    • Bulb longer than original in unit
This bulb is longer than the original one in the unit. Even if you remove the safety cover it’s still too long doesn’t fit how it should in air purifier. Hey GermGuardian sell us the same length bulb?

    • Tight Fit
I had to shift the bulb around quite a bit to make it actually fit in the slot because of a part of the glass tip that extended about half a mm further than the end of the bulb that was originally in there. I was worried about it breaking, but I eventually got it to work.

    • Bulb looked different
It didn't have a small safety cover (on the tip of the bulb) that's necessary when you place it in the unit. I had to use the one from the old bulb. Not sure if it was the right thing to do. Also it would be helpful if it had an instruction how to change the bulb. Update to my review: I changed one start to five after I called their help number, and I found out that the bulb doesn't come with that plastic safety cover and it doesn't need one. Per their rep, the original probably comes with it to secure the bulb during shipping and handling. ... show more

    • Easy switch and fix. Germ killing machine!
This product was and is Awesome. I love my germ guardian air filter. Well so much so, that the bulb went out 😃. Anyways, this was a super easy purchase, with just as easy of switching out the bulbs. Only need a Phillips screw driver and you can switch your bulb to make sure that your still killing those germs! ... show more
