One of the biggest advantages of this air purifier is the fact that it has respectable CADR ratings of 265 (pollen), 216 (dust), and 216 (smoke), which should work great for medium-sized rooms up to 335 sq. ft. The GermGuardian AC9200WCA uses a multi-stage filtration system that is specifically designed to reduce allergens and odor inside your home. The pre-filter screen will capture large airborne particles including dust, pollen, and pet hair even before they can enter the machine. The second stage involves air passing through the HEPA filter, which captures 99.97% of smaller particle pollutants. The third filter is carbon-infused, which means odor and smoke molecules from the air will be removed.

The filtration process also involves an optional UV-C light treatment. This will remove bacteria and viruses present in the air. Lastly, this air purifier is accompanied by an ionizer that emits negative ions, which can boost allergen control capabilities. With that said, know that this model is certified by the California Air Resources Board (CARB) for its compliance with the federal ozone emission limit, which means that you shouldn’t worry about ozone in spite of its ionizing function.

As a final note, its HEPA filter appears to work great against common particle pollutants. It’s not a True HEPA filter, however, which is something we expect from a purifier at the AC9200WCA’s price point.

Other Features

The AC9200WCA comes with a filter change reminder that notifies you when the filter needs replacement. It also features three speed options, which enables you to adjust the purifier’s cleaning power as you see fit. The last notable convenience brought by this model is its timer, which can be set to up to six hours.


This GermGuardian device is a sleek and attractive air purifier that measures 17 inches in width, 9.75 inches in depth, and 27 inches in height. The AC9200WCA also features a UV-C on/off switch that enables you to switch on the UV-C light treatment function. Aside from being a stylish and compact device, this air purifier is also pretty easy to operate. It comes with dedicated controls for adjusting fan speed, turning on the ionizer, and setting the timer. It also has a dedicated filter replacement indicator on the control panel.

Warranty and Support

If you are thinking about buying the GermGuardian AC9200WCA, you should know that the manufacturer couples it with a limited 3-year warranty, which is a respectable length for a standard air purifier.

Final Thoughts

The AC9200WCA is certainly one of the most promising air purifiers on the market. What we like most about this product is the fact that it features an additional ionizing and UV-C light functionality that helps combat viruses and bacteria, thus creating a safer living environment. Those who have small children will especially appreciate this feature as it greatly reduces the risk of infections and illnesses. Overall, we consider it to be a great option if you’re looking for a mid-level to premium air purifier.
