About GermGuardian AC4825

The GermGuardian purifier is a three-in-one system that incorporates the HEPA filter recommended by the Environmental Protection Agency (EPA) and the American Lung Association to capture and eliminate dust, particles, pollen, and odors from the atmosphere. One of the interesting features which really makes it so efficient is the UV-C light sanitizer that kills airborne bacteria trapped inside its filters.

The system cleans the air in your house and all indoor air pollutants, leaving it allergen free while improving its quality. This should be of particular interest to individuals suffering from asthma and allergy.

The purifier is a three-step system that employs three methods to clean air – now you know why I’ve been mentioning ‘3-step system’.

In a nutshell, the first step involves the vent forcing air through the pre-filter and running them through the activated carbon while preventing large particles like hair, dust particles, pollen and lint from passing through.

At the second stage, HEPA (High-Efficiency Particulate Arresting) traps smaller particles like tobacco smoke, and at the final stage, the UV-C kills off any airborne bacteria floating around.

Stage 1: The Filter and Activated Charcoal

The pre-filter vent is a fine mesh material with activated carbon – now activated carbon is a type of processed charcoal with an increased porosity – that traps large particles from entering and clogging the filter. Think of the pre-filter screen as would about your window screen.

After, this stage, the air is forced through the HEPA filter for the next step.

Stage 2: The HEPA Filter

For a filter to be called a HEPA filter, it must have fulfilled the minimum environmental standard of eliminating 99% of all particles that are 0.3 microns in size.

To gain perspective on this, let us assume that the air passing through the system has about one thousand particles. To be called a HEPA filter: only three out of the one thousand particles is expected to make it past the screen.

You see, purchasing a non-HEPA filter is just like throwing money away.

Stage 3: The UV-C Sanitizer

At this stage, the atmosphere is basically clean, however, the odds of bacteria pass through the filter system in the living room is high. This is where the UV-C and Titanium Dioxide filtering comes in. The Ultraviolet light sterilizes the air by killing off germs while the Titanium Dioxide breaks down any odor not captured during the earlier filtering process.
