Germ Guardian AC4300BPTCA Air Purifier

A good choice for those on a budget is Germ Guardian’s AC4300BPTCA Air Purifier. The HEPA filter removes 99.97 percent of airborne particles as small as 0.3 microns, including pet dander and dust mite debris.

AC4300BPTCA is also one of the few air purifiers with UV-C light. To eliminate volatile organic compounds from the air, UV-C lights are often used in conjunction with photocatalytic air purifiers. A UV-C light can add some of the benefits of these types of purifiers at an affordable price.

In addition to the on/off switch and three fan speed settings, the Germ Guardian’s digital display displays the time, room temperature, and relative humidity. A soft nightlight is included for a more restful sleep, but it is not very bright, so it won’t light up the room enough to guide you through the night.
