The UV-C light is built into the filter chamber and shines on the air as it passes through the HEPA filter. It helps inactivate bacteria, viruses, and mold spores that may be caught in the filter. The UV-C light is contained within the unit and doesn't shine into the room, so it's safe to use around people and pets.
The HEPA filter should be replaced every 6-8 months under normal use. If you have pets, smoke, or have especially dusty conditions, you may need to replace it more frequently. The UV-C bulb typically lasts about 10,000 hours of use, which is roughly 12-18 months with daily use.
It's reasonably effective at reducing pet odors thanks to the activated charcoal filter, but it won't eliminate strong odors completely. For severe pet odor issues, you'd want a unit with more activated carbon. It does a great job with pet dander and hair through the HEPA filtration, which is the main concern for most pet owners with allergies.
The GermGuardian AC4825 is a solid budget air purifier that offers good value with its 4-in-1 filtration system. The UV-C light adds a layer of germ protection that most budget purifiers lack, and the slim tower design fits well in small spaces. While it's not the quietest or most durable option, it delivers reliable HEPA filtration at an affordable price. For pet owners and anyone looking for basic air purification on a budget, it's a strong contender.
