I am really allergic to mold and this really helps. I leave it on all the time and already have replacements when I need to change. Well packed by Amazon too

Replacement UV-C Bulb for germguardian LB4000 AC4800 Series
The manufacturer wanted $34.99 for this replacement bulb. I could not find this replacement part at Target where I purchased the air purifier. But then Amazon came thru by not only having this part that needs replacing once a year or more, but they had it for $12.00 from LightShopDirect! I will shop Amazon all day long when they save me almost 66%. It arrived quickly and in a box that was in a padded envelope. Shipping cost was $4.99 but still worth it.
