New 6-month bulb warranty resets. Month 12 Standard Warranty Ends Without Guardian Club: no unit or bulb coverage. With Guardian Club: lifetime unit coverage continues. Cost BreakdownReal-world shipping and cost responsibilities across common warranty situations.
| Situation | Who Pays | Customer Cost |
|---|---|---|
| Unit warranty claim — first 6 months | BioShieldUV pays for the unit and the bulb | $0 |
| Unit warranty claim — 6 to 12 months | BioShieldUV pays for the unit; after the included bulb's 6-month warranty, the replacement bulb is invoiced to you. The unit and the bulb always ship together — we never send a bulb on its own, because a failed bulb and a failed ballast cannot be told apart without both parts in hand. | Bulb only |
