Works fine. Very reasonable cost and shipping was fast.

Worked ad should

As advertised. Ease to swap the bulbs out.

This product was So Easy to install and worth the price

Nice, I needed a replacement for my Germ Guardian air purifier, but didn't want to pay for the official replacement ones, these not only work just as well, but are much more affordable and you get way more for the price, I'll likely continue buying these ones.

Love it so far

I purchased the six-pack for my Germ Guardian GG1100W, hoping to save on the unit price, considering that the manufacturer appeared to supply commodity 10V, 3W lamps. The original lamp had burned out but still illuminated slightly, so I knew the GG1100W worked, and after about a year in service, it was past time to replace the lamp.Upon receiving the six Qualirey lamps, I attempted to install one in the GG1100W and powered on the GG1100W and nothing happened. This initiated about an hour of troubleshooting the GG1100W and the lamps. Despite testing for continuity, none of the lamps illuminated, even when using a battery, to control for the possibility that the GG1100W was malfunctioning. Oddly, the burned-out lamp glowed slightly when powered. Having read reviews indicating a high failure rate, I initiated a return and ordered a Germ Guardian replacement lamp at a much higher price.When the Germ Guardian lamp arrived, I immediately installed it and went to reassemble the GG1100W. In the process, I discovered a kill switch preventing the device from operating without its top. Since I have been testing the lamps without fully reassembling the device, I decided to retest the Qualirey lamps. This time, four of the six produced violet light as expected while illuminated orange like the original lamp did as it was dying.A one-third failure rate is unacceptable, so I am still going to return the Qualirey lamps and avoid this brand in the future. I am giving a two-star review because much of the hassle this product caused is a result of the design of the GG1000W, which seems intended to frustrate the replacement of the lamp so one would replace the whole device every six to eight months.

Keeping working air purifiers is important in our family. We have dogs, cats, foster kittens and the dreaded dust bunnies. I keep small GermGuadian air purifiers in my bathrooms currently. I will be getting two more to place in the foster kitten room and my guest room. I keep bigger GermGuadian air purifiers in other parts of our home.
