The GermGuardian AC3200 AirSafe+ is a 20-inch tower air purifier with a four-stage filtration stack: a fabric pre-filter, an activated carbon filter, a True HEPA filter rated to capture 99.97% of particles down to 0.1 microns, and an optional UV-C bulb. IntelliSense monitors the air 60 times a minute and sets fan speed automatically across 10 settings, and the unit is rated to clean a 348 sq ft room in about 12.5 minutes. It suits bedrooms, living rooms and offices where odors and pet dander are the main concern. Against rivals like the Coway AP-1512HH and Levoit Core 300, it adds UV-C and a washable fabric pre-filter but uses more energy and needs three separate replacement parts.

Owners generally rate the AC3200 well for odor removal and auto mode, and many like the adjustable fan noise for sleep. Complaints center on filter and bulb replacement costs and on the unit's size.
The GermGuardian AirSafe+ XL is a 20-inch tower air purifier for bedrooms, living rooms, offices and basements. It uses a 4-layer True HEPA filtration system that captures up to 99.97% of dust, pollen, pet dander and smoke as small as 0.1 microns (initial efficiency value).
A fabric pre-filter catches larger particles. An activated carbon filter reduces odors from pets, cooking, smoking and wildfires. An optional UV-C light helps reduce airborne allergens, germs, bacteria and mold spores. The UV-C claim was tested with Staphylococcus Albus, Escherichia Coli, Aspergillus Niger and Phi-X174.
IntelliSense technology checks the air 60 times per minute and adjusts the fan speed automatically. The unit has 10 speed settings, from quiet white noise for sleep to strong airflow for fast cleaning. It cleans a 348 sq. ft. room in 12.5 minutes, or up to 1,680+ sq. ft. every hour.
