GermGuardian LB1000 Genuine UV-C Replacement Bulb for GG1000, GG1000CA, GG1100, GG1100W, GG1100B Germ Guardian Air Sanitizers

Perfect fit replacement bulb for my germ guardian plug in. Changing the bulb in the unit was pretty easy even though I'd heard otherwise. Remove one screw and the top opens giving access to the bulb inside. Simply twist out the old and twist in the new!

Worked great

As described

A bit expensive for small UV lamp, but no other alternatives.

Easy to replace, fit perfectly!

Perfect replacement bulb! (Remember not to touch it with fingers or look at it when on). At first I thought that I'd use these to tinker around so I bought 3 of the bulbs. I make my own HEPA + activated charcoal filters, save a substantial amount of money by doing so, and thought that I might save on the benefits of UV-C, too. I have purchased other brands of air filters that have UV-C light, they were just designed very poorly. For example, a H0neywell, expensive air filtration machine with UV-C was designed such that the UV did not even hit most of the air; the air all bypasses the area that is lit up. It wasn't cheap, either. (I KNOW!!! That's when I started making my own)! Here is the thing, though. Unless you are already the owner of a power adapter that will provide you with the appropriate input for these bulbs, you aren't ahead any money if you have to go and buy one. Trust me, I checked. Add to that the need to make a safe housing so that nobody is looking at the UV-C and possibly damaging their eyesight, and this is one instance in which do-it-yourself does NOT save $$. So, first I bought the replacement bulbs, now I am going back and just buying the Germ Guardian rather than constructing my own housing, and I am quite happy with that (at this time those are selling for about $35). Perhaps it bears mentioning that these replacement bulbs are also economical, while replacing the ill-designed versions that I have here are not effective or cheap. Those replacements alone cost more than an entire Germ Guardian does- I am not at all pleased and because of that it didn't occur to me when I began this quest that there could be other brands that have better business practices. When the health benefits of UV-C are considered, too, this is one great company. If only they all would provide the win-win of good products at fair prices; it is a true public service. OK, hopefully this helps you with your shopping, especially if you like to tinker, too. There are better things for us to mess with! ;) Let me know if this helped, and enjoy your shopping!

This did not resolve the issue. I want to return but the Amazon website won't allow me to even when the item is still eligible for return. The Amazon website just keeps asking for me to check all possible resolutions. None worked for me. I still can't return it. I now have to go directly to the manufacturer to return.
