The GermGuardian AC4825 is an excellent air purifier that’s got a UV-C filter, three-stage filtration, and an energy-star certification. However, be aware of its lack of a washable pre-filter and low CADR rating & room coverage.

Overview

The GermGuardian AC4825 is a mid-range air purifier released in May 2011. It boasts deep air cleaning and complete sterilization thanks to its true HEPA filter and the UV-C filter, respectively. In addition, its pre-filter includes a layer of activated carbon (charcoal) that helps absorb smoke and bad smells from its designated area. It is also very easy to maintain and claims to come with a low long-term cost.

Thus, it is a superb option for buyers looking for a good air purifier in its range that sterilizes the air. To learn more about what experts think about it, continue reading our GermGuardian AC4825 review down below.

What the brand doesn’t always tell you…

our Verdict

The GermGuardian AC4825 is a great air purifier for small spaces. It has three fan speeds, a UV-C filter, three-stage filtration, and an energy-star certification. Just be aware that it doesn’t have a washable pre-filter, has a low CADR rating, and doesn’t cover large rooms.
