It comes with a HEPA filter that captures 99.97 percent of airborne particles with a size greater than 3 microns, including dust mites, pet dander, pollen grains, and mold spores.

GermGuardian AC4200: Control panel

To improve air quality, simply press one of the two buttons on the simple control panel. This air purifier uses the latest technology to filter dust and chemicals. In addition, it utilizes a quiet three-speed design that provides whisper-quiet operation so you can enjoy better health in your home or business without disturbing others.

This control panel displays the air quality in your home or business on the LED screen, so you can see how well it’s working at a glance. 

In addition, the GermGuardian AC4200 includes an odor sensor that automatically detects odors and turns on the UV light to eliminate them. This feature is great for people who have recently had guests who might have smoked. In addition, using UV light will eliminate any residue left in the air.

The GermGuardian Air Purifier: Specifications

You can use GermGuardian Air Purifier in two methods. 

• The standard mode is to run the air purifier at its standard operation, which removes allergens and contaminants around you at their source. 
• The UV-C mode runs the UV-C light as it does in a common air purifier. However, this mode also activates the 3D Carbon Pre-Filter for effective trapping of larger particles to prevent them from entering your HEPA filter.

GermGuardian Air Purifier: HEPA Filter

The special HEPA filter uses a type of ceramic that traps airborne particles up to 0.3 microns in size while letting smaller particles pass through. The HEPA filter also has a patented design that can hold up to 300 times its weight of particles without losing its ability to work.

GermGuardian Air Purifier: 3D Carbon Pre-Filter

The 3D carbon pre-filter helps to remove large particles from the air before they ever make contact with the main HEPA filter. The 3D Carbon Pre-Filter can hold more than 30x its weight without losing effectiveness.

GermGuardian Air Purifier: UV-C Light 

The UV-C light (ultraviolet C) works by producing an ultraviolet ray that penetrates the HEPA filter and can kill airborne pathogens. To ensure that the UV-C light will work effectively, replace the UV-C bulb when it reaches its maximum time, or else it may have no effect on airborne pathogens.

GermGuardian Air Purifier: UV Indicator Light

The UV indicator light will determine if your air purifier is working and whether or not the UV-C bulb is still effective. If there is no light, you should change the bulb as soon as possible because it will likely stop working.

GermGuardian Air Purifier: Timer 

You can set the air purifier from GermGuardian to run for as little as an hour or as long as 12 hours. While the 6-hour timer is the recommended setting, it’s possible to customize your air purifier to your personal needs.

GermGuardian Air Purifier: Sleeping Mode 

You can activate the sleeping mode by flipping a switch on the top of your air purifier, and it will change the fan speed from medium to low so that you can use your air purifier in a bedroom overnight.

GermGuardian Air Purifier: 5 Fan Speeds

You can adjust the fan speed in your GermGuardian Air Purifier based on how much coverage you need. The lowest fan speed reduces germs and allergens as it circulates air through the room, while the highest setting works great in larger rooms or outside spaces where large amounts of contaminants are present.

GermGuardian Air Purifier guides

• Do not use a UV-C light bulb from another brand with your GermGuardian Air Purifier. This could disable the UV-C function and cause you to lose coverage.
• Remember to change your UV-C light bulb in time. Even if the UV indicator light does not turn on, this does not mean that it is still effective. If there is no indicator, you should replace the bulb immediately.
• The UV-C bulb in the GermGuardian Air Purifier can get extremely hot, so be careful not to touch it for extended periods.

GermGuardian Air Purifier: Power Saving Mode

Depending on how much dust and dirt is in the air, the GermGuardian Air Purifier can use up to 30% less power. Simply switching a switch on the air purifier’s side will allow you to reduce your electricity consumption and save money over time.
