How It Works

The multiple levels of cleaning of the GermGuardian Elite 28” 4-in-1 Digital HEPA Tower with UV-C Air Purifier with Digital Display include a combination of True HEPA filter that captures allergens and a charcoal filter to remove odors. The Charcoal (a.k.a. Activated Carbon) pre-filter captures initial dust and allergen particles while contributing to the control and prevention of the growth of bacteria, germs, and mold. True HEPA Filter captures 99.97% of dust and allergens as small as .3 microns such as household dust, pet dander, and plant pollens. The UV-C light technology works with Titanium Dioxide (TiO2) to enhance the elimination of airborne germs. TiO2 is activated by the UV-C light to decompose remaining odor molecules caused by smoking, cooking, and pets.

Additional Features

This Energy Star Certified air purifier features a built-in timer and handle for easy portability. It also has two different reminder lights; one alerting you when to change the HEPA filter and one showing when to replace the UV bulb. Both are easily reset with the touch of a button.

Filter Changes

Changing the filter for the GermGuardian AC5350 Air Purifier is a breeze! Simply press the Lock & Release Button, remove the cover and filter, pop in the new filter, and snap the cover back on. Replacing the filter doesn’t require any tools or mechanical know-how. Unlike many other air purifiers with filter indicator lights, you can reset the indicator with the touch of a button without any tools!

Replacing the UV-C Bulb requires removing two screws using a Philips head screwdriver. To get to the bulb you must removed the back panel and filter, then remove the UV-C Metal Shield by unscrewing the two screws. Then pull the bulb straight out. Slide a new bulb into the slots and replace the Metal Shield, filter, and back panel.

Air Flow and Positioning

The GermGuardian AC5350B Air Purifier pulls air in from the back of the purifier and blows clean air out the front. Place your air purifier so that the air intake and outflow are not impeded.
