Yes I would this product again

Easy to install, came exactly as advertised

By: Tom

A great product for confined places

I bought the LB1000 UV Air Sanitizer for my bathroom. I had another product that was good, but not great. The first time I used it I noticed that my bathroom smelled fresher. Sadly, my original bulb went red, meaning I needed to replace it. I bought two and plan on buying another LB1000 UV Air Sanitizer for my bedroom.

Works from what I can tell

My daughter is able to sleep through the night without any congestion. Do I really need to add more words?

It cleans the air

Have been using this product and think the air is cleaner. Use it in the kitchen family room area plus the bedrooms.

By: Charles Ramos

Works great.

This item is exactly what I was looking for. Original packaging, bubble wrapped and it got to me quickly. I do wish it was available as a single item and not only as an add-on though.

Replacement Bulb Works Fine

The bulb was easy to replace, and has been working very well. This was kind of a relief considering some people have had problems with these bulbs. The original bulb lasted for over a year, hoping this one will also have a long life. The only down side is that these bulbs are very expensive.

does the trick

It works well in my toothbrush sanitizer. We have been using it now for several months and it functions as needed to.

The bulb works

The Germ Guardian started up right after I plugged it in. I can see the bulb is working fine. Only challenge is taking apart the Germ Guardian apart to get the bulb in.

I have used the germguardian for several years and highly recommend it - it is especially good at "dust" reduction! Our cleaning people asked for info so they could "share" the product with other clients! Miss being able to buy replacement bulbs from our local Home Depot and Lowes stores. However, buying "online" worked well for me.

UV Bulb works long and well

It was time to replace the spent UV bulbs in my 2 germguardian air cleaners. The bulb is obscure enough to find, but I found a great deal, here. Thank to this UV bulb, nobody can tell that I have 3 indoor cats, until they sit on one. I have used the air cleaners for health reasons, but am always surprised that such a small machine with such a small bulb can conquer that monster stench, for up to a year, per bulb...non-stop. When the bulb stops, my nose knows and It is replaced with ease. I highly recommend it.

So wonderful to repair something instead of having to replace the whole product when most things today are built in with obsolescence in mind.

By: L. Totten


I thought this would be hard to find and it wasn't. I was so annoyed about looking for this lightbulb and look how easy it was to find! Cheaper than replacing the guardian!


germguardian LB1000 Replacement Bulb

This bulb has been stable in its function and lasts approximately 1 year with continues use. I have two products that utilize this bulb and I have had to replace the bulb only once a year. That is acceptable for its intended use. Cost is acceptable considering what the intended use is for and the construction of the bulb. It is not light in construction. I own two of the Germguardians and first noticed them in clinics where small spaces for patient visits were performed. 5 Stars for product function and cost. Highly recommended.

Works Great

Replacement for the original bulb. Price was fair and bulb was easy to replace. The Original lasted about 8 months. I don't know if this product really prevents airborne diseases but doesn't hurt to have it.

Buy when your current bulb turns orange

It is pretty straightforward - when the existing bulb in your GermGuardian unit starts taking on a purple/orange-ish tint, it is time to buy one of these. Ours lasted a little over a year of continuous use before giving up the ghost.

I have been using this product for 7 years now and I have been nothing but pleased with it. I live in an Independent Living apartment, I have 2 CATS and there is a distinct possibility of litter box odor, but with Germguardian in each room, there is never an odor. When it stops, I just order a new replacement bulb and continue enjoying the fresh air.

By: Holly Luedke

Works wonders, lasts over a year

I love this product! A non-toxic way to clean the air. Made well, and bulb lasted over a year with it being almost continually plugged in. Whisper quite... sounds like white noise.

By: mariakam

It works great!

We have no problem with this bulb. It reached us in excellent condition and it works great.

Gets rid of stink

This was a replacement bulb to go in our germ guardian GG1000. The item is well worth the hefty price tag. It sits above cat litter box around our kitchen and because of the effectiveness of the germ guardian we would forget to change the litter box till the cats reminds us to. Before the germ guardian we couldn't stand the smell in 3-4 days after cat litter change.
