Key Features of the GermGuardian AC4825

1.  Filtration System

The GermGuardian air purifier has a 3 step process for cleaning your air and getting rid of the pollutants. The first step is the filtration of the air via the prefilter and the carbon filter. Then, the prefilter removes the dust, hair, fur, etc. present in the air. Finally,  the carbon filter gets rid of any unpleasant odors and smells present in the air.

This filtered air then passes through the HEPA filter that captures very fine particles like pollen, dust mites, allergens, etc.

After the HEPA filter, the air then passes under a UV light that kills any bacteria or viruses in the air.

2.  Germ Fighting Ability

The optional UV-C light technology works with Titanium Dioxide. This means that this air purifier can reduce airborne bacteria, viruses, germs and mold spores.

3.  Air Circulation

Designed for rooms up to 167 sq. feet, the GermGuardian can filter and circulate air over four times very hour.  Additionally, the unit is AHAM Verified which means that its ability to clean air has been verified by the American Home Appliance Manufactures Organization.  This means that you can trust the verified Clean Air Delivery Rate (CADR) for Dust (118), Pollen (125) and Smoke (108).

4.  Filter Change Warning Light

We’re all crazily busy and so remembering when the air purifier needs to have its filter changed is probably pretty low on our priority list. However, the GermGuardian AC4825 solves that problem for us. This air purifier comes equipped with indicator lights that start to blink when it’s time to replace the Filter or the UV-C bulb.

There’s only one filter which needs to be changed and depending on the use that’s going to need doing every 6-8 months. 

5. Ready to go Out of the Box

The product is very easy to use. It comes completely assembled. So, all you have to do is to plug in the air purifier, turn on the switch, and you will be good to go!
