Other Features

As we already mentioned, the air purifier uses an advanced three-stage filtration system that is specifically designed to reduce allergens and odor inside your home. The pre-filter screen will filter the air that enters the device’s filtration system. This pre-filter will capture large airborne contamination, including dust, pollen and pet hair. The second stage is about the air passing through the True HEPA filter. This stage will help the machine capture 99.97% of airborne pollutants. The third and the latest stage is the filtration process which is the germicidal or UV-C light treatment. This will purify the air from bacteria and viruses present in the air. Furthermore, this light will also activate titanium dioxide that is very helpful in the decomposition of the remaining molecules in order to release purified air. Actually, this is one of the best features of the GermGuardian AC9200WCA air purifier. It is highly-regarded for its efficiency in eliminating viruses that tend to be the primary culprits of most diseases, including bronchitis, meningitis and pneumonia. In addition, this air purifier is accompanied by an ionizer that emits negative ions. This is an amazing feature that will help the machine attract multiple microscopic airborne allergens in order to form a larger particle so that the HEPA filter can trap it. Plus, the ionizer is helpful in boosting allergen control capabilities. The AC9200WCA also come with a filter change reminder that will announce you when the filter needs replacement.


If you are thinking about buying the GermGuardian AC9200WCA, you should also know that the manufacturer provides a limited 3-year warranty, so you will be able to enjoy the great performance of this device with peace of mind.
