Germ Guardian 3 in 1 Air Cleaning System
The GermGuardian AC5000E offers outstanding performance for the price, with true HEPA filtration that is capable of reducing up to 99.97 percent of allergens such as dust, pollen, and pet dander. This air purifier also uses an activated carbon filter to reduce odors commonly cause by sources such as pets, cooking, or smoking. A built-in UV light is used to kill airborne bacteria, mold, and viruses that can cause illness.
The AC5000E is a tower model and is able to effectively purify the air in medium-to-large sized rooms. Although it uses multiple filters, only the HEPA filter needs to be replaced; they can be rather pricey but this is only required every six-to-eight months depending on your individual usage. This air purifier is an excellent overall choice, while being quiet enough to be left on while sleeping.
