Replacement Bulb for Germ Guardian Air Purifiers

This two-pack supplies G23-base UV-C bulbs rated at 5 watts for use in compatible Germ Guardian air purifiers. Each tubular lamp delivers a white tone with a CRI of 80 and an average life of 10 months. Installation is tool-free behind the filter and the bulbs work immediately after fitting. They are not manufactured by or affiliated with Germ Guardian.

Thermals Noise and Power Draw in Normal Use

The 5-watt rating keeps power consumption low during continuous operation. UV-C light combines with titanium dioxide to reduce volatile organic compounds without producing ozone. The lamps also help isolate pollen and dust mites while the purifier runs at normal speed. No audible noise or excess heat is generated by the bulbs themselves.

Sustained Load Behaviour Over Months

Replace the bulbs every 10 to 12 months depending on environmental factors and intensity of use to maintain effective UV-C output. The two-pack provides a spare so the purifier can stay in service without interruption. Output declines gradually rather than failing suddenly, so scheduled replacement preserves air-treatment performance.

Questions about this item

How is the Poweka LB4000 UV-C bulb installed, and which step is often missed?

Open the rear cover behind the filter, pull the old G23 2-pin bulb straight out, and push the new one in until both pins seat fully; the step people miss is checking that the retaining clip clicks back into place.

What maintenance or replacement will the Poweka LB4000 bulb need later?

Replace the UV-C bulb every 10 to 12 months depending on environmental factors and usage intensity; the pack includes two bulbs for the next change.

What limit appears first under sustained use of the Poweka LB4000 bulb?

The 10-month average rated life is the first limit; after that UV-C output drops and germ-reduction effectiveness declines.
