bacteria are human enemies that scientists have always come with ways to get rid of and this filter is one of these. This Charcoal filter is able to stop the growth of these bacteria which could trigger dangerous health conditions. The Activated carbon filter performs also the task of reducing common odors from pets, smoking and cooking. This is a very interesting feature because no one likes to see his guests waiting for the next opportunity to rush out of the house due to repulsive smoking or pet odors.

UV-C Technology

Another threat which is unseen to the eyes, and which you’re probably exposed to, are airborne germs. Germguardian’s Ultra Violet light works along with Titanium dioxide to exterminate these airborne germs. In other words, when the air is sucked in, the light hits it and kills the bad germs then blows the good air out. The UV-C can be turned ON or OFF via UV-C Mode button. To keep this process of killing airborne germs effective, the light bulb inside this unit should be changed at least take six-eight months depending on the frequency of use.

This air purifier a digital display panel to enable you to control the functioning of the unit in a way that matches your needs. The digital panel is easy to use and includes UV-C control, a filter change indicator and a timer. The fan speed has 5 levels to raise or lower the speed by which the air is cleaned. It was reported that only the first three levels are quiet, especially the first one which is ultra-quiet, ideal for sleeping. This wide range of speeds is very useful because when it’s daytime, the need for cleaning indoor air is generally more urgent (high fan speed), while at night, and to have a good sleep away from the buzzing sound of the fan, the lowest level is the adequate one.
