GermGuardian Air Purifier UV-C Replacement Bulb, LB4000, for AC4300, AC4900 and AC4800, AC5300

I searched many places and could not find the correct replacement bulb for my air purifier. Not once did I think of going directly to GermGuardian website. Once I did and just like that I found exactly what I needed. I could not be happier because I know it's a GENUINE Replacement UV-C Bulb for Air Purifiers.

Very pleased with purchase. Delivery was fast. Had some difficulty replacing the bulb in the purifier. Tight fit. Over all great experience and pleased with purchase.

I'm so glad I was able to find the bulb. We really like the air conditioner. Will be purchasing another one in the future for our home in Ohio. I have allergies bad, and this has helped a lot with the pollens in Arizona.

The UV light is a great feature on your HEPA filter system! Keeps us healthy from flu and other viruses.

Installation is relatively easy. I've replaced the bulb multiple times before. It's that extra security helping to keep the area germ free.

Entirely satisfied with price, shipping time, having received the right bulb for my purifier. No idea whether the bulb really does what it says it does, but the warning light stopped blinking so mission accomplished. Would order from here again.

Have had mine since June 2020 Love it. Does a great job ! Have many pets in the house and this is used in my bedroom. ( no pets allowed in B.R. ). Would highly recommend this product.

The unit is serving my hair salon quite nicely by filtering the air with the chemicals I use and Pandemic diseases. Provides the fresh air we need with lots of dust and other pollen in the air here. Thanks from SF, NM

The units as purchased have worked well since we received them. The parts were merely to have in the event of a need to replace parts to keep them operating.

Gives us peace of mind that we are breathing clean air.
