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

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!

I've had my three GermGuardian GG1000's going on for about 4 years now and never replaced the bulbs. The UV bulbs seem to have been working throughout the entire time; none burned out. So I never really thought about it even though I did see recommendations for them to replacement every six to eight months. It's been hard to say if they're effective in the first place; I sort of have them as a peace of mind. Recently I read a comment from another reviewer about how they loose effectiveness even if they still seem to be working. So just decided, heck, why not. So I replaced them just now. After cleaning them and opening them up, I noticed one of the bulbs had burn marks. It was extremely easy to open up, twist out the bulb and put in the new one. The new bulbs are a tad bit shorter than the original but fit in just as well. I immediately noticed how much brighter the UV light was. Maybe I'll notice a bigger change in the air quality now.TL;DR: Shorter than normal, and worth replacing even if not following the recommended timeline but very easy to change out.

It seems to work okay, but... when you get right down to it, there's really no way to know, right? It lights up, though, and it fit perfectly in my GermGuardian GG1000. My only complaint is it needs to be replaced every six months, which seems a little ridiculous.

Works fine, but these things wear out much more quickly than I'd like. Decided to just not run mine anymore since the fan bearing also went out and it uses enough electricity that I feel it wasn't worth it anymore. But this bulb itself is fine and gets the sanitizer running again.

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!

I used to be a hearing aid dispenser for Costco and had a Dr. for a patient who was interested in holistic health. We had many discussion about holistic health and he recommended I get the Germ Guardians for my house since I was around potentially sick people often working at Costco.My husband had also had a Liver Transplant due to a Bile Duct disease and so is immune system compromised. Once we bought these we literally have never gotten sick except my husband who got sick after being around very sick people(we have to keep that to a minimum but sometimes we just don't know). We have now had our Germ Guardian's for 7-8 yrs. and would not be without them. We have one in our kitchen and one in our masterbath would like to have others but they cover germs for a large area so haven't purchased anymore. We have only replaced the bulbs one time previously...My Dr. patient had been using them for several yrs. and he never got sick..... Obviously if you are stuck around really sick people you might...

Bulb was defective. Didn't light up once installed. I ordered a germ guardian bulb at the same time that I ordered an off-brand replacement UV bulb for my Germ Guardian plug-in air purifier. The Germ Guardian bulb didn't work. But the off brand bulb replacers worked beautifully. So I guess I'm going to go with the off brand. Amazon return menu let me select the option for defective product didn't work. But it wouldn't let me hit the continue button to return the product I don't know why that is. So if Germ Guardian is reading this can you send me a bulbs that works? Cuz your bulbs are more than twice the price of the off-brand bulbs.

I use these in my air purifier next to the dogs. You can easily tell the different when the UV-C bulb is on vs off. This takes care of the dog funk that lingers even with good filtration.
