Germ Guardian 4825

At 22 inches tall, the Germ Guardian isn’t the most compact unit we’ve seen. However, it is more than capable when it comes to combating mold and other airborne particles.

The Germ Guardian has three fan speeds and can comfortably cover an area of over 160 square feet.

The two-level filtration system, combined with UV-C light technology, ensures the air in your home is clean and free from bacteria that can cause mold.

The final part of the PureZones three-stage filtration system is a UV-C photocatalyst filter that kills germs, bacteria, and airborne viruses.

Our Top Choice for the Best Air Purifier for Mold Problems

Colzer Air Purifier

The COLZER Air Purifier

Just sneaking ahead of the Levoit Core 300, the COLZER not only provides massive coverage in the home, making it particularly useful in basements and attics but it also has an incredibly level of filtration performance. It’s well designed, user friendly, and looks fantastic.

The amount of filtration provided is ahead of the other products reviewed, and while the unit is bigger than the others, it is exceptionally quiet in operation. This machine really can be used anywhere around the home or office where mold is a problem.

Its automatic air sensor system is fantastic and that means that once the unit is plugged in and turned on, it can do its job without a massive amount of input from the user. The machine’s ability to sense when air quality is not at its best is surprisingly accurate.
