Common Sense is needed.

I just got a few of these. Yes, it makes a some noise, yes it's cool looking but I think most people are missing the point. It's obvious that many people don't truly understand the nature of this product.
I think expectations have to be better managed. I agree the claims and marketing are a bit misleading. The marketing materials seem to be very dumbed down. That said, if you're looking to buy one, you need to understand what it is and what it ISN'T. Firstly, it's NOT A FILTER. It says so right on the website. Filters are basically dust catchers. So you can't fairly compare it to a HEPA filter. For lack of a better term, this thing is an air sanitizer. Just like using bleach to kill germs in your bathroom or using Purell hand sanitizer on your skin. It kills airborne germs and pathogens. Things in the air that can make you sick.
This company makes the industrial version of this for food processing plants and hospitals where sanitary air is important.
From their industrial products website:
Photocatalytic Oxidation (PCO)
The technology used in AiroCide Air Purifiers combines two known pathogen-killing techniques, Photacatalytic oxidation (PCO) and ultraviolet light to destroy harmful airborne microbes. The oxidant used in PCO is the oxygen that makes up 20% of our air. Because the concentration of oxygen in air is so much larger than the (total) concentration of gaseous indoor air pollutants, it is not necessary to employ additional oxidants such as ozone (O3) or hydrogen peroxide (H202). The system produce no oxone and are not filtering systems.
Titanium dioxide (TiO2) is the photocatalyst used. A unique process is used to create the patented TiO2 formula that coats the catalyst material. When this material is irradiated with the ultraviolet photons from the lamps inside, hydroxyl radicals and super-oxide ions are formed. These elements will oxidize (reduce to trace elements of carbon dioxide and water) volatile organic compounds (VOC's) absorbed on the catalyst surface. They will also kill and decompose airborne pathogens. Because the organic material is completely oxidized by this process, the photocatalytic reactor is self-cleaning relative to organic material on the catalyst surface.
They have essentially created a home version of an industrial air sanitizer that has proven it's worth in commercial settings. But I can see how it's difficult to connect this idea to consumers. I think that's why the marketing is vague and this product is misunderstood. It's difficult to briefly describe what this product does.
So in a nutshell, it's not an air cleaner. It doesn't filter or catch anything. It's a sanitizer. If you want a reduction in dust and airborne particles, get a filter. If you want to sanitize the air, get this. If you're a clean freak, get both.
