modified by unauthorized persons. bioshielduv.com
The bulb that comes with your unit is covered for 6 months. If the bulb included with your BioShieldUV unit fails within 6 months of delivery, we replace it at no cost.

A bulb bought on its own is not refunded, including when the unit is the part that failed. Guardian Club members get a 6-month warranty on every bulb. bioshielduv.com
