Average Reviews:
(More customer reviews)I purchased two of these based on all the positive reviews and when they arrived I was initially thrilled. Until I opened the device and realized that its basically a fan with 2 small furnace-style filters. That's it. There is no real "sealing" of the air path so lots of leakage around the filters is guaranteed. Next, the filters themselves are simple furnace-style filters and not true HEPA filters like what was implied in the advertising.
If you look at the CADR ratings, the dramatically lower score for smoke vs. pollen or dust tells you that the filter really designed for larger particles above 1.0 micron. This is ok for dust and pollen but won't help for anything smaller like bacteria, viruses, and sub-micron contaminants. So if all you want cleaned out of the air large dust particles and bigger pollen, you might be happy with this filter.
This is a very inexpensive (read: cheap) design. Don't let the name and the good looks fool you...this is basically a plastic container with a fan on top and two cheap paper filters on the bottom. If you want something that is more than just a dust and pollen filter (like what you find on your furnace or in your car), then you should look elsewhere for a true HEPA filter with good air sealing.
As an aside, they list CADR certification when in fact not a single Vornado product is listed on the CADR site.

Purify the air in your home with the Vornado AQS500, which circulates and filters clean air throughout the entire room (up to 324 square feet) thanks to Vornado's exclusive Vortex Action Technology. It draws air through two high allergen/maximum dust air filters to trap pollen, pet dander, bacteria, mold spores, dust mite debris and smoke particles. The Vortex Action Technology circulates the air in the room, which maximizes its cleaning capability instead of just focusing on the immediate area around the unit. Equipped with LED indicators that display personal settings, the AQS500 features 3 speeds, a timer, and a change filter indicator to aid in the timely replacement of filters (2 filters included). The unit provides 4 air changes in rooms up to 324 square feet; it measures 13-4/5 by 10-2/5 by 24-1/5 inches (WxDxH) and weighs 12 pounds. It's backed by a 5-year limited warranty.
Clean air delivery rate (CADR):
185 Pollen
149 Dust
102 Smoke
Clean Air Delivery Rate (CADR) indicates the volume of filtered air delivered by an air cleaner. Created as a standard to compare the effectiveness of air purifiers. The number rates the volume of air that is filtered by the unit when it is cleaning each of the contaminants from the indoor air.
