Replacement UV-C bulbs for air purifiers

This two-pack supplies 5-watt UV-C lamps with a G23 two-pin base. Each bulb measures 1.25 by 1.25 by 4.12 inches and emits ultraviolet light at a 4000 kelvin colour temperature. They are built to fit the LB4000 slot used in several GermGuardian purifier models. Homeowners maintaining compatible units can install them without tools.

Suits owners of listed GermGuardian models

The bulbs match purifiers including the AC4825, AC4850, AC4850PT, AC4300BPT, AC4300BPTCA, AC4900, AC4900CA, AC4800, CDAP4500, AC5300B, AC5350B and AC5350W. Buyers with a different brand or a model not shown in the compatibility list should look elsewhere. The G23 base and 5-watt rating are fixed, so any unit requiring a different pin layout or wattage will not accept these lamps.

Two bulbs per pack extend service intervals

Having a spare on hand means the purifier can return to UV-C operation immediately after the first bulb reaches end of life. No additional hardware, adapters or software are included in the package. The only change for the user is a faster swap when the indicator signals replacement.

Questions about this item

Which GermGuardian purifier models accept the G23-base 5 W UV-C bulb in this 2-pack?

The bulbs fit AC4825, AC4850PT, AC4300BPTCA, AC4300BPT, AC4850, AC4900, AC4900CA, AC4800, AC4900, CDAP4500, AC5300B, AC5350B and AC5350W units.

Will the 4.12-inch tubular lamps operate in a purifier that originally shipped with a shorter UV-C bulb?

Each lamp measures 1.25 in × 1.25 in × 4.12 in; verify the purifier’s lamp chamber accommodates that length before installing.

How can I confirm the UV-C output is active after replacing the bulbs?

The lamps emit ultraviolet light at 4000 kelvin; many GermGuardian models show a blue indicator glow through the viewport when the UV-C cycle is running.
